How to Deal with Engine Difficulties

Keep your car running smoothly with by following these car engine maintenance tips.

There isn’t anything worse for a car owner to hear than the news that their car needs a new engine. But the truth is sometimes the engine in your car simply dies. While there are things you can do to help keep your engine healthy and your car on the road, it is also important to know what signs might signal trouble ahead. According to the Car Care Council’s website the following are all signs that there may be a problem brewing in the engine.

Excessive smoke pouring out of the tailpipe
Using excessive amounts of oil
Strange sounds like knocking or tapping
Low oil pressure
Oil getting into places it shouldn’t be like the air cleaner or radiator
Low engine compression
Water in the oil

If any of these problems happen, you need to take the care to your local repair shop immediately to have the engine looked at and any problems addressed. This can make it possible for you to catch a problem early enough that it doesn’t result in having to completely replace the engine.

There are several things that can cause engine problems.

Normal wear and tear
Not performing regular maintenance like oil changes
Lubrication issues
Constant overheating

It is important to remember that ignoring engine problems is never going to make them go away or get any better. In fact, most of the time, ignoring it will only make it worse. And you may end up with an engine that simply dies. If this happens to you, you will need to decide if it is worth replacing the engine. For some cars, the high costs associated with engine replacement paired with the value of the car make engine replacement a bad investment.

But before you consign your car to the scrap heap, make sure you know all the information. First, you need to know how much your car would be worth with a replacement engine. Then, you need to know what the engine replacement will cost. Factor in what you owe on it and if replacing the engine leaves you with a good car that is worth more than what you owe plus the cost of the engine replacement, getting it fixed is the wiser choice.

If you choose engine replacement, you need to understand the different terms you are likely to encounter in order to make the best possible decision. If you have to replace the engine in your car, you may want to consider using a rebuilt or remanufactured engine rather than buying something brand new. These engines are rebuilt to specific standards and specifications by highly skilled technicians. In some cases, a rebuilt engine may actually be better than the original engine installed when the car was built. So don’t overlook this kind of engine replacement options as being less than something new. The key is to find a repair shop you can trust who will recommend the best possible parts to get you back on the road.

How Can Carbon Build Up Impact My Engine? (virginiaautoservice.com)

Ask the Car Guy: How Can Carbon Build-up Impact My Engine?

Matt Allen, Owner of Virginia Auto Service, cohost of Bumper to Bumper Radio

Dear Car Guy,

I keep hearing about carbon build-up and that it can hurt my car. Can you please explain what carbon build-up is and how it can impact my engine?

Thank you,

Bill Q., Phoenix, AZ

Hi, Bill,

Many car manufacturers are now using direct-injection (DI) technology in their new designs because it increases fuel efficiency (meaning MPG).

This technology, which was initially created to make diesel engines quieter and more fuel efficient, changes the way fuel enters the engine. This change allows carbon, a black sooty dust, to build-up on the engine’s intake valve and other surfaces inside the engine.

In port-injection engines, the fuel enters the engine before the intake valve. This means that the fuel is flowing over the valve as part of the engine’s normal operation. Most gasoline sold today contains additives whose sole job is to help remove carbon from the intake valve and other parts of the engine and these additives do their work as the fuel flows into the intake valve. But DI bypasses that process, injecting the fuel directly into the cylinder. This means the additives in the fuel never come in contact with the surfaces most likely to experience carbon build-up.

When carbon builds-up in the car’s engine it can cause a couple different problems. First, the engine will lose power. One of the main problems carbon build-up does is to change the ratio of fuel to air in the engine. This can happen if sensors stop functioning properly because of carbon build-up or if build-up keeps the intake valve from closing properly. This can make the engine sluggish and cause it to stall. Carbon build-up can also significantly degrade fuel efficiency, causing the car to get fewer miles to the gallon than it should be getting.

There are some things that will cause carbon to build-up faster that those with cars that are prone to carbon build-up problems should avoid. Filling the tank with low grade gasoline which is less purified and usually has a higher concentration of contaminants can increase carbon build-up in the engine. If the ratio of fuel to air is off, as mentioned above, carbon will accumulate more quickly. Using the car primarily for short trips can also increase problems with carbon build-up as the engine doesn’t run long enough or hard enough to get hot enough to burn any of the carbon off.

The cars that are at the highest risk for carbon build-up problems are those that use DI, although not all cars that these types of fuel injection system have experienced this issue. Audis, Mini Coopers, and some VW and BMW models are the cars that seem most prone to carbon build-up. For owners of these cars, the carbon build-up problem means they must invest in additional maintenance on a regular basis to have the carbon cleaned from their engine.

When cars experience issues with carbon build-up, the build-up must be cleaned out of the engine. Most auto repair shops can perform this kind of service but it can be costly, depending on the type of car and the work required to remove the build-up. If your car is having any of these problems, have your repair shop check it over and recommend what can be done to solve the immediate issue and over the long term to protect your engine and keep your car on the road.

Why does my car sputter on acceleration?

Does your car sputter when you step on the accelerator? If yes, it could be because you are low on gas.

However, if your tanks are full, then it could indicate a different kind of car trouble starting from either the fuel system in your car or a faulty exhaust or even worn out parts.

It is important to note that the problem will not self-correct over a period. If left unaddressed, it can lead to expensive repair costs which are not appealing even in the age of lower taxes.

Why does my car sputter on acceleration?

Here are five of the most common reasons why your car sputters when you accelerate.

1. Failing Catalytic Converter

If your car has a faulty or a failing catalytic converter, the engine will sputter or run rough.

When the catalytic converter is faulty, its ability to burn hydrocarbons within the exhaust get hampered which means the breakdown of sulfur produced by the engine will no longer happen.
For this reason, you may get a smell akin to rotten eggs if the catalytic converter is failing.
Another symptom that your catalytic converter is failing is when your dashboard lights up with the “check engine light.”
If the catalytic converter gets completely blocked, the car will not start.

2. Dirty Fuel Injectors

The job of the fuel injectors is to supply the cylinders with required fuel which mixes with the air and ignites. This ignition is necessary to power up the engine.
However, over a period, the fuel injector nozzle can get blocked leading to the engine sputtering when you accelerate.
Timely cleaning of the fuel injectors can prevent any kind of clogging. If, however, the fuel injectors are not routinely cleaned, they can get damaged and will need to be replaced.

3. Dirty Spark Plugs

If the spark plugs which help the fuel ignite within the combustion chamber are damaged or dirty, they will not be able to ignite the fuel.

When this happens, the engine will sputter, or you may experience a misfire. At this point, the spark plugs will have to be cleaned or replaced based on the level of damage and you don’t want to be doing this on the side of the road in a Phoenix summer.

4. Faulty Oxygen Sensors

The job of oxygen sensors is to keep a track of exhaust gases for how rich or lean they are at the point of leaving the combustion chamber.
This information is then passed on to the computer which then makes the necessary adjustments to the quantity of fuel inside the engine.
If your oxygen sensors are damaged or dirty, they will not be able to pass on this critical information to the car’s computer which means the computer will not be able to adjust the fuel entering the engine leading to the engine sputtering.
If you take your car for routine maintenance, your car technician will ensure they are replaced as and when required.

5. Leakage in the Exhaust Manifold

If your exhaust manifold which is responsible for collecting the exhaust gases springs a leak, you may experience your car engine sputtering upon acceleration.
Your engine will also become very noisy and its overall performance will drop.
The danger of a leak in the exhaust manifold is that the hot gases can damage the surrounding car parts, or the exhaust fumes could also enter the cabin of the car.
One of the first signs to watch out for is the “check engine light” flashing on your dashboard.

Notify a Professional

If you notice any of the above-mentioned symptoms, it is best to have your car checked up by a professional car technician at the earliest.

Keep in mind that the sputtering will not go away; in most cases, if the engine sputters on acceleration, it could be symptomatic of a wide variety of serious car troubles.

If you ignore the problem, over a period, your car will suffer from dropping engine performance and eventually not start at all.

Routine maintenance can help address most of the car troubles that you face. During a service visit, your car technician will carry out a complete checkup of all car parts and make necessary repairs or replace the parts as and when needed.

Why Does My Car Engine Die Immediately After Starting?

A common complaint we hear at Virginia Auto Service is that a customer’s car starts fine but then the engine dies immediately.

Of course, most people will simply restart the engine in the hopes that the car will start. However, this may not happen in most cases. If the problem lies with either the electrical system or the fuel injector system, the engine may start but it will stop immediately.

We don’t advise continuing to restart your car since this will only worsen the situation. The best option is to have your car checked out by a professional car technician. The earlier you can identify the cause of the problem, the better.

Why Does My Car Engine Die Immediately After Starting?

5 reasons why your car can start and die immediately:

If your car starts but dies immediately, it could be due to these five issues.

1. Problems with the Fuel Injection System

One of the most common reasons for a car dying immediately after starting is when the fuel injection system is damaged, the internal combustion process will not run its course. Here’s what you need to know:

The air and fuel mix or ratio need to be in a specific proportion for the engine to start. So, if there is a leak in the fuel injection system, it will impact the air-fuel ratio thus creating a disruption in the internal combustion chamber.
Now, the engine might start even if the supply of fuel is not adequate – however, even if the engine does start it won’t be able to continue running since the fuel supply is disrupted.

2. Faulty Injector Control Pressure Sensor

The fuel injector can continue supplying the required amount of fuel to the internal combustion chamber only if the necessary pressure is maintained – a job that is carried out by the car’s engine control unit.

However, in order to maintain the pressure, the engine control unit depends on information from the fuel injection sensor.

The fuel injection sensor keeps track of the pressure in the fuel injector and this information is relayed to the car’s engine control unit which then ensures that the necessary pressure adjustments are made to the system.
Obviously, if fuel injection sensor is damaged and is unable to pass on critical information about the required pressure in the fuel injector, the engine control unit won’t be able to make the necessary pressure adjustments to the system.

3. Damaged or Faulty Carburetor

The carburetor helps in ensuring that the air-fuel ratio is maintained for successful combustion. So, if your car’s carburetor develops a fault or it is damaged, then it impacts the air-fuel balance.

The result is again the same – your car will start, however, without the correct air-fuel ratio needed to ignite the fuel, the engines dies immediately which is not something you want to happen in a Phoenix summer. That will be a terrible day for sure.

4. A Problem with the Ignition System

If there is a problem with the ignition system the engine will start, but it will die down just as quickly.

The fault could be anywhere in the ignition system – a problem with the spark plugs or the battery could be the cause. Either way, have it checked out immediately.

5. Engine Control Unit Issues

If there is a fault with the fuel injection sensor, it affects the performance of the engine control unit.

However, if there is a problem with the engine control unit itself, again the necessary pressure adjustments to the fuel injection system will not be maintained since the control unit is unable to read or process the information from the fuel injector sensors. When this happens, the car dies as soon as you start it.

Wrapping this Up

If your car starts and dies down immediately, then the best thing is to have it checked by a professional car technician.

As a professional car service with years of experience, our best advice to all our customers is this – if you notice a fault or a problem with your car’s engine, have it checked up as soon as possible.

It could be a small fault or a major fault. The main thing is to limit damage to the car and carry out the needed repairs or replacements to prevent further damage.

Why Maintaining the Right Mix of Fuel and Air is Crucial to Your Car Engine

The right air-to-fuel ratio is an important aspect of good engine maintenance. When this ratio is maintained, the circumstances inside the internal combustion chamber of the engine are ideal for ignition and general functioning of the car engine.

It is the job of the control unit of the engine to control the various components, including the air flow sensors, oxygen intake and fuel injectors, as well as emission sensors.

In case there is an issue with any of these components, it could impact the amount of fuel injected into the combustion chamber.

If too much fuel is injected, and the ratio of the oxygen is poor or less than the ideal amount, the fuel mix inside the combustion chamber is said to be a “rich fuel mix.”

Signs Your Car Engine Has Rich Fuel Mix

The car engine is designed to run on a set air-fuel mixture. Any time this ratio shifts in proportion (too much fuel and less oxygen), it can be harmful to the running of the engine and impact the overall performance of your car. Here are a few important signs to watch out for which indicate “rich fuel mix.”

Check Engine Light

Any issues with the engine will light up the “check engine” signal on your car’s dashboard. Keep in mind:

There is no way of knowing what exactly is causing the “check engine” light to light up on your dashboard until you have your car checked by a professional mechanic.
In several instances, when car owners ignore the signal for too long, the engine damage can be significant.
Repairs or engine replacement costs are among the highest, which is why our advice is to seek professional help as soon as possible.

Poor Gas Mileage

Excess fuel in the combustion chamber will have a direct impact on the way your car consumes gas. You will notice the following if the air-fuel mix in your car is rich:

Mileage per gallon rate will drop substantially, and this is no good in a city like Phoenix where everything is rather spread out.
You will have to refuel far more often, even when running the same distance or for shorter distances.
Addressing the rich fuel mixture issue is the only way to reverse the poor mileage.

High Level of Carbon Emission

An excess of carbon emission levels from the engine is a pretty good indicator of rich fuel mixture. It is good practice to get your emissions tested as part of routine maintenance.

Faulty oxygen sensors could also be the reason for failing an emission test. Either way, it is best to test the carbon emissions and identify the root cause of the issue in case you fail the test.

Dip in Car Performance Levels

The presence of too much fuel and insufficient oxygen will impact the performance of the engine leading to an overall dip in the car’s performance.

The air-fuel mix might still be able to power the ignition and provide steady compression, however, the car’s performance will take a gradual hit.
Over a period, the condition will get worse and eventually start impacting the engine performance.
The engine’s running will not feel smooth.
You might also notice rough idling (the car feels bouncier while driving).
Remember, when the car engine performs undress stress, it has a cascading effect on other parts of the car, including the mechanical and electrical parts.
Keep an eye on the tachometer – the needle will go crazy (bouncing all over the place) if there is a rough idling issue.

Key Symptoms

Low fuel efficiency is a major irritant not only because of the cost factor, but also because a car guzzling fuel at a fast rate will eventually develop all kinds of engine problems.

A drop in the car’s overall performance, low fuel efficiency, and any of the above-mentioned symptoms should worry you if you want to avoid engine damage.

Addressing the rich fuel mixture issue early on will help you save hundreds or thousands of dollars in the long run.

What is Motor Oil Sludge – And How Can You Prevent It?

Motor oil is often considered the lifeblood of your vehicle. Having regular oil changes is probably one of the most important maintenance tasks performed on your vehicle.

Motor oil lubricates the moving parts of your engine, reducing friction and keeping the engine cool. When the oil is new and unused it is a transparent and easily flowing liquid that combines a base stock with various additives. The additives hold soot and other particles while maintaining the consistency of the oil. With use, the oil builds up contaminants such as fuel, dirt, water, coolant, etc. It also oxidizes due to the intense heat of the engine. The combination of contamination and oxidization turns the oil into “sludge,” a gel-like fluid that can seriously damage your engine.

A basic understanding of how motor oil works:

Motor oil is either synthetic or conventional and absorbs and protects the engine from contaminants. However, after a period of time, the oil will reach its absorption capacity. When this happens, instead of carrying contaminants away, it will deposit them on the engine surfaces and any other parts in which it circulates. It will stop lubricating the engine and reducing friction and, instead, cause heat to build up in the engine. Clean motor oil acts as a sort of coolant for the engine, however, when it becomes oxidized sludge, it acts as the opposite. When the oil becomes overly oxidized and contaminated, turning into this sludge, you will notice that the oil pressure falls and that you get lower gas mileage.

Motor oil sludge development:

Motor oil sludge first accumulates on the top of the engine, in the oil pan, and the valve cover section.
Then it blocks the oil screen siphon and prevents oil from circulating in the engine.

When motor oil sludge develops you risk serious engine damage as well as damaging the timing belt, gaskets, radiator, and cooling system. If not taken care of, motor oil sludge could cause the engine to stall completely.

How motor oil turns into motor oil sludge:

When it is exposed to oxygen under high-temperature conditions, the motor oil oxidizes. The oxidation occurs more quickly when the motor oil is heated for longer time periods.
When the oil oxidizes, the motor oil molecules break down and combine with the dirt, metallic particles, fuel, gases, and other contaminants forming the thick, sticky sludge.
Heavy stop-and-go traffic can contribute the buildup of motor oil sludge, as well as frequent short trips.

How to avoid motor oil sludge build up:

Have regular oil changes performed per the intervals laid out in your vehicle specific owner’s manual.
When you start your car, check the dashboard for the Check Engine light and/or the Oil Change notification light. Either light may indicate the need to replace your motor oil.
Avoid driving in stop-and-go driving as much as you can. Also, avoid taking too many short distance trips. Walk, bike, or consider public transportation when possible.
If the gauge on your dashboard shows that your vehicle is heating up, make sure your mechanic checks for motor oil sludge.
If you see the oil pressure is low, avoid adding engine oil and instead have your vehicle inspected for motor oil sludge. If the oil pressure light is on, you should have it inspected and/or replaced completely as soon as possible.

The most important thing you can do for your vehicle is to make sure that you are always following the maintenance guidelines laid out in your owner’s manual. This is especially important when it comes to the motor oil, or you risk serious and expensive engine damage.

If your Check Engine light or Oil Change notification is on, schedule an appointment with Virginia Auto Service. We will check the engine for signs of motor oil sludge build up and let you know if your motor oil needs replacing. We may also check for other reasons why the light has come on. We will relate any findings to you and thoroughly go over your repair options and costs.

Why Your Engine Overheats

We’re sure you’ve seen it, a car pulled off to the side of the road, steam pouring out from under the hood. Maybe it has even happened to you. This unpleasant phenomenon is caused by an overheating engine. It is a common occurrence in Phoenix, Arizona, especially in the summer months.

Heat is, by far, your engines worst enemy. Making yourself aware of the reasons for a vehicle overheating -and understanding the necessary preventive maintenance routines- can help you avoid major engine damage. There are some common problems that cause an engine to overheat, including a bad thermostat, blocked radiator, failed water pump, and a leaky cooling system. Some conditions are simple, straightforward repairs, and others require hours of work and expensive parts.

What is Overheating?

Your vehicle’s engine functions properly within a certain temperature range. Depending on your vehicle’s make and model, that range is usually between 195 to 220 degrees Fahrenheit. Overheating occurs when the temperature of the engine climbs to a point where mechanical damage can occur- usually a sustained temperature of over 240 degrees Fahrenheit.

An overheated engine can cause serious damage to pistons, cylinders, bearings and valves, as well as other vital engine components. For this reason, you should never ignore the warning signs of overheating. You should shut down your vehicle at the first indication that your engine is operating above the preferred temperatures.

Signs that your vehicle may be overheating include:

Steam coming from the engine area
Temperature gauge spiking to the red zone
Engine warning lights – often shaped like a thermometer – illuminated on the dashboard

4 Reasons Why the Engine Overheats

Most of the causes of overheating come from a lack of circulation- which can be caused in different ways.

A leak in the cooling system. The leak itself isn’t usually what causes the engine to overheat, it’s the air that enters the cooling system. When there’s a leak, the level of coolant drops below recommended levels and air is sucked into the system and circulated. Air is, of course, lighter than coolant, and rises to the top of the cooling system. When this happens, it is what we call an airlock. An airlock is a large air bubble that cannot be pushed through the cooling system. Because of this, the cooling system stops circulating effectively and the coolant that is left becomes overly hot.
Cooling system blockage. As overheating is due to the lack of coolant circulation in the engine, a blockage would technically be an indirect cause. If the cooling system is blocked, the coolant can’t circulate to disperse heat, and the engine gets too hot. Some common cooling system blockages include:

Mineral deposits blocking the radiator
Foreign object in the cooling system
Thermostat not opening when it should

Water pump failure. A failed water pump is probably one of the most regular causes of overheating. The water pump is responsible for maintaining coolant circulation and is the most active component of the cooling system. After a period of time, the impeller in the water pump can break or wear out and no longer turn. Shortly after this happens, the engine overheats.
Too little engine oil. It is not as widely known that the engine oil plays a large part in engine cooling. The oil lubricates the internal parts of the engine to prevent friction- a main cause of heat in the engine.

How to Prevent Overheating

To avoid overheating, watch your temperature gauge and coolant levels and regularly inspect your belts and hoses. Make sure the radiator cap is working properly and replace it if needed. Remember to never remove a radiator cap when it is hot. Other ways to prevent overheating include:

Flushing the cooling system as recommended in your vehicle owner’s manual, or sooner if needed
Have coolant leaks repaired as soon as you notice them
Change your engine oil and oil filter at the recommended intervals

Watch the temperature gauge on your dashboard, if it goes into the red, or the “hot engine” light comes on, pull over and shut off your vehicle to prevent damage. Remember that if your car overheats even one time something is wrong with your vehicle and it needs to be fixed.

What You Should Know About Engine Misfire

What is engine misfire? When your vehicle’s check engine light appears on your dashboard, your engine is misfiring.

CarMD states that a misfire is when one or more of your engine’s cylinders are not providing power to the vehicle, with raw fuel possibly running into the catalytic converter. To avoid expensive repairs or possibly even a car fire, you should treat engine misfire as a severe condition that requires immediate attention. The longer you leave the engine to misfire the more damage will occur.

According to CarMD, there are three common reasons why this could be happening, and they all vary in cost and severity.

Ignition System Defect. This is the most common and usually the least expensive. Examples of items that fail to cause this type of misfire are: spark plugs, distributor cap and rotor, ignition wires, and coil(s)
Fuel System Defect. This type of repair can be more expensive due to diagnostic and repair times, and parts tend to be more costly. Example: fuel Injectors.
Internal Engine Defect. This is the worst-case scenario. Internal engine components are expensive and tend to be labor intensive to change. Example: cylinder head, pistons and rings, and timing belt/chain.

The occasional misfire may go by unnoticed, but regular misfire is hard to miss. The engine will feel rough, lack power, and use more gas than usual. At times, a misfire may feel like a vibration. A misfire can also cause an increase in hydrocarbon (HC) emissions.

If it’s time for your vehicle to have its emissions tested, and you’re dreading the hassle of waiting in line at the inspection station, we can help with our “Emission Valet Service.” It’s easy, all you need to do is schedule an appointment and drop the car off. We’ll take you to work or home and pick you up later. We do a couple inspections to make sure the car will pass, then we take it for testing. After you pass all you need to do is go online and complete the registration. No waiting. No hassle. Easy as pie! The cost for the Emissions Valet Service is only $49.95, and that includes the state test fee!

Note: Your car will not pass emissions with the check engine light on. You need to bring it to the shop for a check engine light diagnostic and we can tell you what’s going on.

Ignoring an engine misfire because the vehicle appears to drive “just fine” could lead to more damage, and costly repairs- like catalytic converter or engine replacement. Also, misdiagnosing engine misfire yields pricy results. The parts that are required to repair engine misfire are expensive, if you replace the wrong parts, you have wasted some money and will end up spending more on the right ones. Also, you fail to address the actual cause of the misfire, which could lead to further damage of the vehicle. So visit a professional, in the long run, your car and wallet will thank you.

If you suspect that your engine is running rough due to the engine misfiring, please feel free to contact Virginia Auto Service with any questions, comments or concerns you may have. And remember, that by addressing issues like engine misfire quickly, and performing regular routine maintenance, you maintain your vehicles safety and longevity.

Top 10 Things That Are Bad for Your Engine

The engine is the heart of your vehicle. And, just like your own heart, if you aren’t taking proper care of it, things can go wrong.

Here are 10 things that are bad for your engine:

Not Enough Oil

Oil not only keeps your engine lubricated and running smoothly, but it also provides cooling, cleaning and other such jobs. When oil is low and whatever limited oil is in the engine is pushed around, it becomes hotter and hotter because the oil isn’t allowed enough time to cool down a little before it makes its way back into the engine. Because of this, the oil wears out even faster leading to more oxidation, thermal degradation, and compressive heating at a faster rate. This breakdown of the oil results in: tar, sludge, soot, etc. These start to coat parts of your engine like the bearings, cylinder walls, and rings. This coating is often referred to as carbon build up and causes a lot of friction on engine parts. If you allow this to continue, the parts will begin to wear and you could eventually find yourself needing a whole new engine rather than just a simple oil change.

When your vehicle is running on little to no oil the engine oil light should come on. If this is the case, you should not be driving your vehicle until you correct the problem to avoid costly damage or even complete engine failure. Keep your engine healthy by always completing oil changes on time according to your vehicles owner’s manual.

Too Much Oil

Engines are made to operate on a specific amount of oil. Your oil pan has baffles that are designed around the normal oil level. When you put too much oil in your engine, you run the risk of the oil “frothing” because of the connecting rods and crankshaft pushing air into it. The air bubbles that get into the oil interfere with the oil’s ability to keep metal parts from rubbing together- not good. Also, over filling can result in “splashing” causing parts of the engine to become coated in burnt oil and minimizing that parts effectiveness. Stick to your vehicles recommended amount of oil to avoid costly damage.

Using the Wrong Oil

When you use the wrong oil in your engine, it can lead to reduced lubrication and a shorter engine life. You should always use the oil specified in your vehicle’s owner’s manual. The brand itself doesn’t matter, but the viscosity grade (10W-30, for example) does. Also, if your owner’s manual says that you should be using synthetic oil, then you should do so.

Dirty Air Filter

The air filter is exactly what it sounds like. It filters the air of dirt and debris before it mixes with the fuel and burns in the engines cylinders. Dirty or worn air filters allow dirt and debris to enter your engine which can cause premature wear to things like the carburetor, cylinders, and pistons. Dirty air filters reduce the performance level of vehicles and may cause an engine to overheat.

Overheating

When an engine overheats, many of its parts will expand, and they can warp, bend, and even break if you continue to drive in this condition. Prolonged overheating can fully destroy the engine, rendering it unfixable and useless. As soon as you notice your vehicle’s thermostat needle indicating a high engine temperature you need to take steps to cool the engine. Here are some steps to take provided by reference.com:

Turn off the air conditioner and open the windows to reduce the load on the engine.
Turn on the heater and blower to transfer heat from the engine to the passenger compartment.
If stuck in traffic, rev the engine slightly to increase air and coolant flow through the radiator.

If you see steam coming from the hood you need to pull over immediately. Do not continue to drive your car in this condition.

Revving the Engine

Revving puts unnecessary stress on the engine. It is worse on an engine when it has first been started and is cold with all of the oil still down in the oil pan. The metal parts of the engine haven’t been lubricated yet and revving can cause the parts to wear. Revving repeatedly will eventually damage the engine, potentially costing thousands of dollars in repairs.

Driving Before the Engine Warms

Oil doesn’t lubricate the engine well when it is still cold, and the parts of an engine are made to operate in a certain temperature range. After you start your car, wait a minute or two before driving off to allow your engine to have some time to warm. If you start and immediately drive away, you put unnecessary stress on the engine.

Using Only Water in the Radiator

The heat of summer, can cause untreated water to reach its boiling point quickly, causing the engine to overheat. And, in the winter, if the untreated water freezes, it can expand and crack your engine block. It is safest for your vehicle to use a 50/50 mix of coolant and water.

Driving Through Water

If you drive through large, deep, puddles of water, you run the risk of some water being sucked into your engine’s cylinders. Cylinders contain air and fuel droplets that compress so when the pistons squeeze, the pressure goes up. Water does not compress, so when the piston tries to squeeze it, it cannot do so. If this happens parts that are connected to the piston can break or bend, resulting in expensive repairs.

Ignoring the Check Engine Light

It is often mistakenly believed that the Check Engine light isn’t serious and can be ignored. Though it doesn’t always signal immediate danger, it does indicate that there is something wrong with the engine. It could start out as something minor, but left unchecked can turn into something major and costly.

Having regular maintenance done on your vehicle -following the schedule recommended in your owner’s manual- is the best thing you can do to keep your engine performing efficiently and smoothly. If you are due for regular maintenance or have any concerns with your vehicle, call Virginia Auto Service, (602) 266-0200. We are happy to help.

How to Identify the 6 Common Fluids That Leak from Your Vehicle

You pull out of your parking spot and you see it, a puddle of fluid has built up under your car. This is not a good feeling. Thankfully, with a little know how, you can easily determine if these spots are a harmless leak, or something that you should have fixed right away.

Analyzing the location, color, and consistency of the spot will help you determine the cause and severity of your leak problem. There are six fluids that are the usual leak suspects.

Engine Oil

Light Brown to Black with Medium Consistency

Due to the many gaskets and seals where a drop can seep out, spotting a little bit of this amber-to-brown/blackish fluid is probably not a big deal. However, if the spots are frequent or are becoming larger, it’s probably a good idea to track down the origin and have it fixed before a tiny leak becomes a big issue. Have your vehicle looked at right away if you initially found a larger spot as this could be a sign of a serious issue.

Transmission Fluid

Reddish and Thin or Brown and Thick

These stains, drips, or puddles may look similar to engine oil leaks, but are usually thicker and are located near the center of the car. Some newer model vehicles transmission fluids are thinner, but easy to identify due to their reddish color. Transmission leaks should be looked at right away as they are most likely coming from a failing gasket or seal.

Power Steering Fluid

Reddish or Light Brown and Thin

Because transmission fluid can also be reddish and thin, you may be thinking that you will get these two confused. However, they can be identified easily based on their location. The power steering fluid will be found near the front of your vehicle, whereas transmission fluid will be located at the center of the vehicle.

Coolant

Yellow, Pink, or Green and Slimy

Because of its bright colors, coolant is probably the easiest fluid leak to identify. With late model cars, you shouldn’t ever see coolant on the driveway. If you do, this spells trouble and you should have it looked at right away. You could have a leaky water pump or leaking hoses. Failing to check and replace your coolant levels and repairing leaks can leave you stranded and overheating on the side of the road.

Brake Fluid

Clear, Slightly Brown and Slick

Brake fluid is one of the most dangerous leaks to worry about. Have your vehicle looked at right away if you notice a brake fluid leak. New brake fluid will be clear, almost like mineral oil. After time, though, due to dust, rust, and other contaminates it can turn a brownish color. If this is the case, to help distinguish it from other fluids, you will need to remember that it is much more slippery to the touch than transmission fluid or engine oil would be.

Water

Clear, Shiny and Very Thin… it’s water

Have you ever driven to the store and when you come back to your car after shopping notice a puddle of water under the front, passenger side of the vehicle? If so, you had most likely been running the air conditioner. The spot is most likely water that has condensed on the air conditioning hardware and is totally harmless.

If you notice a leak, you should bring your vehicle in for an inspection and repair to avoid causing further, and costlier damage to your vehicle. You should also make sure that before you take any long road trips, you have any leaks looked at and repaired. If you are concerned with your vehicles performance, you can call Virginia Auto Service at 602-266-0200 or schedule an appointment online.
