You may have had a friend whose vehicle was the victim of hungry rodents. After all, mice, rats and squirrels—even rabbits—have been known to gnaw on wires in engine compartments, causing vehicle electrical systems to go haywire. They can disable a vehicle completely and be very expensive to fix. In 2017, some drivers noticed their vehicle's wiring was being chewed and found out the automaker was using a relatively new material for covering their wires: soy. Many of the repairs to their new vehicles weren't covered under warranty by the manufacturer when it was discovered rodents were eating the wiring. So the owners filed a class action suit, saying the soy covering was essentially baiting the critters. The automakers tell a different story, saying mice, rats and squirrels have been chewing through wire insulation long before it was made out of soy. Regardless of what the insulation is made of, vehicle owners should make sure rodents are ... 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

When it comes to your vehicle, driving it too much can cause some issues. But what about not driving a vehicle enough? That has consequences as well. Here are a few things that can happen if a vehicle isn't driven enough. When the engine doesn't operate, the oil isn't lubricating. That means some mechanisms that need periodic lubrication aren't getting it. And oil that sits around breaks down over time. In fact, some experts say you should change oil more often if your vehicle sits in the driveway than if you drive it regularly. You've heard that expression, "Take it on the highway and blow out the engine.” Well, carbon buildup used to be a problem in older vehicles. But the real culprit these days is moisture that builds up from combustion if your vehicle never gets hot enough to burn it off. That water vapor can mix with oil and cause sludge to form. There are many vehicle systems (battery, exhaust system, engine seals, etc.) that benefit fro ... 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 may remember a song that went, "Objects in the rearview mirror may appear closer than they are." While that was a song about life's lessons, there are a few things we should all know about how important rearview mirrors are to safe driving. While new electronic devices are helping drivers be aware of surrounding traffic in high-tech ways, the good old rearview mirror is still a dependable way of letting you know what's around you. There are usually 3 on each vehicle, 1 attached to the windshield inside and 2 attached outside on each of the front doors. It's important that they be adjusted properly before you start driving (not while you're driving). Experts say the windshield rearview mirror should cover the area behind the vehicle while the outside mirrors should not simply duplicate that view but extend it to the sides, where blind spots normally are. Your rearview mirrors must be able to hold the positions they're adjusted in; it there's play in them or they move around, y ... 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

Here's a part of your vehicle you probably don't think about much: lug nuts. They're what fasten your wheels onto your axles. Pretty important, right? In order to take the wheels off your vehicle to service the brakes, rotate the tires, etc., the lug nuts have to be in good shape so a wrench will grip them tightly. Because lug nuts are on your wheels, they are exposed to all the elements of the road (salt, water, grime) and really take a beating. Unfortunately, some manufacturers have made them out of two different metals. Underneath is the working part of the lug nut, made of steel. On top is the decorative (the "good looking") part, made out of chrome, stainless steel or aluminum. After a while, the steel part begins to corrode and expands. That changes the shape of the outer cap, sometimes rounding off the hexagonal edges and making it hard (if not impossible) to either loosen or tighten the lug nuts since the wrench won't fit any more.  ... read more

It's no fun when your vehicle just doesn't run the way it used to. You may notice (especially in cold weather) the engine won't start easily or when it does start, it doesn't run smoothly. It may not have much power at all. You also may have had to stop at the gas station more often, a sign your fuel economy isn't what it used to be. There could be a few different things that cause those symptoms, but one culprit could be a bad ignition coil. The coil takes the voltage from your battery and multiplies it before that power is sent over to a spark plug. That allows the plug to fire off a good jolt of electricity that ignites the fuel in your cylinder and powers the engine. There's usually one ignition coil for each cylinder (or sometimes for a pair of cylinders). If only one of them is not pushing out enough electricity, it can cause big trouble with your engine performance. Other signs of a bad ignition coil include engine backfire, an oil leak and your Che ... read more

When you start up your gasoline engine car, you may not know that it's using the same ignition principles as it has for decades. You have spark plugs that require enough power so a spark can jump across a gap at its tip. Years ago, a vehicle's 12-volt system had to produce 15,000-25,000 volts to do that, so engineers came up with something called an ignition coil that bumps up the voltage. It also has to be done at just the right interval called timing. The first systems had a distributor, a mechanical device with a rotating disc that switched the power to the ignition coil on and off. That higher voltage then was sent to the spark plugs at the correct time interval. But the mechanical "points" had to be replaced and adjusted every 12,000 miles/20,000 kilometers. Engineers later replaced the switching mechanism with solid state ones, but they still needed replacement after 120,000 miles/200,000 kilometers. The next evolution came in the 80's when the distributor ... 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
