Your gasoline engine goes through some exhausting work. Yes, it's truly exhausting, as in: it produces exhaust! And when your engine starts behaving like it's exhausted, such as running poorly or getting lousy fuel economy, the trouble may be something called a PCV valve. Did you know it's a series of explosions that creates the power in your engine? The spark plugs ignite a mixture of gasoline and air and BANG! A whole bunch of those and you're engine is humming away. Leftover vapors from those explosions go into your crankcase, which is also a place where engine oil goes. Those vapors still have a lot of unburned fuel in them, and if they had nowhere to go, they'd turn your oil into a thick mess called sludge, not good for a smooth running engine. Engineers came up with an idea. Re-direct those gasses building up in the crankcase into the engine's air intake and mix them with fresh air. That way the unburned fuel could go through the engine again and produce p ... read more

It's bad enough when you mistakenly leave a window open in your vehicle on a rainy day and you find your carpet soaked. But what in the world is going on when your windows are closed tight, not leaking and you STILL wind up with wet carpet? The answer could be something you might not even know your vehicle has. And the answer is? Drains. And those drains can get clogged. Yes, your vehicle has several drains with tubes or hoses attached to them that you really never see. There are some in and around the hood that channel rainwater down to the ground. There are some that take condensation from the air conditioner and allow it to flow outside. And if your vehicle has a retractable sunroof or moon roof, there are small drains at each corner that connect to tubes that go through the vehicle body down to an exit near the ground. Considering all the leaves, dirt, dust and other debris your vehicle encounters on a daily basis, it's not surprising that these ... read more

You’ve probably already heard that regular oil changes are extremely important for the health of your vehicle’s engine. That’s sound advice. But what you might not know is when it comes to motor oil, the real thing may not be the best thing for your engine. There are different types of motor oil: Conventional oil, extracted from the ground and refined. Synthetic oil, manufactured from high-quality base oils and artificially-made chemical compounds. Synthetic oil blend, a mixture of conventional and synthetic oils. The first thing you need to know is that most new engines require synthetic oil. If synthetic oil is recommended for your car – you MUST use it. For the rest, there are many advantages to using synthetic oil over conventional oil. Synthetic oil provides better protection for your engine while helping it to perform better. Conventional oil breaks down over time, while synthetic oil lasts longer. Synthetics can stand higher temperature ext ... read more

Ever wonder what one of the best things is to ever happen to your vehicle's engine? It's the little thing that usually looks like a can, the oil filter. Just like your kitchen sink strainer filters out errant particles of food from clogging your drain, the oil filter cleans out small particles that could cause your engine harm. Your engine operates in a dirty, hot environment and gathers a lot of tiny contaminants like dirt, dust, little metal shards and unlucky bugs that get sucked in. Get those things circulating in your engine and those little particles can cause friction, which starts wearing out those finely machined metal parts. You know how important it is to change your oil regularly. It's vital that you change your oil filter at the same time to keep the oil as close to brand new as possible. Most oil filters look like a metal can with some holes in the bottom. Inside there are carefully chosen materials that can screen out the contaminants while ... read more

When you turn on the air conditioning in your vehicle, you expect cool air to come out of the vents. You depend on it, especially in hot weather, but it can also be important in humid weather when you need it to help defrost your windows and windshield. The air conditioning system has a lot of parts to it. It has fans and blowers to move the air through the vents into the cabin. It has parts that take hot air and cool it off. An electrical problem can be as simple as a broken switch or a broken blower motor. The air may not be getting cool because a hose in the system is broken or the refrigerant has leaked out. Two major components are the compressor and the condenser. The compressor pressurizes the refrigerant, one step in the air conditioning process. The condenser takes that hot refrigerant and cools it down. It also reduces the pressure. Because the climate control system in your vehicle is so complex, it’s best to leave the diagnosis to a ... read more

If you've ever walked into your garage and noticed it smelled like gasoline, pay attention. Gasoline can be dangerous, both from the health problems fumes can cause and the fire danger gasoline presents. There are many things that can cause a vehicle to give off a gasoline odor. One of the easiest to track down is the gas cap. It could be missing or it doesn't seal well any more (they do wear out). That can also cause the Check Engine light to light up, so those are clues to tell your service advisor when you take it in for diagnosis. Another thing that can cause the Check Engine light to come on and produce a gasoline smell is the fuel filler neck. It's the part that goes from the place you put your fuel in to the gas tank. Over time, these can wear out and fail (they're made out of rubber or metal). They can leak gasoline, too. It's always a good idea to check the garage floor for any gasoline puddles. Note the location of the puddle in relation to ... read more

If every road was straight and smooth, we wouldn't have to worry much about wheel alignment. But they're not, so we do. Hitting potholes or driving on rough pavement can knock your vehicle out of alignment and you'll notice it in one of several ways. Your steering wheel may not be centered when you're driving straight ahead, or your vehicle may pull to one side. You may find your tires wearing on one side or they may squeal. All are signs that could point to you needing an alignment. Your wheels should be perpendicular to the road and parallel with each other. If not, your tires will wear out faster and your vehicle won't go straight on a level straightaway. In alignment, there are several factors that must be checked. One is camber. Your wheels should be straight up and down if you look at them from the front. If not, you'll wear your tires unevenly on one side. Another factor is caster, the angle of the steering pivot. Most vehicles have what ... read more

Synthetic motor oil has been around for a long time, and more and more new vehicles are leaving factories with synthetic in their engines. But a lot of drivers don't really know much about it.Let's start with conventional oil – the kind folks are used to. Conventional oil is made up of naturally occurring hydrocarbon chains, which means its molecules are long and have various lengths. Like a pile of pencils, some of them new and some of them used.Synthetic oil is man-made. Its molecules are more uniform and regular in shape – more similar to marbles than pencils. Some synthetic oil starts with a petroleum base that's modified and others are entirely synthesized from other materials.Synthetic motor oil works better in both hot and cold temperatures. It's more chemically stable so it doesn't readily evaporate or break down in the high heat produced inside your vehicle engine. This means it resists turning to sludge, which is a real engine killer.Remember that marbles and ... read more

You are heading down a flat, newly paved street when all of a sudden you feel it. Your vehicle jumps a little bit when you're accelerating and changing gears. You know it's not the surface of the road because it's smooth as silk. So what did you just feel? That kind of jumping—or grinding or slipping—during gear changes could be a sign of trouble in your automatic transmission. And it's important to get it checked out fairly soon because some transmission problems that aren't fixed early can lead to more involved and expensive repairs. By far most vehicles on the road in North America have automatic transmissions, and they are workhorses. Unlike early cars with balky, hard-to-shift manual transmissions, the latest automatics allow you to drive without having to even think about gear changes. But you should know about a few signs of trouble to look for if they ever start showing up. When you first get going and shift your vehicle from Par ... read more

If you've ever felt your vehicle hesitate, go, then hesitate again, you might think there's something wrong with the transmission. After all, it's not moving smoothly down the road. But there are plenty of malfunctions that can cause those symptoms, one of them being something you may have never heard of: the EGR valve. EGR stands for Exhaust Gas Recirculation. It's a system that channels small amounts of exhaust back into the engine to cool down the cylinders and reduce polluting gases. Those include nitrogen oxides that can cause smog. The EGR valve regulates how much of the vehicle's exhaust gas is recirculated. After years and long distances traveled, that valve can get clogged or fail. Sometimes the EGR valve can stick open. When the EGR valve isn't working properly, your vehicle can start releasing those nitrogen oxides and pollute the air. The symptoms of a malfunctioning EGR valve include: Engine losing power Engine idling roughly Pinging and knoc ... read more
