Mercury Rising (Hot Weather Vehicle Concerns)

The heat is on, and your vehicle takes a beating when it is.  Several of your vehicle's systems are under extra stress in hot weather, so here are a few to make sure are getting the care and maintenance they need.

It makes sense that the cooling system is one to make sure is in top shape.  Vehicle breakdowns in summer are often due to a problem with one of the cooling system's components.  Coolant levels have to be up to specs, the ratio of coolant to water must be correct and the hoses, pumps, belts and radiator must all be working properly in order to prevent vehicle overheating.

Summer is also hard on your air conditioning system.  You might find that no air is blowing out of the vents or maybe only hot air is coming out.  Air conditioning equipment is best diagnosed and repaired by a trained and experienced technician.  The problem could be in any number of components, including the condenser, compressor or blower motor.

You may think the battery gets a break in the summer, but heat will shorten the life of your battery more quickly than cold.  Your service facility can analyze the condition of your battery and tell you whether it's healthy or needs replacing.

Tires take a beating in heat, too.  Pavement can be scorching hot, and the sun's rays break down the rubber.  Watch inflation pressure in hot weather, too, since air expands the hotter it gets.  Your technician can check air pressure, tread depth, cupping and other uneven wear and diagnose the source of any problems. 

And don't forget brakes.  One video online says brakes on a car that were driven hard on a track reached temperatures as high as 500°C/932°F.  Heat can reduce stopping power.  A technician should periodically inspect pads, rotors, drums, lines and other components to find a problem before you lose the ability to stop.

Finally, engine oil is really put to the test when it gets hot.  Your vehicle service facility will make sure you have enough oil and the proper kind to keep your engine's components properly lubricated.  Help your vehicle beat the heat.

Muffler: Victim of Winter (Muffler Repair)

So you almost got through the winter until, one day, your muffler started sounding like a dragster, loud and obnoxious.  It's not surprising.  All that road salt and brine can cause rust to punch holes in a muffler, and that should raise a big, red warning flag about the safety of your vehicle.

One big concern is carbon monoxide, a poisonous gas that can drift into your cabin if your muffler is leaking. You've probably heard about people whose home furnaces have leaked carbon monoxide and overcome families inside.  Carbon monoxide can first cause you to feel dizzy and nauseous.  It can even render you  unconscious—even kill you.  So if your vehicle's muffler is leaking that gas, well, it's nothing to mess around with.

Oh, and how about that noise? You may get a ticket since many municipalities have laws against noisy exhausts. 

Your muffler may be making a clunking or rattling sound when the engine's running or it may be spewing thick exhaust smoke.  All of these symptoms are telling you to get to your vehicle service facility soon.  A technician may find it's the muffler or another part of your exhaust system that is coming apart or is busted. 

Sometimes the repair can be as simple as replacing a section of pipe or clamps, but sometimes you'll need to replace more components.  Your service advisor can recommend several different options to try to help you meet your performance and budgetary needs. 

You'll drive out with a vehicle that doesn't sound like a teenager trying to hotrod the family car, is a whole lot safer and sounds a lot less obnoxious in the process.

See the Light (Automatic High Beam Dimmers)

It's happened to all of us.  We're driving down a highway at night and over a crest appears a car with its high beams blazing.  You are momentarily blinded, hoping the other driver will switch them to their low beam setting and restore your vision.

Not only do we not appreciate being blinded, face it; we don’t want to be that other driver, either.  You know, the one who forgets to turn down their high beams.

Why do we want high beams in the first place? They can improve safety when used correctly, giving drivers more reaction time since they can see farther down the road.  But research has found many drivers either don't use them or, when they do, they frequently forget to switch to low beams.  Enter the automatic high-beam dimmer.

The quest for the perfect one began back in the 1950s, General Motors invented something it called the "Autronic Eye." It was a phototube which sat on the dashboard and turned down your beams when it saw other headlights.  While touted as being the biggest advance in night driving safety in 30 years, it didn't work all that well.  But as technology got more advanced, systems improved.

Today's automatic high beam dimmers usually have a camera in the rear view mirror (pointing forward).  When the camera sees lights, software in the system's computer attempts to determine the source of the light, whether it is an oncoming vehicle, taillights, ambient city lights, street lights or the reflection off of a street sign.  It then adjusts the headlights to operate high beams if appropriate or a less-blinding mode if they’re not.

Some automakers are striving to make their headlight systems smarter and safer by developing lamps that can avoid blinding oncoming drivers by means other than simply dimming them. One idea? Splitting the beams so they will block just the portion that shines into the eyes of oncoming drivers.

It's a long way from the Autronic Eye.

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.
