Wilmot Auto Repair

Name someone you know who enjoys spending a lot of money on gasoline.  Yeah, me neither. That’s because it costs quite a bit to keep fueling your vehicle.   One way to save money on gas is to get good fuel economy, and most of today’s vehicles are designed to maximize your mileage.  But you might find you’re filling up more frequently than you used to and are wondering what can cause your fuel economy to tumble.  Here are a few possible reasons your mileage has been headed downhill. A logical spot to start is in your fuel system.  You may have a faulty fuel injector or an old fuel filter clogged with debris.  Another problem might be oxygen sensors, which measure the air coming into your engine and the emissions going out. An illuminated Check Engine light may be a sign of trouble there. Plus, worn-out spark plugs can reduce your fuel economy.  Under- inflated, or over-inflated, tires can also be a cause. Make sure they’re all ... read more

It’s always more comfortable in your vehicle when you can control temperature and humidity in the cabin. Air conditioning, which is standard on most newer vehicles, is a vital part of that comfort, and a key component of that system is the condenser. The condenser converts the refrigerant gas into a liquid by cooling it down.  There are a few reasons the condenser can fail.  It can start leaking, which is usually caused by faulty seals and tubes, or debris from the road can damage it since it sits in a vulnerable spot at the front of your vehicle.   Another way your condenser can be damaged is when bits of metal are released after your vehicle’s air conditioning compressor fails and are sent into the condenser. In both cases, you will have to have the condenser replaced as well as other components that are part of the system. Here are signs that your condenser needs replacing.  When you turn on your air conditioning, it won’t make the air as cold a ... read more

In warm weather, you want to be in a cool vehicle. When we're talking cool, we don't mean stylish or trendy, but cool as in not sweltering inside.  And if your vehicle's air conditioner stops working correctly, it seems to always break at the worst time—during a heat wave.  Automotive air conditioning problems fail for a number of reasons: Blower motor not working.  No air comes through the vents, even though the rest of the system could be working fine. Refrigerant leak. When the gas that cools the air off escapes from the air conditioning system, your air conditioner can no longer cool off the outside air Condenser and compressor. These are parts of your AC system that compress and expand a refrigerant gas to cool off the outside air. They are fairly complex. When you bring your vehicle into our service center, we'll run a series of diagnostic tests to figure out what isn't working correctly.  The air conditioning system has a lot of parts. There are elect ... read more

If you’ve noticed your vehicle’s ride has lately been bumpy or you’re hearing strange noises when you drive over bumps, you may need new struts.   The strut assembly is part of your vehicle’s suspension system that’s used to absorb the irregularities on the surfaces you drive on. You have probably heard of shocks or shock absorbers.  A shock is a piston with gas or liquid inside.  When you hit a bump, that shock absorbs the blow. Struts are similar to shocks but they also have a coil spring for extra strength.  They’re often used in the front of the vehicle because of the engine’s extra weight.  As you might imagine, your struts take a beating every day.  Eventually, they will wear out, and your wheels and tires won’t stay connected to the road as well as they used to. In addition to a bumpier ride, you may notice your tires starting to wear with failing struts because those tires aren’t in contact ... read more

When you turn on the air conditioning in your vehicle, you expect cool air to come out of the vents.  You depend on it, especially in hot weather, but it can also be important in humid weather when you need it to help defrost your windows and windshield. The air conditioning system has a lot of parts to it.  It has fans and blowers to move the air through the vents into the cabin.  It has parts that take hot air and cool it off. An electrical problem can be as simple as a broken switch or a broken blower motor. The air may not be getting cool because a hose in the system is broken or the refrigerant has leaked out.  Two major components are the compressor and the condenser.  The compressor pressurizes the refrigerant, one step in the air conditioning process.  The condenser takes that hot refrigerant and cools it down. It also reduces the pressure. Because the climate control system in your vehicle is so complex, it’s best to leave the diagnosis to a ... read more

On a hot day, you want your vehicle's air conditioning to work.  When the air blowing out of your vents isn't cold, it's easy to think, "I'll just take it by the shop and have them top off my refrigerant." But while some people think air conditioning is that simple, it's actually not. If your refrigerant is low, something has to have happened for it to be depleted.  Perhaps there's a leak in the system.  Or some hoses or clamps have failed.  If the system isn't evaluated by someone who knows air conditioning, it's possible that adding refrigerant will just be a band-aid solution. It's also possible that contaminants have gotten into the refrigerant, such as carbon dioxide, nitrogen, argon, or air.  Some of those gases do not condense like refrigerant does which can increase the pressure inside the system and strain the lines and other components. At that point, the best course of action may be to have the old refrigerant (with its contaminants) bled from the sy ... read more

Heat isn't easy on vehicle tires, and as the seasons change, make sure yours are ready to take the heat.  Let's talk first about inflation.  Heat causes air to expand, so heat alone can raise the pressure in your tires.  If you are driving on overinflated tires, they won't have as much contact with the road surface.  In that case, it will take you a longer distance to stop. On the other hand, you don't want your tires to be underinflated during hot weather, either.  That can cause your sidewalls to flex.  Friction will then hike up the temperature and your tire can be in danger of blowing from the added heat. Other things can cause problems, such as uneven wearing.  Your service advisor knows the signs to look for and can diagnose where the wear is and what is likely causing it.  Another thing a technician will look for on tires is tread depth and the condition of the sidewalls.  Any cuts, cracks or bulges could be indications that your tire ... read more

Nearly every modern vehicle on the road today has power steering, a wonderful invention that makes steering take far less effort than it did in the "good old days."  Today, we take our steering for granted: until something goes wrong, that is. Most power steering these days is rack-and-pinion, the rack being a metal bar between the front wheels with notches in it and the pinion being a gear whose teeth fits into those notches.  Adding power assist makes it easy to turn. That assist comes in the form of hydraulic fluid that is pressurized by a pump powered by the engine, an electric motor that adds a power assist or a system that uses both an electric motor and hydraulic fluid. Your vehicle usually gives you a heads up that something is going wrong with its steering. Here are a few signs to look for: A humming, whirring, rubbing or grinding sound coming from you engine compartment when you turn. Signs of hydraulic fluid leaking, such as wet spots under your vehicle. The smell ... read more

Here is a questions for Wilmot drivers: What is a cabin air filter?Is it: A filter for a house in the middle of the woods? A fresh, piney scent? A filter for the passenger compartment of your car? Clever you, it's 3.A cabin air filter cleans the outside air before it comes into the passenger compartment. It filters out dust, pollen, spores, bacteria, pollutants, sparrows, exhaust gas and odors.These high tech filters can block particles larger than 3 microns. By contrast, a grain of sand is about 200 microns.Now not all vehicles in the Wilmot area have cabin filters. They are fairly new on the scene in NH. About 40 percent of new vehicles come with cabin air filters, but the number is growing every year.Cabin air filters can make for a very nice driving environment for Wilmot. Your car can be a haven during NH allergy season with very little dust and pollen getting into the cabin. However, like all filters, your cabin air filter eventually gets clogge ... read more

Air conditioning used to be a real luxury in a vehicle, but now it's standard in most.  Your vehicle's air conditioning system is built to last a pretty long time, but like anything mechanical, sometimes it fails.  It helps to know a little about how the A/C works. There's a compressor that pressurizes the refrigerant (you probably recognize the term Freon).  That makes it hotter, so it then goes through a condenser that cools it off.  Then another component takes out impurities and humidity before the Freon goes to a device that makes it lose pressure before it goes to the evaporator.  That's where it gets colder and takes the humidity out of the air. Then your vehicle's ventilation system blows air over the evaporator, cooling the cabin air that gives you such relief on a hot day. Of all these parts, one that does a lot of work is the compressor.  It has to compress that refrigerant and circulate it through the system.  It turns on and off several t ... read more
