Prepare Your Windshield for Winter (Wiper Blades and Fluid for Freezing Temperatures)

Winter and freezing temperatures present challenges for different parts of your vehicles.  For example, winter tires give you better traction on snow.  But some parts of your vehicle that may need special attention for winter are your windshield wipers. You may have found yourself in the middle of a snowstorm when your windshield wipers are doing nothing but streaking slush that ices up on contact on the glass.  Now you're more blind than you were before! Obviously being able to see during a snowy or icy winter event is important for the safe operation of any vehicle.  So keeping your windshield and rear window clean can go a long way to guarantee you can see your surroundings. Let's start with the wipers.  Blades that are good for hot weather may not be robust enough for freezing weather. You can buy special winter wiper blades that stay flexible during sub-zero temperatures.  The stiffer frames that hold them have a rubber covering that prevents ice and ... read more

Losing Your Spark (Spark Plug Replacement)

When's the last time you thought about spark plugs? You probably don't remember.  That's because spark plugs usually last a long time and don't need much attention.  But they don't last forever, and when they start going bad, they'll send you a few clues. Vehicle is hard to start.  Fuel economy is going down Acceleration isn't what it used to be Engine runs roughly Check Engine light is on There are many things that can cause those symptoms, so it's wise to head on over to your vehicle repair facility to have them look over your vehicle.  But the problem could be your spark plugs. They do wear out, not producing a strong enough spark to ignite your fuel the way they're designed to.  A closely related problem is failing spark plug wires, and a technician will test for both possibilities… and more.  Your vehicle's manufacturer recommends changing wires and/or plugs at certain intervals.  Spark plugs are made out of different materials and some ... read more

Objects in the Mirror (Rearview Mirror Safety and Maintenance)

You may remember a song that went, "Objects in the rearview mirror may appear closer than they are." While that was a song about life's lessons, there are a few things we should all know about how important rearview mirrors are to safe driving. While new electronic devices are helping drivers be aware of surrounding traffic in high-tech ways, the good old rearview mirror is still a dependable way of letting you know what's around you.  There are usually 3 on each vehicle, 1 attached to the windshield inside and 2 attached outside on each of the front doors. It's important that they be adjusted properly before you start driving (not while you're driving). Experts say the windshield rearview mirror should cover the area behind the vehicle while the outside mirrors should not simply duplicate that view but extend it to the sides, where blind spots normally are. Your rearview mirrors must be able to hold the positions they're adjusted in; it there's play in them or they move around, y ... read more

Motor Oil?The Synthetic Advantage (Synthetic oil vs Conventional)

You’ve probably already heard that regular oil changes are extremely important for the health of your vehicle’s engine. That’s sound advice.  But what you might not know is when it comes to motor oil, the real thing may not be the best thing for your engine. There are different types of motor oil: Conventional oil, extracted from the ground and refined. Synthetic oil, manufactured from high-quality base oils and artificially-made chemical compounds. Synthetic oil blend, a mixture of conventional and synthetic oils. The first thing you need to know is that most new engines require synthetic oil.  If synthetic oil is recommended for your car – you MUST use it. For the rest, there are many advantages to using synthetic oil over conventional oil. Synthetic oil provides better protection for your engine while helping it to perform better. Conventional oil breaks down over time, while synthetic oil lasts longer. Synthetics can stand higher temperature ext ... read more

The Walker Automotive Basic Guide To Synthetic Oil

Synthetic motor oil has been around for a long time, and more and more new vehicles are leaving factories with synthetic in their engines. But a lot of drivers don't really know much about it.Let's start with conventional oil – the kind folks are used to. Conventional oil is made up of naturally occurring hydrocarbon chains, which means its molecules are long and have various lengths. Like a pile of pencils, some of them new and some of them used.Synthetic oil is man-made. Its molecules are more uniform and regular in shape – more similar to marbles than pencils. Some synthetic oil starts with a petroleum base that's modified and others are entirely synthesized from other materials.Synthetic motor oil works better in both hot and cold temperatures. It's more chemically stable so it doesn't readily evaporate or break down in the high heat produced inside your vehicle engine. This means it resists turning to sludge, which is a real engine killer.Remember that marbles and ... read more

Got it Covered! (Timing Cover Maintenance)

You may have heard at one time or another about something called a timing belt or timing chain in your engine.  And you may know that if they fail… well, let's just way that there can be some major engine damage.  So obviously, we want our timing belts and chains to be in tip-top shape. One part that helps keep them running the way they should is the timing cover.  As you can probably guess, it's something that covers the belt or chain.  The timing cover protects both belts and chains from dirt and road debris.  Timing belts also need to be lubricated so their covers allow them to be lubricated as well.  They have a gasket that insures a good seal for the engine.  If that gasket breaks or develops a leak, then engine oil can escape, and loss of lubrication is never good for an engine component. Other symptoms of a failed timing cover are leaking coolant, a metallic sound coming from the front of your engine or your Check Engine light coming on ... read more

A Honking Big Jam (Stuck Horn)

At one time or another, most drivers honk their horn at someone who might be texting at a stoplight or not paying attention when they're driving.  But what happens when you tap on your horn and all of a sudden it won't quit? Everyone's looking at you like you're an angry jerk and all you want to do is turn it off! It helps to know the basics of what's happening when you honk your horn.  There's a switch in the steering wheel, of course, and when you press on it, it sends power to a relay which then energizes the horn.  Bingo.  Sound.  When the horn sticks on, one of these parts or the wiring has developed a problem.  With the ear-splitting noise inside your cabin, it may be hard to keep your cool, but do your best to stay calm.  Try pushing the horn several times; it may un-stick the switch if you're lucky.  If not, there are a couple of things you can try. First, if you can, pull your vehicle off the road and into a spot where you're not disrupt ... read more

What Is a Differential and Do You Have One?

With front-wheel drive being so common these days in Wilmot, NH, the differential is just taken care of during a transmission service, so most Wilmot drivers don't even have to think about it. And rear-wheel drive differentials don't need to be serviced for years, so it's understandable that it's not something on the top of Wilmot customers' minds. It's not uncommon for drivers to not know they have a differential let alone know that it needs service. Call Walker Automotive in Wilmot at 603.526.4848 for information about differential service, or stop by our Wilmot, NH, auto center at 3 Deerwood Drive, 03287. To better understand what a differential does, think about our local Wilmot high school track. There are lanes marked off on the track. For the longer distance races, the starting lines are staggered. The starting lines for the outside lanes are ahead of the starting lines for the inside lanes. That's to compensate for the long ... read more

Weather Station on Wheels (Vehicle Sensor Maintenance)

You probably never thought about it, but your vehicle is like a rolling weather station.  It can check the outside temperature, let you know when the roads are slippery and help you deal with rain. And how it does all those things is pretty cool. First, just like any weather station, a vehicle has sensors that measure the driving and weather conditions you find yourself in.  Some of those sensors can control computerized systems in your vehicle to react to the weather.  It depends on whether you have a 2-wheel, 4-wheel or all-wheel drive vehicle how those sensors will respond. Let's start with temperature.  Most vehicles now have a thermometer that measures the temperature outside.  It's usually in the front, and likely will tell you on the instrument panel what the outside temperature measures.  But a temperature sensor will also tell your vehicle's computers to turn on or off certain systems like the heating or air conditioning.  If your ambient tem ... read more

The Turn Signal Mystery (Turn Signal Problems)

Some problems are easy to diagnose on a vehicle; others aren't.  Figuring out what's wrong with a malfunctioning turn signal sometimes fits into both categories.  By the way, if your tempted to just leave your broken blinker broken, remember you can get a ticket for not using them, not to mention you are missing a great chance to communicate your intentions to other drivers on the road. There can be lots of signals that your signals are on the blink.  Does only the driver's side signal not work or the passenger's side? Do your hazard signals work? Do the lights illuminate but not flash? Can you see the indicators on the dash blinking? Do your turn signals turn off after you've finished your turn or do they stay on?  These are all great clues for the technician. Here's one common symptom to take note of.  Your signal all of a sudden starts blinking much more quickly than it used to.  It could be a simple as a burned out bulb.  But there are many differ ... read more
