Driving along, your exhaust system's rumbling so loud that people turn and stare at you pass by. You're wondering when the police are going to pull you over for illegal noise. Your mind immediately thinks, aha! A broken muffler. Well, your exhaust system is composed of many more parts than just a muffler. Your engine makes power because of thousands of tiny explosions from detonating fuel. Those explosions make a racket, so engineers came up with a system that acoustically dampens that sound in addition to getting rid of harmful exhaust. In the engine is the exhaust manifold that looks like several pipes that join up into one pipe. It directs exhaust to the catalytic converter. The catalytic converter converts harmful gases into less harmful gases using certain chemical reactions. Then comes the muffler that has baffles inside to quiet the sounds of your engine noise. Finally: the tailpipe. All of those pipes and parts are joined together by cl ... read more

As the temperatures plunge, certain types of engine oil may not flow as easily as they did when it was warmer. Makes sense, doesn't it? Just like molasses gets thicker as the temperature goes down, engine oil does the same thing. So, maybe you're wondering if you have to change your oil as the seasons change so it's just the right thickness to lubricate your engine parts. How well engine oil flows is called its viscosity. There are different types of oil—some that have just one viscosity and others called "multigrade" oils. Here's the difference. A single viscosity oil will flow better when it's hot but not as well when it's cold. A multigrade oil is engineered so that its flow properties at cold temperatures are different than they are at warm temperatures. In other words, a multigrade oil can start out in colder temperatures acting like a thinner oil and then behave like a thicker oil when it's warm. That's a pretty cool trick and it's why mu ... 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

If you've ever had a flat tire, then you know welcome it is to have a spare tire that is properly inflated, in good shape and easy to get to. Problem is many of us don't even give our spare tire (if we even have one) a second thought. If you have an SUV or truck with a spare, it may be mounted outside the vehicle, such as on the tailgate or underneath the vehicle. All of them, especially those underneath, take the brunt of debris, moisture, salt and dirt from the road surface, a potpourri of corrosion potential. The hardware that holds these on can rust into a solid mess, making it hard for you or even a roadside assistance service to get off. If you have one of those, have it checked and maintained at your vehicle repair facility on a regular basis. They should be lubricated and cleaned periodically, and some recommend doing this service every time you have your tires rotated. If the spare is the same size as the tires on the vehicle, it may be a go ... read more

If your vehicle makes a grinding sound when you turn the steering wheel, it's speaking to you. No, really, it is. So listen to what it's saying and you could avoid a much more costly repair down the road. A grinding sound coming from the front of your vehicle when you are turning can offer some very informative clues as to what's going on. One cause could be that there's a problem with the mechanical linkage that enables you to turn the wheels. Another is that the hydraulic system that makes turning the steering wheel easier may have its own problems. Think of it. Hydraulic power steering has many components that need to work in tandem. The power steering fluid may be too old and contaminated. Or its level may be low. That may be caused by a leak somewhere in the system. A technician can check things over to find out exactly what's happening. Other causes of grinding while turning can be problems with the suspension in the front. Yo ... read more

We've all been there. You park your vehicle on a steeper than usual hill and worry about it rolling down while you're running your errands. So you decide you'll use the parking brake. When you get back, you release the parking brake, hit the ignition, put it in gear and—uh, oh—you can feel the parking brake is still on. It's stuck. What do you do now? Welcome to the world of infrequently-used parking brakes. Yes, they do stick for several reasons. It's common for components to corrode and get locked up. Sometimes if you have applied it extra hard, it can jam. Could be a rusty cable, could be a spring that doesn't return the brake to its disengaged position. Some pieces just break when they're stressed for the first time in a while. A caliper or the pivot arm it's on can also stick. There are a few things you can try to unstick it. Carefully rock your vehicle by putting it first in drive and then reverse. You ... read more

So you almost got through the winter until, one day, your muffler started sounding like a dragster, loud and obnoxious. It's not surprising. All that road salt and brine can cause rust to punch holes in a muffler, and that should raise a big, red warning flag about the safety of your vehicle. One big concern is carbon monoxide, a poisonous gas that can drift into your cabin if your muffler is leaking. You've probably heard about people whose home furnaces have leaked carbon monoxide and overcome families inside. Carbon monoxide can first cause you to feel dizzy and nauseous. It can even render you unconscious—even kill you. So if your vehicle's muffler is leaking that gas, well, it's nothing to mess around with. Oh, and how about that noise? You may get a ticket since many municipalities have laws against noisy exhausts. Your muffler may be making a clunking or rattling sound when the engine's running or it may be spewing thick exhaust sm ... read more

Your vehicle may be like that famous battery bunny, the one that just keeps going and going. But while it may seem sometimes like you never need to take your vehicle in to be worked on, there are some things you should keep your eyes, ears and nose out for. They are warning you about something that needs attention at your vehicle service facility. If a warning light is on, don't ignore it; do something about it. There are warning lights for battery, oil, engine heat, tire pressure… you name it. And the manufacturer put them there for a reason. They're telling you something isn't normal. So when one goes on, have it checked out soon, especially the blinking Check Engine light. The earlier you have any warning light issue diagnosed, the more likely you are to avoid a more serious problem. If your vehicle is vibrating or shaking, it's not only annoying, it could signal trouble. You can bet your vehicle didn't do that when it came out of the fact ... 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

You've just arrived at the store shopping and you're ready to head home. You put your key in the ignition and… oh, no! The ignition won't turn! What do you do now? Don't panic. There are some things you can do to get going again. The first thing to do is see if you have a locking steering wheel, an anti-theft feature that was introduced around 1970. Sometimes it sticks. Move the steering wheel side to side while you try to turn the key and you might be able to get it to release. Another thing to check is to see if your vehicle is in gear. Most vehicles will only allow you to start the ignition if it's in park or neutral. If you have an automatic transmission vehicle and it is in park, try jiggling the shift lever and try the key again. Sometimes the safety mechanism doesn't properly make contact or gets a little sloppy. If both of these don't work, it could be your vehicle's battery is dead. Some newer electronic ... read more
