Wilmot Auto Repair

Today we want to talk to Wilmot drivers about timing belts. They're something that many drivers don't know much about and yet your vehicle won't run if it's broken – and it could cause many thousands of dollars damage if it does break. A broken timing belt is usually a tale of woe. Even though timing belt replacement is scheduled in the owner's manual, it's not the kind of thing that most Wilmot area auto owners remember because it's not well understood.Let's review what a timing belt does. As most know, the engine's power is generated in the cylinders. A piston rides up and down in the cylinder. During the first down stroke, an intake valve at the top of the cylinder opens and air and fuel is drawn into the cylinder. Then the piston returns to the top, compressing the fuel and air mix. At the top, the spark plug fires, igniting the fuel, pushing the piston down in the power stroke. As the piston once again returns up in the final stroke of the cycle, an exhaust valve opens at t ... read more

If you are a driver in Wilmot and you aren't currently using synthetic motor oil in your vehicle, maybe now's the time to consider it. Need more information? Well, synthetic motor oil is a substitute for petroleum based oil. Synthetic oil doesn't gel or gum-up like petroleum based oil and it doesn't vaporize as easily. It protects better in severe driving conditions like stop and go driving around Wilmot, as well as in very hot or very cold conditions. More and more new vehicles are being delivered with full synthetic motor oil, with the recommendation to use synthetic for the life of the vehicle. Why is this? 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 more slippery, a pile of pencils or a p ... read more

Today in the Walker Automotive auto care blog, we're going to talk to Wilmot drivers about oil change intervals. It seems that as engine technology advances, oil change intervals become longer for Walker Automotive customers. For example, recently four of the world's largest vehicle manufacturer's shortened the published intervals for several of their engine models. They originally published intervals that extended out to a much as 8,000 miles (13,000 kilometers).In real world Wilmot driving, the oil started to sludge up before the recommended change interval. Oil sludge is a thick jelly-like substance: quite literally petroleum jelly – like Vaseline. This goop was clogging vehicle small engine passages so the oil wouldn't flow to some parts of the engine. This resulted in engine damage. We see it too often at Walker Automotive in Wilmot.The vehicle manufacturers began to offer an extended warranty to cover sludge damage. But there was a catch: the vehicle owner ... read more

The government mandates a lot of equipment on cars in Wilmot, NH: emission devices and control computers, safety equipment like airbags and crash worthiness requirements.

The average vehicle is now over nine years old. Two thirds of vehicles on the road in NH have more than 75,000 miles (120,000 km) on them.

We live in such a disposable society. It's amazing all the stuff we throw away. New stuff comes out so fast, we just toss the old and move on. In the old days, NH folks were real sticklers about taking care of their things. If something got lost or ruined by neglect, tough - they had to do without. Most Wilmot drivers couldn't afford new vehicles very often, so they had to make them last as long as they could.It's a good thing that vehicles are more reliable these days. They just don't break down as often. And the good news for us NH penny pinchers is that a modern vehicle can easily go 200,000 miles/320,000 km with proper care.

  Hello Wilmot, let's talk about brakes. But the mechanical aspects of the brakes themselves are just one issue. There's also the power brake pump and brake fluid. And then there are the tires, which are critical to the effectiveness of the brakes.Let's step back. A new vehicle or truck rolls off a local Wilmot showroom floor. It has brand new brakes with brand new brake pads. The brake lines and pump are filled with fresh fluid and are completely clean inside. And the tires are brand new, with full tread. It is ready to go.Naturally, braking power is at its peak performance. Now the miles/kilometers start to add up on the vehicle. Wilmot drivers tend to focus on the brake pads. In the automotive business, the pads and shoes on drum brakes are called the friction material. That's because they provide the friction used to stop the vehicle. The pads are designed to be effective throughout their useful life – it's not until they are worn so thin as to be out of 'specs'  t ... read more

All modern Wilmot vehicles come with fuel injection systems, so it's a topic Wilmot drivers need to know something about. The mighty fuel injector is a valve that delivers the gas or diesel fuel to the right place, in the right amount at the right time—to be mixed with air and burned in the engine.So how many fuel injectors does your vehicle have? There's one for each cylinder. So four, six or eight for most folks in Wilmot, NH. Some vehicles have 10 or 12 cylinders. The engine control computer makes adjustments to the fuel injector as it monitors the engine and other sensors. Fuel injectors are a pretty high-tech.Walker Automotive can help Wilmot drivers with a fuel injector cleaning service. What's the benefit? In order to work right, the fuel injectors have to deliver the fuel at a precise pressure at a very precise time. It's important that the fuel is sprayed in a particular pattern as determined by the engine design.Over time, varnish can start to buil ... read more
