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

Hello Wilmot, let's talk about your often-unnoticed but extremely important PCV valve. The energy from exploding fuel is what powers your engine. But some of the vapors from the explosions escape into the lower part of the engine, called the crankcase. The crankcase is where your engine oil hangs out. These gases are about 70% unburned fuel. If the gases were allowed to stay in the crankcase, they would quickly contaminate the oil and turn it to sludge. Wilmot folks know that sludge is one of the biggest enemies of your engine, clogging it up and eventually leading to expensive failures. Also, the pressure buildup would cause seals and gaskets to blow out. Therefore, these gases need to be vented out.Pre-1963, gasoline engines had a hose that let the fumes vent out into the air. In 1963, the federal government required gas engines to have a special one-way valve installed to help reduce dangerous emissions. (Can you ima ... 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 in your engine controls the opening and closing of the intake and exhaust valves. Wilmot drivers need to replace it on a schedule to avoid failure.Timing belts are very difficult to get to, requiring quite a bit of labor to access. Timing belt replacement is one of the more expensive maintenance services, but the cost at Walker Automotive to correct an engine damaged by a broken timing belt is much, much more.The timing belt has a tensioner to help maintain proper belt tension. The tensioner should be replaced along with the timing belt and any idler pulleys at the vehicle manufacturer’s specified service interval. Your Walker Automotive service advisor can help you with the timing belt.Give us a call.Walker Automotive3 Deerwood DriveWilmot, NH 0328760

Most Wilmot drivers know something about preventive maintenance on a vehicle. We know we should routinely replace the oil and wiper blades and other fluids. But have you heard of a PCV valve ? This little car part needs to be replaced regularly or it can cause some serious problems in your vehicle engine.PCV stands for Positive Crankcase Ventilation. The crankcase holds your motor oil and is located at the bottom of your engine.When fuel is burned in your engine, it produces waste gases that are mostly vented out through your exhaust system. But some of these gases push their way past the pistons and into the crankcase. There, these gases can mix with motor oil to produce oil sludge, which can damage vehicle engine parts through corrosion and by clogging engine passages. Wilmot vehicle owners should be advised that if the engine is running at high speeds, these gases can also cause pressure inside the crankcase to build up. This pressure, in turn, can ... read more

Most auto manufacturers recommend an interval for an air conditioning system inspection. The inspection uncovers leaks, worn hoses and assesses the condition of the other components.Environmental laws in some around Wilmot require leaks to be repaired before refrigerant can be added. Also some parts manufacturers require other components to be replaced along with certain failed parts in order to maintain the new part warranty. This is because a given failure may be the result of another worn or damaged part that will, if not replaced, prematurely damage the new component.Walker Automotive in Wilmot is fully equipped to restore your flow of cool air.Walker Automotive3 Deerwood DriveWilmot, NH 03287603.526.4848

The price of gas in NH has got people in Wilmot talking. It seems that Wilmot folks who need a bigger vehicle to carry family and gear, or provide four wheel drive, are hit especially hard. That is why we thought it would be good to review some things that anyone can do to improve fuel economy. First let's start with how we drive around NH. People in Wilmot may not realize that they can really save on gas by just changing a few driving habits. One of the biggest is jackrabbit starts - you know, flooring the gas as soon as the light turns green. That really wastes a lot of fuel. Building up your speed at a slower pace uses less fuel and is easier on your engine and drive train. And don't drive with one foot on the brake. That's also a drag on fuel economy, and it wears out your brakes faster, too. Another thing Wilmot drivers can do is drive more slowly - but only when it's safe. Sometimes on the freeway we drive an extra five ... ten ... read more
