A Cool and Smooth Transmission in Wilmot

When it comes to preventive maintenance on our vehicles, most of us Wilmot drivers remember to get our oil changed. But services that occur at longer intervals — like transmission service — sometimes get overlooked. Yet transmission service is part of car care. A poorly maintained transmission will fail and lead to repairs.The transmission transfers power from the engine to the drive wheels. When it's clean and well-lubricated, it gives maximum fuel efficiency. But when it gets dirty or worn down, your transmission will suffer. Your transmission relies on transmission fluid to keep everything running well.This is why the transmission fluid must be changed periodically. Your owner's manual will give you a recommended time schedule for this service. Or, you can ask your friendly and knowledgeable Walker Automotive service advisor. Generally, the interval is around 35,000 miles (55,000 km) or every two years. But the interval for your vehicle may be ... read more

Keep Your Cool in Wilmot

Wilmot drivers rely on their vehicle's coolant system to keep their engine cool. Coolant (also called antifreeze) mixed with water flows through your vehicle engine and absorbs heat. The mixture then flows out to the radiator where it's cooled by air flowing over the radiator. From there the coolant/water mix circulates back through the engine to absorb more heat.There's a reason we mix coolant and water. Water alone actually does a good job transferring heat from the engine. The problem is that water boils at a temperature that's easily reached inside your vehicle's engine, so it can turn to steam which does not conduct heat as well and is harder to contain.Also, if it's freezing outside in Wilmot, the water in your engine could freeze while your vehicle is sitting out in the NH cold.So, if you remember your high school chemistry, you'll know that a mixture has both a higher boiling point and a lower freezing point than either c ... read more

Power Steering Service at Walker Automotive in Wilmot

Many Wilmot drivers have been hearing about technological advances in power steering, specifically electric power steering. Some very high-end cars have been featuring electric power steering. Power steering fluid has the necessary hydraulic properties and the ability to lubricate the internal parts. The power steering fluid also protects vehicle components from rust and corrosion.Wilmot car owners should be aware that vehicle manufacturers recommend that the fluid be replaced on schedule. At Walker Automotive, the old fluid is drained and the system cleaned thoroughly. Fresh fluid is then installed.Unfortunately, many Wilmot drivers don't realize how important it is to service their power steering, and some may not even know that it's necessary in the first place. A neglected power steering system can develop leaks that will shorten the life of the pump.Wilmot drivers should be aware of war ... read more

Fuel Injector Cleaning at Walker Automotive

In very simple terms, a fuel injector is a valve that squirts fuel into your vehicle engine. Your engine control computer tells the fuel injector how much fuel to deliver as well as the precise time it should be delivered. Of course this happens thousands of times a minute in every single fuel-injected vehicle driving down Wilmot roads.Most fuel injectors for gas engines are known in the Wilmot automotive community as port fuel injectors because they deliver the fuel to a port just outside the cylinder. The fuel pump provides pressure needed to squirt the right amount of fuel into the engine. A few have recently introduced gas direct injection systems on some engines. They are now available at some NH dealerships. These systems inject the gas directly into the cylinders under very high pressure – many times the pressure of port injection systems. Although more complicated, direct injectio ... read more

Alternative Fuel Vehicles in Wilmot, NH

Let's talk about alternative fuel vehicles. In their quest to reduce the use of fossil fuels and harmful exhaust emissions in our NH environment, automakers will have a number of alternatives for Wilmot drivers very soon.For instance, Flex Fuel vehicles are already available in the Wilmot area. Flex Fuel vehicles can run on gasoline or on E85 fuel. E85 is a mixture of 85 percent ethanol and 15 percent gasoline. The ethanol is made from corn. The benefits to Wilmot drivers are in using less petroleum and reduced pollution. The drawbacks are that E85 gets lower gas mileage and when gas prices are low, E85 can be more than straight gasoline.Wilmot drivers should only use E85 if they have a Flex Fuel compatible engine. Flex Fuel vehicles have special seals and gaskets that can stand up to the high alcohol content of E85. Using E85 in a regular engine can lead to gas leaks and fires.Diesel engines have been around NH  for a long, l ... read more
