Wilmot Auto Repair

Wilmot residents know that engines burn fuel to operate. Fuel is pumped from your fuel tank to your engine where it is squirted—or injected—into your engine's cylinders. This is the function of the fuel injectors.There are two ways to inject fuel into an engine. Fuel needs air to burn, so in the first method, fuel is injected into a port and allowed to mix with air—and before it is drawn into the cylinders. In the second method, fuel is injected directly into the cylinders and mixes with air after it enters the engine.Direct injection engines burn fuel more efficiently than conventional engines. Some models can deliver the power of a V8 with the economy of a V6.For example, in one family of engines, the conventional version (a V6) delivers about 250 horsepower. The direct injection version delivers over 300 horsepower and gets about the same . The turbocharged version delivers 350 horsepower.Why the big difference in power? Direct inj ... read more

When you get an oil change, it's always a safe bet to just use the type of oil the manufacturer recommends. But sometimes we're asked if we'd like conventional or synthetic motor oil. We glance at the price tags on the two options and choose the cheaper one. But in this case, the more expensive oil might be the better bargain for Wilmot drivers. Conventional oil is made from petroleum. Its molecules form long hydrocarbon chains. Synthetic motor oil is either more highly refined petroleum or completely man-made. Its molecules are more uniform. This provides advantages over conventional motor oil. First of all, the molecular structure of synthetic motor oil makes it more slippery than conventional oil so it lubricates better. This translates to better wear protection for Wilmot drivers, cooler operating temperatures and more engine power. Further, synthetic oil is more heat-resistant than conventional oil, and it doesn't vaporize as ea ... read more

The function of the fuel filter is pretty self-explanatory. It filters your fuel. The fuel filter is in the fuel line somewhere in between the fuel tank and the engine. Both gas and diesel vehicles around Wilmot use fuel filters. For more information about your fuel filter, visit Walker Automotive at 3 Deerwood Drive in Wilmot, NH 03287.Please call 603.526.4848 to make an appointment. Generally speaking there's not a lot of dirt in our Wilmot area auto fuel supply, but there is enough that you want to screen it out. The problem actually gets worse the older your vehicle becomes. That's because dirt, rust and other contaminants will settle out of the fuel and onto the bottom of the fuel tank. After your vehicle is five years or older, it can actually have a fair amount of sediment built up.That just means that the fuel filter has to work harder as your vehicle ages. It'll get clogged sooner and need to be replaced more often.A symp ... read more

Nowadays, Wilmot drivers are paying more at NH gas pumps. For some families it adds up to several hundred dollars every month. That's got to come out of the budget somewhere. This is one of the reasons many NH drivers are putting off buying a new car. They plan on keeping their old vehicle for a year or two longer than before.Even now, 2/3 of the personal vehicles on our local Wilmot, NH, roads have over 75,000 miles (120,000 kilometers) on them. The average age of vehicles is over nine years. And most people in the Wilmot area can't afford to be stranded or inconvenienced by a breakdown. So following a regular maintenance schedule, like personal diet and exercise plans, is actually critical to preserving your investment.Determining what to do for a higher-mileage vehicle can be challenging because many owner's manuals don't publish service intervals after 60,000 miles (100,000 kilometers). Thus, Wilmot drivers need to be better at keeping records and planning for preventive maint ... read more

When I was a kid, my dad always made sure he took the cars in for Spring and Fall checkups. I was telling a friend that it's about time to get into Walker Automotive for a checkup and he said that he read on the internet that modern cars don't need seasonal service.My friend is (technically) right about some things, but from a practical standpoint, a seasonal check up still makes sense.Back when my dad was teaching me about how to take care of the family vehicle, most of them used a different weight of oil in the winter and in the summer. But most of today's modern engines run the same oil year round. High-tech engines and high-tech motor oils are better able to handle the seasonal changes.Your owner's manual or Wilmot service advisor at Walker Automotive can tell you the right oil to use.Of course, you're concerned about the coolant or antifreeze. You don't want to overheat in the NH summer or freeze up in the wi ... read more

Underinflated tires waste gas for lots of folks in the Wilmot area. Think how hard it is to walk in sand – you just have to work harder because of the resistance. When your tires don't have enough air in them, their rolling resistance is dramatically increased and it simply takes more gas to get from here to there.Always check your tire pressure when you gas up at one of our local Wilmot service stations. If they're low – even just a little bit – bring them up to proper pressure. There's a sticker on the inside of your driver's door that gives the manufacturer's recommended tire pressure.And don't rely on your tire pressure monitoring system to alert you to when you need more air. The TPMS system is set to warn you when pressure drops 20 percent below recommendations. That's severely underinflated and you needed more air a long time ago. And if you have a slow leak – get it fixed right away at Walker Automotive.Get som ... read more

For those of you in Wilmot, NH who pay attention to these things, you may have been hearing about the new direct injection engines and want to learn more about them. Some deliver the power of a V8 with the economy of a V6.For example, in one family of engines the conventional V6 makes about 250 horsepower. The direct injection version of the same engine makes over 300 horsepower and gets essentially the same fuel economy. The turbocharged version makes over 350 horsepower.So what are the differences from a conventional engine?The core difference is in the fuel injection system. The system most vehicles use now is called a port injection system. The fuel injector squirts fuel into a port just outside the cylinder where it's then drawn into the engine with the air.With a direct injection system, the injector squirts the fuel directly into the cylinder. The gain in power and economy come because fuel injected directly into the cylinder dur ... read more

The drive train in your vehicle includes all the components that transfer power from the transmission to the wheels. Those components differ depending on what type of vehicle you drive, namely, front-wheel drive, rear-wheel drive, all-wheel drive or four-wheel drive. The preventive maintenance your driveshaft needs will also differ by what type of vehicle you drive.Let's start with front-wheel drive. In this vehicle, the transmission and the differential are combined in one component, known as the transaxle. The transaxle is connected to two half-shafts (axles), which are then connected to the wheels with a constant velocity (or CV) joint, which is protected by an airtight rubber boot.Walker Automotive service for this type of driveline includes servicing the transaxle and inspecting the CV boot. If the boot is damaged, the CV joint will need to be inspected, and the boot will need to be replaced. If you hear a clicking noise ... read more

Imagine you've left Wilmot and you're up in the arctic on a dog sled.Your dog team is pulling straight and true. You can cover a lot of ground quickly. Now imagine what would happen if one or two of the dogs wanted to go their own way and were pulling off to the side.That would slow you down. You would have to work harder to keep the sled going where you want it. The dogs are all working as hard as before, but you're covering less ground for the same effort.You're wasting kibble.The same is true of your vehicle when the wheels are out of alignment. That wheel that's pulling to the side is dragging down the rest of the vehicle; so you push a little harder on the gas pedal to keep up your speed. You're wasting gas.So have your wheel alignment checked at least once a year. It is important to get it checked right away if you feel the vehicle pulling to one side.Sometimes we Wilmot residents bump a curb or hit a pothole and knock our wheels out of alignment. An accident can take the wh ... read more
