When you slow down at stoplight, your vehicle's idle should be smooth as silk. But what happens when the engine is missing or idling roughly? That's your engine's way of telling you, "Hey, I've got something wrong with me and if you don't get someone to find out what it is, I may not start the next time you turn the key." You can help your service facility if you can describe the problem in detail. Here's a list of things to make a note of: When is the problem happening, when the engine is cold or when it's been running for a while? Does the rough idling occur when I'm accelerating or when I'm going at a steady speed? Does it happen at high speeds? Does it happen low speeds? Does it happen at both? Make sure you describe the problem in as much detail because it will help a technician diagnose the problem. One of the first things they'll check is how the spark plugs are firing. Modern iridium plugs are supposed to last a long, long time. But they CAN even ... 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

You probably have heard that expression, "A stitch in time saves nine." In other words, if you fix an issue at its early stages, it will prevent a much more difficult problem later. That's certainly the case with your vehicle, and here's a true story to demonstrate it. A driver noticed his vehicle was due for an oil change, so he took it in to his service facility early in the morning so he could wait while the work was performed. The technician routinely checks the battery on vehicles just before extreme weather is approaching (cold or hot), so with winter coming up, he hooked up the load tester (it measures voltage while a load is put on the battery). It showed the battery wasn't holding a charge well. The technician checked the manufacturing date on the battery, too (most batteries have a date stamped in code somewhere on them). The date showed it was five years old. While batteries can last more than five years, many technicians say you should expect to get anywhere from three to s ... read more

When the weather turns cold, it's nice to crank up the furnace and enjoy the heat. But if your home's furnace doesn't work, it's not too comfortable. Same goes with your vehicle. When the heater's not working, things can get miserable. It could also signal some major problems, which we'll discuss later. A vehicle's heating system is fairly complicated. It's made up of several parts, including a blower motor/fan, a heater core and some mechanical and electrical components. In basic terms, a vehicle's engine warms up coolant which is then sent to the heater core (which is kind of like a small radiator) behind the dash. That blower motor sends cold air through the heater core which heats up the air. Voila! Heat. Diagnosing problems in this system takes a trained mechanic because of the different possible issues. Your heater core may need replacing; they are sometimes in tight spots and may be difficult to work on. Another possible problem could be a defective thermostat, which regulates h ... 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

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

You've heard that expression, change is good. When it comes to your vehicle's oil, change is not only good, it's vital for the health of the engine. But there's one question that puzzles many drivers: how frequently should my vehicle's oil be changed? There is not one simple answer, but here are some guidelines that will help. It used to be pretty much a rule of thumb that vehicles got their oil changed once every 3 months or 3,000 miles/5,000 kilometers. But times have changed. Oil formulations have gotten better and engine designs have made longer oil change intervals possible. Most experts advise you to read the recommendations that come from the manufacturer that designed and built your vehicle. Their designers and engineers know more about your vehicle than anyone else. They spell out their recommended oil change interval and type of oil in your owner's manual. Many automakers say you can go at least 5,000 miles/8,000 kilometers betw ... read more

Some people love 4x4 vehicles, the true 4-wheel drive works of engineering like Jeeps and 4x4 pickups that allow you to seemingly go anywhere on the planet. You can climb up a 40-degree rock trail with some planning and skill (always careful to protect the environment, of course), or you can get through the deepest snow. But with that added capability comes additional complexity, drive-train components and other systems that less capable vehicles don't have. And that is why when it comes to 4x4s, you have to maintain them a little differently from those vehicles that spend their lives on pavement. Here are some of the key things to keep an eye on: Transfer case—This transfers power from the engine to the wheels. A transfer case has fluid in it that needs to be changed at intervals recommended by the manufacturer. Your service advisor will let you know how often that is and will keep track of your service dates. You will need to make sure the transfe ... read more

A technician was telling us the other day that he was servicing an engine and spotted something he'd never seen before: A collection of dry dog food siting on a horizontal metal ledge near the base of the engine. It was neatly stashed and was in a spot where the food pellets couldn't have simply fallen down in there. Even though it's the first time he'd seen dog food in an engine, he immediately knew what was going on. Critters like mice or chipmunks had found the dog food somewhere nearby and had used the engine as a nice storage unit. Mice, squirrels, chipmunks—you name it—like the heat of the engine. And they'll use that to store up supplies of food for use in cold weather when outside food supplies are scarce. The problem is they'll also chew on engine components while they're there. And they can do a lot of damage if they start gnawing on the wires. Depending on how much of your electrical system needs to be replaced, repairs can mou ... read more

You swap your winter boots for flip-flops in the summer. Why not change your winter engine oil for summer, hot-weather oil? While it may seem like it makes sense, there's some good news. Most drivers don't have to, and here's why. Engine oil can be made in different thicknesses. That thickness is called viscosity, how easily it flows. Now, it makes sense that the hotter it gets, oil gets a little thinner and doesn't lubricate as well. So if you used a thicker oil in the summer, it's logical that it would protect better in the hotter weather. While there was a time when oils could be only made in one viscosity, times have changed. Using an ingenious formula, oil can now be created that changes its viscosity (called "multi-viscosity") as the temperature rises and falls. It self-adjusts to match the conditions. Now that's what I call a great invention. In most temperate climates, you don't have to swap out the type of oil you use ... read more
