Automotive Tips from Hill's Auto Repair, Inc.: Alignment Inspection

Uneven tire wear, the car pulling to one side or a steering wheel that is off-center are signs for Bushwood drivers that their wheels may be out of alignment.

When doing an alignment inspection, the service advisor at Hill's Auto Repair, Inc. will inspect your tires for uneven wear as well as suspension and steering parts for signs of wear or damage. He?ll also compare your current alignment with the vehicle manufacturer?s settings.

Your vehicle owner?s manual will have a recommendation for when to check alignment. Of course, this recommendation is based on normal driving. If you have been in a crash, hit a curb/pothole, frequently drive off-road around Bushwood, or notice any symptoms of misalignment, have your Hill's Auto Repair, Inc. service advisor perform an important alignment check.

To Fix or Not To Fix: That Is the Question.

No matter what vehicle you drive, when certain things break, you have to make a decision.  Should I get it fixed now, later or never?  Air conditioning is one of those things.  You can certainly live without air conditioning, but it sure is nice to have on a sweltering day.

Let's say your air conditioning breaks in the fall and you live in a climate where it gets quite cold in the winter.  Should you get it fixed now, wait until spring since it won't get warm until then or maybe not get it fixed at all?

That can be a tough decision.  There are several reasons air conditioning in vehicles break.  One is fairly simple: It could be an electrical problem, perhaps a relay or solenoid is not turning on the system.  It's also a fairly inexpensive repair and doesn't require hours of labor.

Or, the problem is that the coolant has leaked out.  Your service facility can find the leak and replace the parts that are leaking.  With a refrigerant recharge, you're back in business.  The repair costs vary, depending on the reason for the leak.

When air conditioning malfunctions involve a compressor, evaporator or condenser, the costs can be significant since parts and labor add up.  Depending on the age and value of your vehicle, you may choose to simply roll down the windows and live with it. 

Keep in mind that many vehicles in cold climates use air conditioning in winter.  Many vehicles automatically turn on the A/C when you use the defroster.  The A/C dries the heated air it blows on the windshield and side windows to eliminate fogging more quickly.  Outside conditions such as snow and ice can severely hamper visibility.  Add to that fogging on the inside and it can present very challenging conditions for the driver.

In order for all systems to be functioning optimally, a vehicle owner might feel it's worth it for safety reasons to get a broken air conditioner fixed, even if it is done right before the approach of cold weather.  Discuss these options with your service advisor so you can make the best decision for your situation.

Diesel Maintenance for Maryland

At Hill's Auto Repair, Inc. we hear from a lot of people who are excited about the new diesel engines that will soon be available in passenger cars and SUV's. But our Maryland friends are often curious about the preventive maintenance requirements. People may not know that diesel engines have long been used extensively in Europe and Asia. In fact, in some markets, there're nearly as many diesel powered passenger cars as there are gasoline.

Here's who's announced or is expected to announce new diesels for North America: BMW, Mercedes, Audi, Volkswagen, Nissan, Honda, Toyota, Hyundai and Subaru. Of course, the US auto makers will be expanding their diesel offerings as well. Diesels will become a very big deal here in Maryland.

You may ask, why has it taken so long getting to Maryland and North America? There are a bunch of reasons like fuel tax policies and such, but the biggest hurtle was that Maryland diesel fuel had a high sulfur content – too high for the latest generation of highly refined diesel engines. Recent government mandates to remove sulfur now opens up Maryland to the engines the rest of the world's been enjoying for a long time.

Why are diesels so popular worldwide? Well, for starters, diesels get up to 30% better fuel economy than gas engines. And they last a lot longer. And modern diesel engines are refined, quiet and powerful – and there's none of that black smoke we used to see.

Some people may think that diesels create more pollution. But, you need to rethink diesels. Environmental pollution standards for diesel cars and light trucks are scheduled to be as strict as they are for gasoline vehicles. A modern diesel engine is as clean as a gas engine.

Repair costs are similar to vehicles with gas engines. As with gasoline engines, proper maintenance is the key to long engine life and to avoiding repairs. So pretty much what we have come to expect with gas vehicles; coolant system service, transmission service, power brakes, power steering, differential, filters, fuel system and so on. And the payoff for you, if you're the kind that likes to keep your vehicles for a long time, is that a properly maintained diesel engine can last for many, many years.

Tacky or Techie? The Tachometer.

There's a gauge that many vehicles have that says RPM on it.  And there are a lot of people who either don't pay any attention to it or don't even know what it is. Here's why it's a good gauge to know about.

It's called a tachometer, and that "RPM" label means it is measuring how many revolutions per minute (RPM) the engine is turning.  Automotive experts know that a vehicle's engine can be damaged if it turns too fast (revving too high) or too slowly ("lugging" the engine).

A tachometer (sometimes called a tach) is almost a "must-have" gauge for vehicles with a manual transmission; the driver has to manually change gears; the tach helps the driver know when revolutions are in the optimal range.

Some say you don't need a tachometer if you drive a vehicle with an automatic transmission. It's true that most drivers of automatics don't even look at it.  But there are times when paying attention to the tach can help you prevent an expensive repair.

Here's a good example.  Manufacturers now build many of their automatic transmission vehicles with shift paddles.  They let you shift gears without a clutch. That's manual shifting, and drivers need to know they're not revving the engine too high. That's where the tachometer comes in, since it shows you visually when you are in the red zone (RPM too high).

Here's another way the tach can help you: fuel economy. Generally speaking, the lower the RPM, the better the fuel economy. It's not good to go too low, of course, and the tachometer will help you find that spot of maximum efficiency.

You can also spot problems by paying attention to the tach.  When your vehicle stays in first gear longer than usual (higher reading on the tach), then the RPM dip lower than usual after shifting, it may be that your vehicle's transmission is skipping a gear.  Plus, if your vehicle's RPM go up but your speed doesn't, it could mean your transmission is slipping.  Either situation should be checked by a trained technician.

If your commute takes you down some long grades, you might like to put your vehicle in a lower gear to help slow down the car (and not burn up the brakes). Having a tachometer keeps tabs on when your engine is revving too high.

So, consider the tachometer a "bonus" gauge.  It's one more helpful assistant that can help you spot and prevent problems in your vehicle.

Automotive Tips from Hill's Auto Repair, Inc.: Tire Replacement Overview

Tires are an expensive purchase, so knowing when tires should be replaced is important for Bushwood drivers. Tires will just wear out with normal use. The depth of the tread on your tire determines how well it will stop, start and steer – especially in wet conditions. 4/32th of an inch (3.2 mm) of tire tread is considered a safe amount of tread.

Uneven tread wear can be a symptom of other problems, and simply replacing your tires will not prevent the same uneven wear from happening to the new tires. At Hill's Auto Repair, Inc. in Bushwood, we can inspect your tires for excessive or uneven wear. Unusual wear may lead to further inspection of steering, suspension or alignment problems. We can help with necessary repairs and with getting you the right tires for your needs.
