Even in the months where temperatures are cooler, heat is still an enemy of your vehicle. When your engine runs, it creates heat, so there are numerous heat shields that protect other parts from those higher temperatures. Heat shields are installed around several areas of the exhaust system. Others prevent heat from reaching parts of the vehicle. Still others prevent heat from reaching the ground (or maybe grass underneath) and starting a fire. If you remember your space travel history, you'll know how important a heat shield can be. John Glenn was the first American to orbit the earth, but during that maiden orbital flight, a sensor on board was indicating the heat shield on his capsule, Friendship 7, was loose. If it had come off, his spacecraft could have burned up upon re-entry. Fortunately, the heat shield stayed on, and Glenn made history. Unfortunately, the heat shields on your vehicle don't have warning systems like the space vehicles did.&nb ... read more

You may live in a region where roads become pockmarked with craters known better as potholes. They're caused by moisture seeping through a compromised road surface that can freeze, expand and literally punch holes in the road. And when your vehicle hits one of those holes that's big enough, the impact can flatten a tire, bend a wheel or tear apart a suspension component. To minimize pothole damage, leave enough room between you and the vehicle in front of you so you can see the road surface and any upcoming potholes. That way you'll have time to slow down and steer around them. Also, if you see what looks like a puddle of water, it may be hiding a pothole underneath, so treat it as if was a pothole. If you keep your tires inflated to the manufacturer's specifications, they're more likely to withstand hard impacts. And the slower you're going when you hit a pothole, the less likely you are to break something. But if you do find you've hit ... read more

Today's Walker Automotive article focuses on severe service maintenance. Many Wilmot drivers are not aware of them and yet there are also very vocal advocates in NH who think that severe service schedules apply to everyone. Somewhere between a complete lack of awareness and the dire blanket statements lies a reasonable approach to severe service maintenance at Walker Automotive.To back up a little, vehicle owner's manuals have schedules for preventive maintenance: things like oil changes, transmission service and so on. They say you should change your oil after a certain distanced traveled or after so many months. Wilmot drivers understand this very well. What they may not know is that there are actually two service schedules: the regular schedule and the severe service schedule. The mileage and time intervals are lower on the severe service schedule.Now when you hear 'severe service,' you may think it doesn't apply to you because you don't feel ... read more

Mirror, mirror on the door, why is my vision there so poor? Well, you could have a broken outside rearview mirror that's disabled your blind spot vision there and endangering your ability to see some of the traffic around you. Outside rearview (or door) mirrors are important safety devices that are thoughtfully designed to help drivers see. And there are a variety of ways those door mirrors can develop problems. One is when the glass is broken in them. Sometimes it's caused by an accident or vandalism. But without your ability to see in that mirror, you could be driving blind, unable to see drivers approaching from the rear in adjacent lanes. Sometimes it's as simple as having the glass replaced. You'll greatly enhance your safety if you do. Then there's the door mirror that you can't adjust. First, let's look at a common scenario in later models, the power mirror. They're great when they're working, awful when they're not. Sometime ... read more

If you've ever noticed your vehicle's lights are dim or not working at all, the problem could be many things. But one possibility is your battery cables aren't doing their job. A power outage in your vehicle is similar to one in your house and needs to be repaired to get things back to normal. Battery cables connect your vehicle's battery to the vehicle itself. There is a positive cable when provides the power and a negative cable that connects to the vehicle chassis and provides a ground for electrical components. A failing battery cable may cause your vehicle not to start. Your starter may turn over very slowly. Or you may just hear a series of clicks. One other clue is on your dash—the battery warning light. There are many things that can cause power issues in a vehicle, but it's important to keep battery cables clean and maintained. Salt and corrosion are enemies to any power system. A technician can keep things in t ... read more

We all have joints in our own skeletal system, but did you know your vehicle has some joints of its own? One of the most important is called a ball joint. One of the interesting things is that it's somewhat similar to the ball and socket joints we have in our hips and shoulders. A ball joint allows two parts it joins together to move in more than one direction at the same time. Think about your wheels. They have to move up and down when there are bumps in the road but in sideways directions when you are making a turn. As you can see, the ball joints are important for your steering and handling to work correctly. Since ball joints do so much, they can wear out and become loose. When the ball wears down or the socket gets worn, there can be too much play in them. It can get so bad that the ball can come out of the socket and your wheel can fall off, a dangerous situation. Ball joints can also seize up. Some of them are sealed and never require maintena ... read more

You expect your heater/air conditioner to work like it should. You have a control for temperature and one for fan speed. You even have a control for what vents the air comes out of. Don't be surprised one day if your blower fan develops a mind of its own and starts going crazy. Most of the time, you may find that it starts blowing at full speed, and nothing you do to try to control it does any good. This is what may be happening. Your blower motor has an electronic component called a resistor. It does what its name says; it offers resistance. When you want the fan to run more slowly, you turn the fan speed down. That resistor accomplishes that by turning its resistance up. When the resistor fails, the power has nothing to slow it and the fan speeds up. It's a small part and can fail due to age or corrosion. It's usually not an expensive part, either, but it's often found in a location that's not that easy for the technic ... read more

The other day, a driver was trying to open his vehicle's hood so he could add some windshield washer fluid. But when he pulled the hood release inside the car, nothing happened. Usually, opening any hood is a 2-step process. You pull the hood release (which is usually a handle under the dashboard to the left of the steering column) and listen for the hood to pop up slightly. (It doesn't open all the way because it has a safety latch to prevent you from accidentally opening it up while you're driving.) Then, you get out and find the latch, usually through the grille near the hood. There's a little handle on it which you push, slide or pull (there are a few different types) at which point the hood can be opened up all the way. But in this driver's case, the hood would not release at all when he pulled the handle inside. Not knowing what to do, he called his service advisor, who told him to bring it over. The reason? A hood with a broken latch cou ... read more
