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

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

They say your vehicle has one, but you've never seen it. And you might not even know it if you stumbled on it accidentally. We're talking about the jack, that tool that allows you to lift one corner of the vehicle up so someone can change a flat tire. So you say you'd never try to change a flat anyway, so you don't care where it is. But one day, you may find yourself in a spot where you're stranded with no cell service and you'll need to at least know the basics of what to do. Well, here's the ironic part. Many of today's vehicles don't even have jacks and spares! Recently, manufacturers have been saving weight by supplying another solution for a flat tire, such as an inflator kit that has a tire sealant in it, or a small compressor. If your vehicle has one of those, it's a good idea to get to know how to use it before you need to use it. Hopefully you'll be able to call roadside assistance and they can take care of things, but circumstances may prev ... read more

Your vehicle is like you in a way. When it gets hot, it needs to be cooled down. And one of the key parts to keeping it cool is the water pump. Now, that's a bit of a misnomer. It IS a pump, but it's pumping coolant, not pure water. Cooling off your engine is vital since it builds up heat when it creates power by burning fuel. Your water pump acts as a way to recirculate that coolant. It goes through a series of tubes and hoses through the engine where it picks up heat, then is sent off to the radiator to get rid of that heat. Cooled off, the coolant is recycled through the water pump to start the journey again. The water pump works by taking mechanical power from the engine, usually from a belt. Obviously, that belt has to be in good condition and adjusted properly or else the water pump won't be able to do its job. Here are some things to look for that will signal problems with your water pump. If your heat gauge is erratic or sho ... read more

Automatic transmissions rule. The old days of shifting your own gears are a thing of the past for most drivers. But automatic transmission trouble can be a big inconvenience for any driver if it comes at the wrong time in the wrong place. Here are some signs to look out for that may mean you are having transmission issues. When you are driving, your vehicle seems to slip in an out of gear without you touching anything. That's what some call, not surprisingly, a "slipping transmission." When your vehicle shifts from one gear to the next, you hear a loud "clunk." Transmissions are supposed to be nearly silent when they shift, so that noise is telling you something is wrong. If you notice there's a puddle of some fluid under your vehicle, your transmission could be leaking fluid. Try to figure out what color it is (try putting a piece of cardboard underneath to capture some of the fluid). If it is red or brown, that's a sign it could be transmissi ... read more

In many places, license plates have to be renewed every year or else you can't drive your vehicle legally. Usually, you'll get a reminder from the agency that issues the plates. That kind of regular attention needs to be paid to your vehicle as well. Its manufacturer has determined a schedule of service items that need to be done regularly, just like renewing your plates. Some depend on time, others depend on distance. A perfect example is oil changes. It's the most important scheduled maintenance you can have done to give your engine its longest life possible. The manufacturer recommends the oil filter be changed at the same time. Here are some more items. Your engine air filter gets dirty and needs adequate air to run most efficiently. The manufacturer recommends an interval for replacing that. Also tires, brake pads, timing belt, oxygen sensor and other items require regular replacement. This is one of the reasons to find a servi ... read more

Most drivers love how easy it is to turn their vehicles, and they have power steering to thank. Engineers have figured out a way to take some of your engine's power to help you turn. Without it, steering can be quite a chore. New power systems are electric, but there are still plenty of the older hydraulic power steering systems out there, and it's wise to keep them working the way they should so you don't find yourself stranded without power steering. Those hydraulic power systems use a fluid under pressure that is pumped to a device that helps you turn your wheels more easily. It's that pressure that presents the challenge. After your vehicle's seen a few years on the road, you may find your steering isn't quite as easy as it was. You may hear a groaning or humming sound when you turn. One component that can fail is the pressure hose that carries that fluid from the power steering pump to that turning assist mechanism. The hose is made of rub ... read more

If you’ve noticed your vehicle is hard to start, stalling, or has lost power, the culprit may be a part with an odd name: the MAF sensor. You may have never even heard of a MAF sensor, but it’s important that it be working correctly, or you may be experiencing some fairly significant engine issues. All vehicles bring in air and direct it through an air filter before it goes into your engine, where it mixes with fuel to provide power to get you going. There’s a tube-like device with a sensor inside it that measures how much of that mass of air is passing through. That’s why it’s called a mass air flow sensor, or MAF sensor. If the MAF sensor isn’t working right, the engine’s computer can’t figure out the right amount of fuel to mix with it, and your engine may hesitate or stall. Sometimes this will cause your Check Engine Light to come on, and any time it does that, make sure you have your vehicle checked by a professiona ... read more

Your vehicle may be wearing boots right now and you might not even know it. They're called ball joint boots. They're actually protective, flexible things that protect parts of your suspension (called ball joints) from all the hazards the road can fling at them. If one of those ball joint boots fails and you don't get it replaced, the ball joints themselves could wind up failing, a repair that can be even more expensive. Ball joint boots not only keep things like rocks, salt, water and dirt out of your ball joints, they also help the ball joints keep their lubrication inside and working properly. To do that, the boots have to be made of a flexible material, sometimes rubber, sometimes a synthetic. They do take a beating, exposed to temperature extremes and debris, and eventually they can tear or crack just because of their age. Unless someone is keeping an eye on your ball joint boots, you may never know there's a problem. That's why when ... 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
