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

Stop! It's one of those things your vehicle has to do consistently and reliably. That's why brake maintenance is vitally important, worthwhile for you to make sure stays up to date. A brake system has many components. If your vehicle has disc brakes, they have pads that make contact with the rotors (the metal discs). Those pads usually have a metal back, and the part that presses against the discs is made of a material which provides friction to stop the vehicle. Because of that friction, the pads are expected to wear down and eventually the rotors will, too. But the pads usually are the part that will need to be replaced more often. But how do you know when it's time? There are several signs, one of which is when your brakes squeak or make a high-pitched sound when you step on the brake pedal. Many newer vehicles also have sensors on the brake pads. When the pads get worn down to a certain point, the sensor will tell the vehicle's computer to turn on a li ... read more

If someone told you that your vehicle could have the same power but with a smaller engine, wouldn't that sound like great idea? Just think, a smaller engine would save you money at the gas station and you'd still get the same horsepower. The technology to do just that has been around for a long time. It's called a turbocharger. Race cars and other performance vehicles have been using turbochargers for years. It gives them a power boost without the need of a bigger engine, saving them fuel and pit stops. Automakers have offered turbo gasoline and diesel engines for years, but there were problems with durability. Plus drivers had to make some driving adjustments with the way turbos delivered power. Newer turbos, though, have been vastly improved, and manufacturers are including them in more models. For example, Jeep offers its 2019 Cherokee with a choice of two engines that each make about 270 horsepower. One is a 4-cylinder turbocharged engine and the other is a 6-cylinder conventional ... read more

Many Wilmot car owners have probably wondered: "What's the harm in putting off replacing an engine air filter? The answer is that not replacing it could cause your Mass Air Flow (MAF) sensor to fail. This expensive sensor is situated between your engine air filter and your engine. Dirty air filters are a leading cause of mass air flow sensor failure – and these babies can cost several hundred dollars to replace in Wilmot.Change your vehicle air filter at Walker Automotive when it's dirty.

Your vehicle has a way of letting you know when something's wrong. Consider a vibrating steering wheel. It certainly didn't do that when it was new, so that shake is trying to tell you something. There are a few things that can cause your steering wheel to vibrate as you drive down the road. One of the most common is out-of-balance tires. You may not only feel that wobble in your steering wheel, you might also feel it in the tires. Sometimes it's not there when you're driving at lower speeds through residential areas, and sometimes it starts when you hit highway speeds. So what is tire balance anyway? Well, you have a rubber tire that fits around a metal wheel. It should have the same weight all the way around. If it doesn't, it will start getting the shakes. Ever load your washing machine so that all the clothes are at one side of that drum that spins? When it hits the spin cycle, it can throw that washer against the wall. Th ... 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

Winter is one of the hardest times to keep your vehicle clean. But did you know neglecting to wash your vehicle in winter could cost you a significant amount of money in the long run? Here's why. Many areas deal with snow and ice in the winter, and the salt and sand that are used to keep the road surfaces from being slick are also super corrosive to a vehicle's metal body and undercarriage. That includes all the parts underneath that can be splashed with brine, saltwater and other road debris. Winter is also tough on vehicles where there isn’t snow, sometimes from ocean salt or winter's extra humidity and rain. If you have any breaks in your vehicle's paint, whether it be from a little fender bender or a stone chip, that corrosive winter moisture can get through those cracks and start eating away at the metal underneath. If you can, you should get any dents or damage fixed as soon as possible so your vehicle has a protective layer of paint between road che ... read more

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

You've probably noticed how much easier it is to see when you're driving in the daytime as opposed to at night. It's one of the main reasons about half of all fatal vehicle accidents happen when it's dark. That's why it's important that your vehicle's headlights are in top condition and working the way they should. That means that they're aimed correctly and producing the amount of light they are intended to produce. For many years, headlights were a standardized size and shape. They were what is called a "sealed beam," and when you needed to replace one, it was pretty simple. You just took the old one out and plugged a new one in. But now there are hundreds of different types of lighting systems on vehicles, producing light with such illuminating technology as light-emitting diodes (LEDs), halogen bulbs, high-intensity discharge (HID) bulbs and more. Some vehicles have systems that turn your lights in the direction you turn your steering wheel so you can ... read more

If you've been paying attention, you've noticed that vehicle engines are getting more and more powerful in Wilmot. At the same time, they are getting better and better fuel economy. I've gotta tell 'ya, most of that's because of technological advances in transmissions. To get a better understanding of why that is, let's talk bicycles.You've probably seen plenty of cyclists on Wilmot roads. Perhaps you ride yourself. Then you know that a cyclist's cadence is the number of times per minute he or she pedals. The ideal pedal speed is the zone where they can most efficiently generate power over a sustained period of time. The experienced NH cyclist uses her gears to keep her pedal speed in the ideal zone whether she's climbing a hill, cruising on a flat stretch or killing a downhill.Think of it this way: if you have a 1-speed bike, you really have to pump hard to get up to speed. Your top speed is limited by how fast as you can pedal. And if you're climbing a steep NH hill ... read more
