When the weather gets colder, sometimes the noises your vehicle makes will change. For example, you may notice a whining sound when you get going in the morning. It may go away when the vehicle warms up, but it's best not to ignore that sound because it could be a warning of worse things to come. Colder temperatures cause different components to behave differently. Let's take a look at a few of them. First, the fluids in your vehicle. Cold temperatures can make them behave a little differently, such as engine oil, transmission fluid and power steering fluid. Those characteristics could change if the fluids are older and full of contaminants. Belts also can create a whining noise when cold. Since they turn pulleys that move other things, several factors can create issues. Increased friction can change proper tensions on belts. Plus, belts change as they age and may crack, get loose or develop a glazed surface. Belts and pulleys also must b ... read more

Alfred Hitchcock once made a mystery thriller film called "Rear Window." It had nothing to do with the rear window of today's cars, SUVs, CUVs and light trucks. But there is one thing that some drivers DO find mysterious. Why don't the rear windows in the second row of many of these vehicles go down all the way? You've probably seen or owned one or two. That rear side window only goes down about a third, a half or three-quarters of the way. Yet there are some similar vehicles where the window goes down all the way. What gives? There was the rumor going around that the restriction on how far those windows could go down was a child safety feature. The thought was that if those windows couldn't open up fully, a child (or pet) would be less likely to fall out. But it turns out the real reason is that the way the rear doors were designed, there was just no room for the window to go down all the way into. Many vehicles are configured so that the rear wheel arch ... read more

Ever notice a little spot of liquid under your vehicle after you've parked in your driveway or garage? It may have been something as simple as water left from air conditioning condensation. But then again, it could be a sign that there's trouble brewing in one of your vehicle's systems. You can help your service facility diagnose the problem by getting a little sample of the drip. At the same time, you may save yourself a tougher clean up task by preventing the leaky fluid from really messing up the driveway or garage floor. The first thing is to put something under the vehicle. A flattened out cardboard box will do fine. You may also want to slip a little disposable aluminum tray or pan under it to catch a bit of the fluid. Chroma and consistency can help a technician quickly figure out what kind of fluid you're dealing with. You can take your sample with you when you go to your service facility. Also note how much of the substance is there over wha ... 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

When the temperatures plunge, your vehicle better be ready because it faces a whole new set of challenges. Rubber stiffens, glass fogs, fluids freeze. Just thinking about it can get your heart beating faster. So here are some tips for getting ready for those inevitable colder temperatures. Make sure your tires are in good shape and properly inflated. Traction can be less than ideal on slippery streets, so your tires must have enough tread to grip the road. They should also be inflated properly, and inflation will change as the temperatures go down. One last thing on tires. Do you know how old yours are? They actually have a birthdate printed on them. Old rubber can compromise drivability and handling. Some tires look great but their rubber doesn't handle stresses like it used to. Have your vehicle service facility inspect all of these aspects of your tires so you are riding on tires that are fit to go. Anyone who lives in an area where th ... read more

More and more of us are hanging on to our vehicles longer. A company by the name of HIS Markit recently released a report that shows the average age of light vehicles in the U.S. is now 11.8 years. Light vehicles are cars, SUVs (sport utility vehicles) and CUVs (compact utility vehicles). In Canada, the average life expectancy of a vehicle there is around 13 years, and in the U.S., it's around 15. Vehicles are lasting longer these days, and there are several reasons for that. One expert cites better technology and overall quality improvements. While in past years, vehicles were made mainly of heavier steel components, more modern vehicles contain lighter magnesium and aluminum alloys, high-strength steel, polymers and carbon fiber. They last longer and reduce the overall vehicle weight, and that can contribute to better fuel economy. Modern internal combustion engine designs have been improved, and since they use more computers, they are more efficie ... read more

When you feel your vehicle vibrating as you're driving down the road, one cause could be something you may not have ever seen: your driveshaft. It is underneath the vehicle and most drivers don't climb under there to take a look very often. The driveshaft is a cylindrical part that helps conduct the rotational power from your engine to your drive wheels. If you have a four-wheel drive vehicle, you may have two driveshafts. The drive shaft has bushings, and when they wear out, that's a likely source of the vibrations. When the bushings are in good condition, they prevent the driveshaft from vibrating. And if you don't get your vehicle repaired fairly soon after discovering vibrations, they'll continue to get worse and cause other components of the drivetrain to wear out. The driveshaft is, of course, only one part of the drivetrain. It includes other parts such as axles, transmission, differentials and joints. They all work together and ne ... read more

Would you buy a jacket without even trying it on? Probably not, but it might surprise you that one study shows about half the people buy a vehicle after a short test drive around the block or none at all. If you're in the market for another vehicle, make sure you check out the most important things so you'll know if that's the right vehicle for you. Check out the gadgets. Love a good sound system? Then turn it up loud. Does it have enough bass for you? See how you like its navigation system if it has one. Try pairing your Bluetooth smartphone with the vehicle. Test out how to set the cruise control and how steady it keeps the speed. Back up and check out the rearview camera. If you buy this vehicle, you'll have to live with all of these things every time you drive. Test the vehicle on roads you know. See how it handles bumps and potholes, how it takes that tight curve that you drive every day to and from work. Driving on familiar roads gives yo ... read more

So your vehicle won't start. What's the first thing that comes to mind? Battery dead? Starter motor worn out? Out of gas? Well, those are all reasons that make sense. But your vehicle may be refusing to start because one of its computers is being warned that to do so might damage it. Here's how that works. You have lots of computers in your vehicle. They need to know the status of things so there are several sensors monitoring various things going on. These sensors send information to the computers that adjust the fuel and air mixture so you don't waste fuel. They know when things aren't quite right and prevent you from starting your engine if that's going to damage it. Other sensors make sure the coolant is the right temperature, check to see you are not polluting the air and make sure other electronic components are performing their tasks correctly. Here's an example of a sensor doing its job. Your engine needs oil to lubric ... read more

If you hit a bump in the road and your vehicle just keeps bouncing up and down for a lot longer time than it used to, you may have bad struts and shocks. They're the things that help to keep your vehicle's wheels and tires planted to the road surface. But they don't last forever. With care and depending on where and how you drive, shocks and struts should be replaced at intervals ranging from 50,000 miles/80,000 km to 100,000 miles/160,000 km. If you drive on bumpy roads with a lot of potholes, that interval will likely be shorter. Rough surfaces can take their toll. But how do you know if your shocks and struts are doing their job properly? The best way is to have your vehicle checked by a technician. He or she can inspect the shock absorbers and struts for leaks, corrosion and damage. Mounts and bushings can also go bad and they should be evaluated as well. A thorough examination by a technician will also include looking at other suspension parts ... read more
