Every day you drive, you're sitting behind the dashboard. But how in the world did it get that name? Back in the days of the horse-drawn carriage, horses would kick up dirt and mud on the driver and passengers, "dashing" debris against the carriage. So those who built carriages began installing a board to protect them. So, dash-board. Dashboard. The dashboard is still there, though changed quite a bit from the early days. Now its main purpose is to house the controls and instruments for your vehicle's systems. Of course, you have the speedometer, tachometer and gas gauge. But there are four warning lights you need to pay attention to on your dashboard and instrument panel. Some of these may even be gauges, depending on your model of vehicle. Regardless, paying attention to them is a good idea if you want your vehicle to keep going as long as possible. Oil pressure—The oil pressure light will come on if your engine doesn't have enough pressure in its system. Low oil pressure means ... read more

If you smell gasoline in your vehicle, pay attention to your nose. That's because it has an important message for you. Newer vehicles should never have a gasoline smell inside. One of the most dangerous conditions can come when your fuel line system has a leak or multiple leaks. Vehicles with fuel injectors are under pressure, meaning a crack or small hole in a fuel line can allow vaporized fuel to escape, sometimes around hot engine parts. Gasoline vapor and hot metal? You see the problem. One of the most common causes of a gasoline smell inside a vehicle is a fuel tank leak. The gas tank can rot or be punctured by road debris. A Walker Automotive technician can evaluate the condition of your fuel tank and suggest either repair or replacement. Fuel injectors can develop small leaks around their seals or O-rings. Those can deteriorate over time as the material they are made of gets old and less flexible. A technician can replace those parts. Modern vehicles contain something called a c ... read more

Everybody's got friends like this. You know, the kind who, the minute they get in their vehicle and turn the key, the sound system is deafening. They just love to hear that music, sports, news… anything but the sound of the vehicle itself. And maybe you're that person, too. Here's something to consider: your sound system might be drowning out some valuable clues that could help you diagnose problems with your vehicle, problems that need to be dealt with. So, turn down the volume and listen for these things: A clicking sound when you're braking or turning—You could be missing some parts in your braking system, or it could be damaged. That sound could also signal that components are just plain worn out. Rattling under the hood—If it sounds like metal clanking against metal, you could have something serious going on, maybe an overheating engine or your timing needs adjusting. That knocking sound could also be as simple as you've been using lower octan ... read more

Changes in vehicle design and manufacture have resulted in changed fluid requirements for our vehicles. With the sophistication of engines, transmissions, differentials, etc., it's best for Wilmot residents to always use the proper type of fluid for their vehicle. Using incorrect fluids can actually damage your engine.As engines have become more sophisticated, new weights (or grades) of engine oil have been introduced. Today, there is a much wider range of weights for engine oil as well as a variety of formulations for different types of engines.Transmission fluid, brake fluid and coolant/anti-freeze have changed because the materials that go into making the systems they protect have changed. The fluids in our vehicles generally have two jobs: to lubricate and to prevent corrosion. The fluids formulated for your vehicle are specifically designed to protect the materials that make up its engine parts. Using the wrong fluid may leave some parts vulnerable to corrosion. Further, using th ... read more

Wilmot drivers may feel intimidated when they take their vehicles to a service center. They have questions but aren't sure how to ask. They don't want to feel embarrassed about their lack of knowledge. They don't want to make the service technician feel that they don't trust him.If your service advisor at Walker Automotive uses a term you don't understand, just ask him to explain. Remember, they are the auto service experts. If they came to your place of work, they probably wouldn't understand the jargon, either. When you take your vehicle in to be serviced, make sure you understand the financial issues up front. Ask about payment policies, warranties and, of course, the cost of the work being done.It helps to understand basic services your vehicle needs. Know the difference between a quick check-up and a thorough inspection, which you are getting and which you are asking for. Understand that diagnosing a problem takes time, and time isn't free. If you have concerns about cost, n ... 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

Hello NH! Today's vehicle care topic is: Synthetic Oil vs. Petroleum Based Oil. Synthetic motor oil is a substitute for petroleum based oil. If you aren't currently using it, why not? Synthetic motor oil maximizes engine power and fuel economy. To see why, we'd need a microscope, so we'll have to settle for using our imaginations. The molecules of conventional motor oil are long hydrocarbon chains. Synthetic motor oil, on the other hand, has uniform, round molecules. Which is slipperier, a pile of pencils or a pile of marbles?Synthetic motor oil lubricates better because there's less friction. This results in myriad benefits: better wear protection, cooler operating temperatures, more power and better fuel economy. And synthetic oil doesn't sludge up like conventional oil so it prevents those small oil passages from clogging up. (We see that too often at Walker Automotive in Wilmot.)Some manufacturers are extending oil change ... read more

Let's talk about something critical for all Wilmot drivers: your brakes. Your vehicle is heavy, and it takes a lot of muscle to bring it and your passengers to a safe stop – so everything needs to be in good working order. Here's an explanation on how your disc brakes work: The wheel hub keeps your wheel attached to your vehicle. The brake disc – or rotor – is attached to the hub and rotates with the wheel as you drive around Wilmot. Your brake pads clamp onto the rotor to slow the wheel.The brake caliper straddles the rotor and squeezes the rotor to slow it down. The calipers contain brake pads which press on the rotor when you put your foot on the brake. The brake piston causes the calipers to squeeze and release as you use your vehicle brakes.Your brake pads start to wear the first time you step on the brakes. Eventually the pa ... read more

Whether we're trying to save money, save gas or save the environment, most of us Wilmot drivers have an interest in decreasing fuel consumption. We've all heard about ways to save money on gas in NH, but does it really add up to much? How much can we boost our fuel economy through preventive maintenance and more courteous driving?The US government has a website that actually answers that question. Let's look at some of the data and find out if any of these fuel-saving ideas are really worth the effort. We've all heard that a tune-up can improve gas mileage. It turns out that it can save us 4% at the pump. At $3.50 a gallon, that's 14¢ per gallon in savings, and at $4.00 a gallon, that's a 16¢ per gallon savings.Other common repair items can also save you at the pump. For example, if your oxygen sensor is faulty, it's not delivering the information to your engine's computer that allows it to calculate the right fuel-to-air ratio. The result? The fuel ... read more

Think of how much abuse your brakes take. Day in and day out, they stop your vehicle when it's going fast and when it's going slow. Maybe your vehicle has been vibrating when you brake, or maybe it seems like your stopping distance is a little bit longer than it used to be. Then it's time to get your brakes checked out. After all, you have to be able to stop if you want to be safe. Nearly all newer vehicles have disc brakes on the front, and many have that type of brake on all four wheels. That makes it likely you'll be getting disc brakes fixed at some time in your vehicle's lifetime. Knowing how disc brakes work is as easy as riding a bicycle. If your bike had hand brakes, you'll probably remember a mechanism that squeezed a couple of pads on each side of your bicycle wheel when you applied the brakes. Disc brakes are similar; but instead of the bike wheel, there's a metal disc instead. If that disc is warped or has irregularities in it, it's going to vibrate. It used to be that roto ... read more
