You've probably had your Check Engine Light go on.  Then it goes off and you figure, hey, whatever the problem was, it's gone now and I don't have to worry about it.  Well, the problem may have gone away and it may not have. Your vehicle likely has one of these warning lights on the instrument panel: an amber light that looks like an engine or reads "Check Engine" or "Service Vehicle Soon."  If that light comes on and stays on, it usually means there's something amiss but not urgently in need of service.  (Now if it's blinking, that's another story that we'll deal with in a minute.) Sometimes when it comes on and stays steadily lit, the problem will go away and the light will go out.  Sometimes it will stay on until you get the problem fixed.  Either way, the engine's computer will store a code that can provide clues to what's not working—or wasn't working—the way it's supposed to. If you are just dying to know what that code is, you can buy a ... read more

You notice when your smartphone's battery starts to go weak on you.  It runs out of juice faster than it did when it was new.  Bet you pay attention to that pretty closely. Unfortunately, many of us don't pay the same attention to the battery in our vehicles. If your battery got you through the cold-weather months, you might be thinking you're all set until next winter. But you might be surprised to learn this: Hot weather is harder on a battery than cold weather.  (Note: we're talking about a conventional vehicle here, not an all-electric, plug-in one.) The way your vehicle's battery holds a charge is that it has chemicals inside it, and they react with each other to produce electricity.  A vehicle battery discharges electricity and then needs to be recharged.  Unlike your smartphone that you plug in each night to charge, the way a vehicle's battery gets recharged is by using the mechanical energy of the engine.  It's a pretty cool system that's been arou ... read more

If someone asked you what gas made up the largest portion of the atmosphere, what would you guess? Well, it's not oxygen; it only makes up 20.9 percent.  But since we're talking about oxygen, you should know that your vehicle uses oxygen sensors to make sure your engine is running the way it should. The oxygen sensors measure how much oxygen is in your exhaust.  If there's too much, it means there's a problem with the mixture of fuel and air.  The sensor sends signals to computers in your engine and adjusts the mixture so it maximizes performance and efficiency.  It does this constantly.  Many vehicles have multiple oxygen sensors.  Some have one close to the engine, another close to the muffler.  Two measurements are better than one since they allow readings to be more accurate.  You may have a vehicle with a dual exhaust, so you'd have twice as many oxygen sensors. Your oxygen sensors can fail.  One thing that can damage them is contaminat ... read more

Most of us know a bad muffler when we hear it.  That loud, rumbling sound is unmistakable. Did you also know you can get a ticket for driving around with a loud exhaust system? If your exhaust system has a leak in it, it may be allowing poisonous gases inside your vehicle and could make you seriously ill (or even kill you!) if you breathe too much in. Unfortunately, your exhaust system faces a lot of destructive forces out on the road.  Rust is the worst, and not just in colder climates where they use salt and brine as de-icers.  Exhaust systems can rust from the inside out when moisture condenses inside the pipes.  Vibrations and jolts from rough roads (and the occasional run in with a rock or a curb) can wreak havoc with exhaust systems.  Even a bad oxygen sensor can send too much fuel into the catalytic converter, and the resulting heat can wind up destroying this very expensive component. Your exhaust system is made up of several parts, and all need to be i ... read more

Cold weather can present some real challenges when it comes to your vehicle's windshield.  Think of it.  Your windshield is your window to the world when you're driving, and clear visibility is extraordinarily important for safe travels. So here are 3 tips to ensure that your windshield can do its job during the cold weather. Don't ever pour hot water on a frozen windshield.  Let's say you head outside and see your vehicle covered with ice. You think, hey, maybe I can heat up a pot of water on the stove and melt that off fast.  Don't do it!  You run the risk of shattering the glass the second that hot water hits the frigid glass.  Ditto for using a propane torch.  Glass does not do well with sudden temperature changes.  Instead, turn on your engine and start the defroster, which heats the windshield up gradually.  Use a plastic scraper designed for windshields (don't EVER use metal to scrape) and be patient.  Don't hammer on the ice to ... read more

Distracted driving is bad, you know that.  Daydreaming, talking on the cell phone, putting your makeup on in the rear view mirror.  All bad.  But there's something else that causes more than twice as many accidents, according to a recent study.  And that's people who don't use their turn signals.  Maybe you're one of them.  One survey said nearly a quarter of drivers were just too lazy to use their turn signals.  Others said they didn't use them because they weren't really necessary.  Traffic laws may dictate otherwise, but statistics show police don't write that many tickets for turn signal violations.  You may have encountered the driver who cuts into your lane without signaling a change.  Often, that person does it deliberately to catch you off guard so you won't invade his or her space.  And when it comes to young drivers using turn signals, one insurance company survey showed more than two-thirds of those they talked to admitt ... read more

If you park your vehicle outside, you are exposing it to all sorts of critters that would love to use it for nesting, food storage and shelter.  There are plenty of pictures online of people who've discovered there was more than an engine under the hood.  In one case, the driver of an SUV started to smell a slight burning odor when she was driving.  Turned out to be 200 walnuts and a lot of grass had been stored there by some industrious squirrels preparing for the upcoming cold weather.  The SUV owners had their vehicle inspected not long before this happened, but it doesn't take some animals long to set up house in what they think is the ideal spot to make their winter home.   Obviously, that can create problems.  Squirrels, mice, rats and other small animals can chew through hoses and wires.  Plus what they store as food and nesting material may prevent engine parts from moving the way they are supposed to.  Imagine a radiator fan that wo ... read more

In the sloppy cold weather months, you might be tempted to pick up an all-weather mat and throw it on top of the mats you already have in your vehicle. After all, double protection is better, right? In this case, wrong. Here's why. It's important to keep the accelerator and brake pedals clear so they can function the way they are supposed to. Stacking mats in the driver's side footwell can make them sit up too high on the floor. That can, in turn, jam your accelerator pedal forward, causing your vehicle to unintentionally speed up; it may get stuck in that position. Same thing applies to the brake pedal. The mats can get caught underneath it and prevent you from stopping. Here are some other good practices when it comes to mats. It's best to get those designed for your vehicle. They are shaped to fit your specific car, truck, van or SUV. Ill-fitting mats can have the same untended consequences as stacked mats. Good mats will have either a Velcro-type fastener on the back of them or a h ... read more

When you're driving and turn a corner, you probably aren't aware of all that's going on with your wheels.  The outside wheels have a longer distance to travel than the inside wheels, so there are gears that allow the wheels to go at different speeds when you turn.  That set of gears is called a differential.  In front-wheel drive vehicles, it's by the transmission and called a transaxle.  Rear-wheel drive vehicles have the differential, naturally, on the rear axle. Many all-wheel and four-wheel drives add a center differential since power has to go to the front and rear wheels. (Some newer vehicles power wheels with electric motors, but that's a whole different story.) Time and distance traveled eventually can take their toll on the differential, and you may notice some noises you hadn't heard when your vehicle was newer.  Sometimes you'll hear a whir that might change in pitch when you turn.  You may hear clicking sounds when you're moving.  Others d ... read more

Most would agree they'd rather drive around in a clean, shiny vehicle than one coated with a layer of dirt.  When warmer weather comes around, some of us are bound and determined to wash our own vehicles.  And to protect the paint and its luster, there are a few things to keep in mind when you get out the bucket and soap. Cool body.  It's not a good idea to wash a vehicle when the body is hot.  If it's been sitting out in the sun or you've been riding around on a sunny day, make sure you cool your vehicle off by either moving it to the shade or wetting it down with cool water. The problem with washing a hot vehicle is that it's going to dry so fast, minerals in the water can form hard-to-remove spots on the paint.  And some of those can be really difficult to get out.  Best to avoid it. Slippery when wet.  Make sure you wet your vehicle down thoroughly before you get the washing mitt out.  Experts keep a couple of buckets of soapy water on hand ... read more
