In our auto video today we'll be talking with Alan Peterson about myths surrounding automotive maintenance. You can lump these myths into the statement that "modern vehicles are so reliable, they are virtually maintenance free."Any good myth has some elements of truth. No offense to Wilmot Bigfoot fans, but this maintenance-free myth has more evidence than most. If we look at some isolated areas of auto maintenance, we could conclude that maintenance isn't so important. But other areas would just as easily lead you to believe that maintenance is more important than ever.Here are some examples for our friends in Wilmot. Some vehicles in Wilmot no longer require chassis lubrication. They're made with self-lubricating materials and have sealed joints. There's literally no way to grease those joints. -Chalk one up for the myth.On the other side, some vehicles come with sophisticated variable valve timing. A lot of complicated parts are up in the valv ... read more

All NH pilots have checklists for every aspect of flying. They always use their checklists even if they only have two steps on them. They do this simply because a checklist is a great way to not forget steps. It is also how they can assure a predictable outcome. That is why Wilmot automotive service centers including Walker Automotive have procedural standards for each service they perform. Walker Automotive technicians are trained step by step. And they perform the procedures step by step, the same way each time. By training to procedural standards, NH service centers can assure a quality outcome. The job is done right every time and Wilmot customers leave happy with how their vehicle performs. Each company trains its technicians to standards. The NH automotive industry as a whole is very committed to standards of excellence and encourages individual NH service center operators to apply them to every vehicle they service. An example is how Walker Automot ... read more

Air quality has certainly become a hot issue in our modern world. We install air filters on our ventilation systems and in our vacuum cleaners. There's a filter that cleans the air going into our vehicle's engine — so why not one for the air in the passenger compartment?Foreign and domestic vehicle manufacturers haven't been ignoring the issue. Cabin air filters are becoming a standard feature on newer vehicles. These filters can clean particles out of the air down to three microns, which accounts for pollen, dust and most pollutants. Wilmot residents who suffer from allergies or have a respiratory disorder should be a lot more comfortable. And even if you don't have a medical need for the filter, the cleaner air in your car just might help you breathe better, figuratively as well as literally.Cabin air filters are still fairly new in the Wilmot area, so you'll have to check your vehicle owner's manual to see if you have one. If ... read more

Have you ever had an experience like this in Wilmot, NH? You drive through the one of those automatic car washes. When you get to the end, where the dryer is blowing, your Check Engine light starts flashing!You fear the worst, but within a block or two, the light stops flashing, but stays on. By the next day, the light is off.You wonder; "What was going on?" Well, it's actually a good lesson in how the Check Engine light works.Your air intake system has a sensor that measures how much air is coming through it. When you went under the high-speed dryer, all that air was blasting past the sensor. Your engine computer was saying, there shouldn't be that much air when the engine is just idling. Something's wrong. Whatever's wrong could cause some serious engine damage.Warning, warning! It flashes the Check Engine light to alert you to take immediate action.It stopped flashing because once you were out from under the dryer, the airflow returned to normal. Now the engine ... read more

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

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

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
