A fuel injector is a valve that delivers fuel to a vehicle's engine. It has to deliver the precise amount of fuel to precisely the right place, precisely when the engine needs it. The fuel also has to be mixed with air before it can burn in the engine.Fuel injectors are engineered to spray fuel in a specific pattern into the engine. (The pattern varies by engine type and design.) In order to achieve these spray patterns, the fuel must be pressurized.The pressure in a fuel injection system varies depending on its type. Many gasoline engines use port injection systems, which operate with a pressure of 60 pounds per square inch. Newer direct injection systems operate at 10 to 30 times that pressure. Some diesel passenger vehicles have fuel injectors that operate at 30,000 pounds or more per square inch.Vehicles have one fuel injector for each cylinder in the engine. Your vehicle's control computer constantly monitors the engine and various sensors in the vehicle.  It ... read more

So what is the most distracting food to have in the car while driving around Wilmot?Is it: A Hamburger; Coffee; A Soft Drink, or Gummy Bears? Well, you may be surprised to learn that all but the gummy bears are in the top ten most distracting foods when you are driving.

Here's an interesting statistic for our in Wilmot, NH, drivers: Only 30 percent of car batteries make it to 48 months. And the life expectancy varies by where you live. It ranges from 51 months in extremely cold areas to just 30 months in extremely hot climates.Why is that? It turns out that it's our modern cars with all their electric accessories that are to blame. Things like, GPS, DVDs and entertainment computers are keeping vehicle batteries from maintaining a full charge. The longer a battery goes with a low charge, the sooner it'll die.It's clear that you Wilmot drivers need to recharge your batteries. This is the job of the alternator. The problem comes when the car's demand for electricity is high and we are driving in stop and go conditions or short trips around Wilmot. The alternator just can't keep up.The result is shortened battery life. So what can we do to improve our battery's health?We need to keep the battery as close to a full charge as possible ... read more

  One topic that hits the news in NH on a regular basis is the price of gas. The answer for some NH drivers is to buy a vehicle that gets better fuel economy. For those of us in Wilmot who don't want to add a car payment to our monthly expenses, we need to improve our fuel economy any way we can.Following recommended service intervals by coming into Walker Automotive is one of the best ways people in Wilmot can keep their vehicle running efficiently. That means better fuel economy. When you give it some thought, it only makes sense. Dirty oil or transmission fluid can't lubricate or clean. That means more drag which reduces fuel economy.Keeping up with scheduled oil changes and transmission services will save gas for NH drivers.Dirty engine air filters are another efficiency pirate. They rob your engine of enough air to effectively burn the fuel, so you need more gas to get the job done. Replacing a dirty air filter can pay for itself in fuel savings before the next oil change.You ... read more

All Wilmot service advisors know that without the alternator, the battery will go dead in a few miles. The serpentine belt may also run the pumps for both the power steering and power brakes. And on many vehicles, the serpentine belt powers the water pump. The water pump circulates coolant through the engine to keep it within normal operating temperatures. (On some vehicles, the water pump is powered by the timing belt instead of the serpentine belt.) So you can see the serpentine belt does a lot of work. And it if breaks, it affects a lot of systems. That's why your vehicle manufacturer and your service advisor at Walker Automotive have recommended that it be changed every so often so that it doesn't fail.Your friendly and knowledgeable Walker Automotive service advisor can perform a visual inspection of the belt to see if it has any cracks that signal the belt could fail soon and will measure the am ... read more

The cooling system keeps NH vehicle's engines from overheating while they are driving around Wilmot. Its job is to move heat away from the engine. Let's talk about the various components of the system and how they make this happen.The radiator is the part most Wilmot drivers associate with the cooling system. Coolant flows through the radiator which has fine cooling fins that draw the heat out of the coolant and dissipate it into the air. To make sure there's enough airflow over the radiator, a fan pulls air over the cooling fins even when the vehicle is idling.In some vehicles, the fan is powered by the serpentine belt. On others, an electric motor runs the fan. Electric fans turn on and off as needed. You may have heard the fan kick on shortly after you turn your vehicle off. The sensor has determined that the engine needs a little help cooling down to a safe temperature.A hose connects the radiator to the water pump. The water pump ... read more

Buying a new car in Wilmot is always a big financial decision. The allure of that new car smell is powerful, to be sure. But what if your current car is still in good shape? How do you decide?People in Wilmot who've been used to driving a new car every three to five years may be having second thoughts in this economy. For many, the question is, how does the certainty of a new car payment stack up against uncertain repairs for a car that may be out of warranty?For purposes of our discussion, let's assume you live right here in Wilmot and have a five year old vehicle. It's now paid off. If you keep it, you fear that there'll be some repairs over the next five years, but you really don't know what to expect. For help we turned to maintenance and repair information for cars and trucks. With this data, they project likely service and repair costs for a particular make and model. They're able to use manufacturer's maintenance sch ... read more

Virtually all vehicles come with power steering, so many Wilmot drivers have never driven a car or truck without it. Power steering assists you when you turn your vehicle steering wheel. Without it, it would be very hard to steer. Now this power assist comes in a couple of forms. In recent years, a lot of vehicles have an electric motor that reduces steering effort and helps improve performance and handling. The other kind of power steering is hydraulic. This is the kind most older NH vehicles — and a lot of newer ones — have. Power steering fluid is pressurized by a pump and is used to assist steering. Of course, vehicles need the right amount of fluid in the system. If it's too low, your steering is affected and you could damage your vehicle pump. Also, power steering fluid can become corrosive over time and damage the pump, hoses and connectors, leading to leaks and repairs. Power steering se ... read more

We find that a lot of Wilmot drivers are a little tentative when they talk with their automotive advisors. They want to ask questions but don't want to be embarrassed or seem pushy. Vehicles are very complicated and there's more to know about them than most of us have the time to learn. Maybe it's because vehicles have become so much more reliable that the average person just doesn't need to know as much to keep their vehicle on the road.You know, your local hospital has a Patient's Bill of Rights that they post throughout the hospital. We think our Wilmot automotive service customers also have a right to ask any question they need to understand what is wrong with their car and what it will take to fix it. They need to feel free to ask the cost and benefits of recommended services. And they certainly have a right to understand the financial end of the transaction.It's all about the communication. It's a little harder when you're trying to find the right ... read more

Wilmot residents know that engines need to burn fuel to operate. Fuel is pumped from your fuel tank to your vehicle 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—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 vehicle engine.Direct injection engines burn fuel more efficiently than conventional vehicle 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 gas mileage. The turbocharged version delivers 350 horsepower.Why ... read more
