Tip of the Month


There are many things that can cause an engine to run too hot or overheat. The 5 most common are:

Low Coolant Level from a leak in the cooling system.
Bad Thermostat
Plugged/Restricted Radiator Tubes
Cooling Fans not working
Head Gasket Problems.

Other causes can be damaged or missing air dams in the front of the car, leaves or bugs blocking radiator, slipping water pump impeller, too lean of fuel mixtures and camshaft or ignition timing off.

When that "TEMP" light comes on or the gauge goes into the red it means the engine temperature has reached a level that may cause
serious engine damage such as cylinder scoring, engine seizing or head gasket failure. If all possible do not drive the vehicle in this condition.

It is possible for the engine to run hotter than normal but not enough to turn on the temperature light, extended driving in these conditions can also cause premature engine wear or head gasket issues.

It is always a good idea to check coolant level periodically and replace the thermostat every 5 - 6 years.

Overheated car

If your car gets too hot when driving slow or at stops but cools back down over 30 MPH you probably have a problem with the cooling fan. Overheating when on the highway but OK in town can indicate radiator, thermostat or engine problems. This all assumes coolant level is full. Extended driving when the engine is running too hot can cause head gasket failure or engine damage.

The best preventative measures is to flush coolant regularly, replace thermostats every 5 years, have coolant level checked at every oil service or anytime the engine temperature seems higher than normal and have the cooling system inspected twice a year.

Caution for those adding refrigerant to your own car

Many of the cans of refrigerant you can buy off the shelf contain a sealer. Using sealers can be harmful to your air conditioning system.
Not only will the sealer most likely plug up a key component in your A/C system and cause compressor problems, you many never be able to have it repaired at a qualified A/C repair facility.

A/C stop leak

That "sealer" can damage a $4000+ A/C recovery/recharge machine at a repair facility and once it is detected in the system they will refuse to service your air conditioning.

Automotive Recalls

We often hear about auto recalls when they become big news, but recalls happen quite often and are not always publicized. Many cars running around out on the road have recalls that have never been addressed.

For those who bought used vehicles or have moved since a vehicle purchase, they may not get a notice.

How do you find out if there is a recall on your car? Go to Carfax and enter your make and VIN#. If your car is not listed you can check with a dealer or go to National Highway Traffic Safety Administration or NHTSA.

Millions of drivers could be endangered by operating vehicles that have been recalled but have not been repaired, according to an investigation conducted by Edmunds. They found there were at least 2.7 million vehicles listed for sale last year that still were subject to unfulfilled recalls. There are no laws that require a car's owner to notify a potential buyer that the car being sold is the subject of a recall. More about recalls and 14 of the largest.starbar.gif

Ignoring that Check Engine Light
Check Engine Light When the first GM cars with onboard computers and diagnostic capabilities came out in the early 80's, they could recognize a limited amount of problems and could store less than 20 trouble codes. It's not unusual for an average car today to recognize and set 125 codes or more just for the engine and transmission.

Then there is Anti-lock Brakes, Traction Control, Air Bag, suspension and other systems that have their own codes.

Some of these engine and transmission codes are for problems that usually won't cause problems we notice while driving. We often hear, "that light has been on for years, I don't worry about it anymore" or "Since this is a minor problem, can I continue driving it and not fix it right now?"
Unfortunately you only have one check engine light. If you ignore the light because of a problem that doesn't seem to affect the way the car drives, something else might crop up that will cause big problems and you may not know until it's too late because the light is already on.

Some problems that the light can come on to warn you about can cause poor mileage or be a warning that you may be left by the side of the road soon. Other warnings can be about things that can cause catalytic converter, transmission or engine failure.
