Wilmot Auto Repair

Myths passed around our Wilmot, NH community start with a grain of evidence and are then built up with a lot of imagination and very elastic logic. And the internet is a breeding ground for automotive myths. Some bloggers recall the vehicles of yesteryear and declare their modern decedents to be virtually maintenance free and that anyone who says otherwise is out to rip you off. To get the truth about auto myths you hear around the Wilmot area, come over to Walker Automotive. Let's examine a couple of the more popular rants and look at the truth behind them.The first one is that the chassis no longer needs lubrication for suspension, steering and the driveline. They declare that anyone who has charged you for lubrication is a charlatan.The truth on which this myth is based is that many new vehicles come from the factory with sealed joints and cannot be greased. However, there are still some grease points on many ca ... read more

Many Wilmot residents don't realize that there is more to exhaust system maintenance than just tailpipes and mufflers, if you can see smoke or if it's too loud. Exhaust service at a full-service automotive center like Walker Automotive is really a lot more comprehensive these days.For example, in the U.S., the federal government required catalytic converters for all cars in 1976 and on-board emission control computers in 1990. NH and federal emissions requirements have forced manufacturers to come up with much more sophisticated ways to comply with environmental laws. This also goes for cars sold in Canada.So, exhaust service has really become exhaust and emissions service. High-tech computer-controlled emissions devices are now necessary. And because it's so sophisticated, we recommend having your emission system checked out by a qualified technician, like the ones we have at Walker Automotive, regularly to make sure everything's working right – which is usually every six month ... read more

Today we're going to talk about on-board diagnostics and the questions we hear from folks around Wilmot, NH, who need answers about diagnostic services. They want to know what diagnostics are, what's involved and what the benefits are. They really want to understand the value of diagnostic scans by a trained technician in Wilmot.These are valid concerns. If you don't understand something it's really hard to know its value. Let's start with some history.Since 1996, all cars and light trucks in Wilmot, NH, have been required to use a standardized diagnostic system to help repair technicians determine what's wrong with your vehicle. The diagnostic system works with the vehicle's Engine Control Module – the computer that controls many engine functions.The computer monitors dozens of components and processes. Depending on what the sensors read, the computer will make adjustments to compensate for conditions and minor problems. When there is a condition that it can't adjust for, the co ... read more

A vehicle's suspension system is tough. It can last for years and after lots of driving for Wilmot drivers. But it can be damaged quickly by hitting a pothole, curb or rock, and it can wear more quickly if you frequently drive off-road or on bumpy roads. A workhorse vehicle — one that hauls heavy loads — is also going to be hard on its suspension system.Because the useful life of your suspension system contains these elements of unpredictability, it is important for Wilmot drivers to have them inspected periodically. Worn, broken and missing parts can be identified during an inspection at Walker Automotive . An ineffective suspension system will decrease the driver's control over a vehicle, so when it is damaged it frequently leads to the worst kind of vehicular damage — dangerous accidents.The suspension system is composed of springs and shock absorbers (or shocks). Springs suspend the weight of the vehicle above its axles. They allow the vehicle to “bounc ... read more

Have you ever noticed that your vehicle has a schedule in your owner's manual for what is called “severe service” maintenance? Let's define what severe driving conditions aren't: The easiest driving a vehicle experiences is traveling on the interstate for 20 miles (32 kilometers) or more at a constant rate of 65 miles per hour (105 kilometers per hour) in 75°F (24°C) weather with only passengers on board. Change any one of those parameters and you are adding stress to your engine. Change them significantly and you are driving under severe conditions.Let's look at the parameters one a time. First, the length of the trip. Short trips around Wilmot are harder on an engine than longer ones. As your engine cools down, water in the air condenses onto the engine. When you heat the engine again, the water evaporates off. This is healthy. But on short trips, the engine doesn't stay hot enough long enough for all of the water to evaporate. So it starts ... read more

There are a number of factors that contribute to the high nighttime accident rate in the Wilmot area, things like drowsy driving and a higher rate of impaired driving. Without a doubt, visibility is a major contributor. Let's focus on visibility…It's said that 90 percent of our driving decisions are based on what we see. Nighttime driving has the effect of reducing 20/20 vision to the equivalent of 20/50 vision. What you could clearly see at 50 feet in daylight can't be seen until you are just 20 feet away at night.Too make sure your headlights are giving you the greatest visibility, visit us at Walker Automotive, located at 3 Deerwood Drive, Wilmot, NH 03287. Please give us a call to make an appointment: 603.526.4848.Accident avoidance is dependent on reaction time. Reaction time deteriorates measurably in low light conditions. One thing we can do to improve visibility is to make sure our headlights are as bright as they can possibly be.He ... read more

Most Wilmot drivers are all talking right now. Better gas mileage. Fewer emissions. NH folks want to save the environment and our pocketbooks.And we Wilmot drivers all know — or should know — that preventive maintenance will help maintain maximum fuel efficiency. But is there something more we can do? After all, some of us Wilmot road warriors can't cut back on our driving, and others would like to do more to economize.Weight is one major enemy of fuel economy. The more you lug around in your vehicle, the more fuel you have to burn to get around Wilmot. And that means buying more gas and producing more emissions.Of course, your vehicle's weight isn't negotiable. And you can't do much about the weight of your passengers. And this isn't an article about diet and exercise.But look around your car. Are you hauling a bunch of unnecessary weight while driving around Wilmot? Do you really need your golf clubs every time you leave your ne ... read more

The exhaust system on a vehicle is more complex than most Wilmot residents realize. It contains everything from old-fashioned pipes and clamps to sophisticated computers and sensors. All NH folks know a properly functioning exhaust system is good for the environment, but sometimes we forget that a damaged exhaust system can be deadly. That's why preventive maintenance on your exhaust system is so important. We can help you with that at Walker Automotive in Wilmot.The exhaust manifold is the first component in your exhaust system. The manifold is attached to the engine. It collects the gases that are produced by the engine and directs them into the exhaust pipes. At this point, these gases are both hot and chemically dangerous.One of the gases produced in your engine is carbon monoxide. This gas is colorless and odorless. Breathing it can cause headaches, dizziness, nausea and drowsiness. Continue breathing it and you will die.To keep this gas and othe ... read more

One might say the most challenging part of being an automotive service technician at Walker Automotive is diagnosing a problem before it can be fixed.Cars are made up of a bunch of complex systems. There usually could be a number of reasons for any given symptom. So, it's challenging to track down the actual cause of the problem. And it can be frustrating for the vehicle owner because it can take time and money to get to the bottom of a problem. If it's not something obvious, it's easy for the customer to focus on the fixing and not the diagnosing.Let us at Walker Automotive introduce you to something we'll call 'Customer Detective Work' –  helping your technician find clues to what's wrong.We start with the detective basics: What, Where and When. Play along with me; You come in to Walker Automotive and your car is making a funny sound... Q: Where's the sound? A: Around the right front wheel. Q: What kind of sound? A: Kind of a clunk, clunk sound. Q: Wh ... read more

Scratching your head? Don't worry, if you don't know what a differential is – you will in a moment. That fact is that if you drive a car anywhere in Wilmot, NH, you have a differential. Whether your vehicle is front-wheel drive, rear-wheel drive or four-wheel drive, you have a differential. Some Wilmot vehicles might even have two or three.Not surprisingly, a differential's job is to compensate for differences; specifically, they're the differences in wheel speed when turning. For instance, imagine taking a corner near your Wilmot, NH, home. Your inside wheel has a shorter distance to travel than the outside wheel as you turn the corner. That means that your outside wheel has to turn faster to keep pace with the inside wheel.The differential allows the wheels to turn at different speeds while still providing power to your vehicle. Without a differential, Wilmot residents' tires would scrub and hop along the pavement during turns like the early cars.Ever noticed the big bulg ... read more
