Vehicle emission testing has become ubiquitous in North America and for a good reason. Clean air quality is important for the environment and all of us. Since vehicle emissions are among the main causes of air pollution, emission testing can alert you to problems in your vehicle than can be fixed so it won't needlessly pollute. Emissions tests are looking for certain toxic gases internal combustion engines produce, such as nitrogen oxide, particulate matter, non-methane organic gases and formaldehyde. Emissions control systems reduce these gases if they are working properly. The best way to minimize pollution is to keep those vehicle systems working properly, and periodic inspection and maintenance is the key. So if you want to make sure your vehicle will pass an emissions test, it helps to know what might go wrong. Let's start on the easy one. Your gas cap could be loose, allowing vapors to escape into the atmosphere. The most common solution ... read more

We've all seen drivers who do things that—let's be frank—really irritate us. They're inconsiderate, can put people in danger and make the road a much less friendly place. They really "T" us off. These are the bad drivers who fit their description to a "T." The Tailgater. You've seen this terrible driver who follows a few inches off the bumper of the vehicle ahead. We all know what's going to happen if the driver ahead of the tailgater has to slam on the brakes. And we've all been that driver followed by the tailgater, whose vehicle fills up your entire rearview mirror. The tailgater is likely not in a great frame of mind and, thanks to his or her stupid driving practices, the "tailgatee" is getting pretty ticked off as well. That's a formula for a big problem. Know anybody who respects or likes a tailgater? Didn't think so The Texter. All sorts of people think they are perfectly capable of texting while driving. I ... read more

At one time or another, most drivers honk their horn at someone who might be texting at a stoplight or not paying attention when they're driving. But what happens when you tap on your horn and all of a sudden it won't quit? Everyone's looking at you like you're an angry jerk and all you want to do is turn it off! It helps to know the basics of what's happening when you honk your horn. There's a switch in the steering wheel, of course, and when you press on it, it sends power to a relay which then energizes the horn. Bingo. Sound. When the horn sticks on, one of these parts or the wiring has developed a problem. With the ear-splitting noise inside your cabin, it may be hard to keep your cool, but do your best to stay calm. Try pushing the horn several times; it may un-stick the switch if you're lucky. If not, there are a couple of things you can try. First, if you can, pull your vehicle off the road and into a spot where you're not disrupt ... read more

A technician was telling us the other day that he was servicing an engine and spotted something he'd never seen before: A collection of dry dog food siting on a horizontal metal ledge near the base of the engine. It was neatly stashed and was in a spot where the food pellets couldn't have simply fallen down in there. Even though it's the first time he'd seen dog food in an engine, he immediately knew what was going on. Critters like mice or chipmunks had found the dog food somewhere nearby and had used the engine as a nice storage unit. Mice, squirrels, chipmunks—you name it—like the heat of the engine. And they'll use that to store up supplies of food for use in cold weather when outside food supplies are scarce. The problem is they'll also chew on engine components while they're there. And they can do a lot of damage if they start gnawing on the wires. Depending on how much of your electrical system needs to be replaced, repairs can mou ... read more

No one likes to be greeted in the morning by having someone screech at you. The same goes for a loud, high-pitched noise your vehicle greets you with every time you start the engine. If you're wondering if that's normal, no, it isn't. And it is worth getting checked out. The good news is that it might be nothing serious. Then again, it may be. The first things to suspect any time you hear a high-pitched sound coming from the engine are belts. They have tension on them and they're trying to turn lots of different pulleys, pumps and other equipment the engine needs to work properly. The noise could come from the belts starting to wear out and dry out. If one of those belts breaks at an inopportune time, not only can it strand you somewhere, the damage to the engine could be very expensive to fix. Other things that will cause a high-pitched sound are the pulleys and tensioners. The tensioners keep the right amount of pressure on the belts an ... read more

Engines required a lot more maintenance in earlier times. You'd have to have your spark plugs, wires, rotors, caps, distributor points, fuel and air filters changed periodically. There were mechanical adjustments of a vehicle's timing, dwell, spark gap and idle mixture, too. Unless you like to tinker with old cars, a lot of those terms won't mean much to you. That service was called a "tune up" back then, and you can see why. But now, computers have reduced the number of maintenance items, and a tune up is a whole lot different than it used to be. In fact, in some vehicle service facilities, that term is also a thing of the past. A tune up of today would more accurately be called simply periodic maintenance. Now, most vehicles still have spark plugs and wires, fuel filters, air filters and PCV valves, and they should be inspected tested and/or replaced at regular intervals. Your vehicle's manufacturer has made recommendations on how often that ... read more

You probably never thought about it, but your vehicle is like a rolling weather station. It can check the outside temperature, let you know when the roads are slippery and help you deal with rain. And how it does all those things is pretty cool. First, just like any weather station, a vehicle has sensors that measure the driving and weather conditions you find yourself in. Some of those sensors can control computerized systems in your vehicle to react to the weather. It depends on whether you have a 2-wheel, 4-wheel or all-wheel drive vehicle how those sensors will respond. Let's start with temperature. Most vehicles now have a thermometer that measures the temperature outside. It's usually in the front, and likely will tell you on the instrument panel what the outside temperature measures. But a temperature sensor will also tell your vehicle's computers to turn on or off certain systems like the heating or air conditioning. If your ambient tem ... read more

When someone mentions driving like a maniac, they're not talking about you, surely? Besides the safety issues of aggressive driving, you should know that your vehicle will last a lot longer if you'll just mellow out a little. Here are four traits good drivers follow if they want their vehicles to go the extra distance. Cool—The driver who can't wait to get to the next stoplight is just shortening the life of his or her vehicle. Jackrabbit starts and uneven acceleration hurts your engine because the valves and cylinder heads are stressed more. All of those moving parts will wear out faster as well as other components that are connected. That means things like the air conditioner, power steering pump… just about anything that attaches by a belt or a pulley. Oh, and you'll be generating more heat. Heat is one of a vehicle's worst enemies. Warm—If you get in your cold vehicle which has been sitting overnight, start it up and rev the en ... read more

Let's face it. Vehicles are complicated machines, each having thousands of parts. And since they're subjected to heat, cold, vibrations, bumps and much more, these parts wear out and need to be replaced. When your service advisor says you need a new part, you may have many options. Let's say you need a new muffler. One choice would be to get exactly the same part that was installed when the vehicle was manufactured. The advantages are that it will perform the same way as the one it's replacing and will likely last about the same amount of time as the original. Some mufflers are made by the same companies that supplied the automaker when your vehicle was new (they call that an OEM part—Original Equipment Manufacturer). And often those are the same as the part you'd buy from a dealer. A reputable vehicle service facility will know which ones these are because they replace mufflers all the time and do their homework. The good news is there a ... read more

You may have heard at one time or another about something called a timing belt or timing chain in your engine. And you may know that if they fail… well, let's just say that there can be some major engine damage. So obviously, we want our timing belts and chains to be in tip-top shape. One part that helps keep them running the way they should is the timing cover. As you can probably guess, it's something that covers the belt or chain. The timing cover protects both belts and chains from dirt and road debris. Timing belts also need to be lubricated so their covers allow them to be lubricated as well. They have a gasket that insures a good seal for the engine. If that gasket breaks or develops a leak, then engine oil can escape, and loss of lubrication is never good for an engine component. Other symptoms of a failed timing cover are leaking coolant, a metallic sound coming from the front of your engine or your Check Engine light coming on ... read more
