Nobody has to tell you that computers are a part of so many things in our lives. Smartphones, kitchen appliances, vacuum cleaners, televisions. You name it—it has a computer in it. And your vehicle is no exception. The earliest cars relied on the technology of their time, and there was no such thing as a computer. But now, it's not unusual for a vehicle to have as many as 150 computers in it. They perform a variety of functions. An important one is diagnosing your vehicle's problems. There are various sensors throughout modern vehicles that measure thousands of data points. When something is not working correctly, they send a signal to another computer that stores that information. The data can be read by someone who has a special computer that plugs into a port in your car. It displays certain codes that help technicians track down the culprit. But it's not just the diagnostics that are computerized. Everything from your vehi ... 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

Things we don't expect happen to our vehicles. And let's face, no one really wants to spend money on an unexpected repair. But if you are putting off going to your vehicle repair facility because you're dreading bad news, you might just be putting off some good news. There was one minivan driver who'd had the same van for years and never had a problem with the power sliding doors. Then one day, the electrical switches in the door pillars stopped working. The key fob would still open them, but the door switches wouldn't do a thing. Of course, the van driver feared the worst: an electrical problem, a major computer failure, mice chewing up the wires. So, he put off going into the repair facility for a couple of months. One day, it was time for his regular oil change and the service advisor asked him if there was anything else going on with the van. The owner mentioned the door problem but said he didn't want to spend a fortune on it. He waited for his van, a ... read more
