Wilmot Auto Repair

Today's Walker Automotive post focuses on using coolant. If you pour in the wrong kind, it won't protect the cooling system and may even void the warranty. Check your vehicle owner's manual. Of course, your Walker Automotive service advisor will know the proper coolant for your vehicle.Brake fluid is confusing for some Wilmot drivers. Back when we opened Walker Automotive, most vehicles used Dot 3 brake fluid. Now we have Dot 4 and Dot 5. Some Wilmot residents mistakenly think the higher numbers are an upgrade. You know, if 3 is good then 4 must be better. That's not how it works. They are different formulations to meet the demands of differences in brake systems. Only one of them is designed for your vehicle.Ditto for transmission fluid. For decades there were two basic types of tranny fluid used at Walker Automotive: friction modified or not. With the tremendous engineering advances in vehicle automatic transmissions, there have been several new types of fluids developed to pr ... read more

The serpentine belt is aptly named since it snakes around under your hood. It may lack its namesake's fangs, but it sure packs a wallop when it breaks.The serpentine belt powers a lot of engine systems. It runs the alternator, which charges the battery; the water pump (on some vehicles), which cools the engine; the air conditioning, which cools the driver and passengers; and the power steering pump, which allows for easier steering. When the belt breaks, all of these systems shut down.Okay, so maybe you can live without air conditioning and power steering for a while, but your battery can't live very long without an alternator, and when the cooling system goes down, your vehicle engine will overheat. That's why Wilmot drivers should never wait to get a serpentine belt replaced.Serpentine belts are fairly inexpensive at Walker Automotive in Wilmot. And they look downright cheap when you compare them to the cost of an overheated vehicle engine, a tow truck, time lost on the road, inconve ... read more

  Most Wilmot drivers don't even think about their air conditioner. Now here's a tip for Wilmot vehicle owners: Run your air conditioner every so often during NH winters. This circulates the lubricant to help keep the seals from drying out. The air conditioner actually removes some of the moisture in the air. So if you have trouble with fogging on your vehicle windshield during NH winters or during a rain storm, running the A/C on the defrost setting should help. Now on some Wilmot cars you can't run the A/C at the same time as the defroster. Don't ask me why, but I suspect lawyers were involved.Also, air and water can get into the A/C system. That can reduce the efficiency of the system and also lead to corrosion that causes damage. Wilmot drivers should periodically purge the system and replace the refrigerant to remove the air and water.NH drivers would be wise to learn the ea ... read more

Your cooling system is very important. It circulates coolant through the radiator and your engine to protect your vehicle from overheating. There are five main components to the cooling system: the radiator the radiator cap the hoses the thermostat the water pump The water pump's like the heart of your cooling system, circulating the fluid throughout your vehicle. It's a small pump that's driven by the engine; usually by belt, but sometimes by a chain or gear.The water pump only operates when the engine's running. Water pump failure is pretty routine. We see it often at Walker Automotive. Some start failing at around 40,000 miles/64,000 km, but most fail by 100,000 miles/160,000 km. Consult your owner's manual or friendly and knowledgeable service advisor at Walker Automotive to see what's recommended.Since a water pump either works or it doesn't, you need to change it when it fails. Water pumps fail in one of two ways: the bearings fail or they ... read more

Your vehicle's exhaust system is more than just a tailpipe and a muffler. In fact, it is one of the most complex systems on your vehicle. The manifold is attached to the vehicle engine. It collects exhaust from the cylinders and directs it into the exhaust pipe. Gaskets seal the connection of the manifold to the engine and to other joints. A cracked or loose manifold or a leaking or damaged gasket can allow dangerous gases to enter the passenger compartment of a vehicle. One of these gases is carbon monoxide, which is colorless, odorless and deadly. For this reason, it is important Andover residents keep their exhaust system in good repair. The pipes that connect the various parts of the exhaust system can rust or be damaged by rocks or other road debris. Such damage can cause dangerous gases to leak into the air.The catalytic converter is the next component of your vehicle exhaust system. It sort of looks like a m ... read more

Wilmot consumers are demanding. We want a safe, reliable vehicle that handles well and is comfortable to ride in. Oh, and we want good fuel economy, too. We also want vehicle repairs that are cheap, fast and easy. Unfortunately, one usually comes at the cost of the other.Today's vehicles have made significant improvements in reliability and performance over the last few decades. They also deliver more power to Wilmot drivers more efficiently than ever before. For example, some of today's 4-cylinder engines are equal to yesterday's V-8's. Our vehicles also offer an amazing range of features that make them more comfortable and convenient than ever before.But all of that improvement has come at a price for Wilmot vehicle owners. Our vehicles are more complicated and difficult to repair than ever before. They have numerous mechanical and electrical systems. Fuel systems are so complex they have to be run by a computer. Our vehicles are covered with sensors and high-tech electronic equ ... read more

When it comes to your vehicle, it all starts with the battery. Proper battery maintenance is important for two reasons:First, your vehicle won't start or run without it. Second, it is the key to the long life of your auto electrical system. If your battery isn't working efficiently, your alternator has to work overtime to make up for it, and other electrical components can suffer as well.A number of years ago sealed batteries were introduced to the local Wilmot, NH, market. They were hailed as being 'maintenance-free batteries.' While it is true that you can't get in and adjust the electrolyte levels of a sealed battery, it is by no means maintenance free.Batteries are very sensitive to changes in the weather around NH. Temperature really affects auto battery performance. A battery inspection is an important part of your spring and fall checkups. Next time you're under your hood, take a look at your battery. Is it clean and free of residue? A dirty battery will drain. Is there corros ... read more

Wilmot drivers want their tires to last as long as possible. Two ways to extend tire life are wheel balancing and tire rotation.When wheels are out of balance, they wobble and vibrate. That makes the tires wear in a cupping pattern. If a front wheel is out of balance you'll feel it in the steering wheel. If it's a rear wheel you'll feel it through your seat. To fix this, your technician at Walker Automotive puts weights on your wheels to balance them out.That brings us to tire rotation. The front tires on a vehicle wear out faster than the rear tires. As they push through turns, the shoulders of the front tires wear down. So rotating front and rear tires allows them to all wear at about the same rate over the life of the tire.Proper tire inflation will also help Wilmot folks' tires last longer. Underinflated tires wear more on the shoulder and may even overheat. This could cause tire damage or a blow out. Overinflated tires wear too fast in the middle.Four-wheel-drive ... read more

The timing belt rotates the cam shafts which open and close the valves that allow air, fuel, and exhaust to flow through the engine as it powers your car when you drive around Wilmot.An old timing belt can lose a “tooth” in the belt allowing it to slip. The engine could stop or misfire. Timing belt slips – or a broken timing belt – can be disastrous on some engines. In “interference” engines, open valves can get in the way of the piston when the timing belt breaks or slips. When that happens one or more valves can be bent requiring expensive engine repairs.It is important for Wilmot drivers to replace their timing belts as recommended in their owner’s manual to avoid unnecessary breakdowns. Ask the team of professionals at Walker Automotive in Wilmot if it’s time for your timing belt to be replaced. Walker Automotive3 Deerwood DriveWilmot, NH 0328760

Don't you hate it when you hear that squeal from under the hood when you're zipping down a busy Wilmot road? It usually means there is a problem with the serpentine belt. The serpentine belt powers a lot of engine accessories. It runs the alternator - which charges the battery; the water pump - which cools the engine; the air conditioning and the power steering pump. All are pretty important parts. It is called a serpentine belt because it snakes around a bunch of engine components. Serpentine belts are amazingly tough. They can last for years and go long distances. Like all moving parts, however, they eventually wear out. If your belt breaks while you are driving around Wilmot, everything will come to a halt within minutes. You need to stop the vehicle immediately or it will overheat, potentially causing engine damage. You can be sure that it won't happen at a convenient time or place. (As if there was a convenient time or place!) You might even need to get your vehic ... read more
