Mitsubishi Repair: Mitsubishi Eclipse 2000, mitsubishi eclipse 2000, poor engine performance


Question
Can a overheating problem cause the engine to go out?

Before a Engine goes out what signs to look for and wouldnt my car warn me by displaying the engine light first or start runing funny?

Tell me about the compression system how is that related to an overheating problem. As far as oil, and water. If there is no oil and water does that cause a mitsubishi engine to go out?

how many miles am I good for before my engines starts to give me problems?


Answer
Delnisha,
Overheating can be very bad for any engine.  Some engine failures are sudden with very little signs.  Some signs like rough idle, poor engine performance, lack of power, and inability to start are all signs of problems.  Though these signs may not always set off the check engine light, but simply seeing the check engine light come come does not necessary mean engine failure is about to occur.

When overheating and low engine compression is occuring at the same time, that typically means the head gasket has blown.  Engine performance can be dramatically reduced, and coolant would be burned off in the exhaust continuously.  Lack of oil and water cause overheating very fast, and are very bad for your engine.  The only things really keeping your engine operating at the correct temperature are the oil and coolant (water/antifreeze mix).  Coolant is circulated around the engine via a pump to maintain constant operating temperature.  Oil has the main job of keeping the engine lubricated.  So, the less friction, the less heat build up.  And oil, too, can carry away heat and help with cooling the engine.  So if oil is rapidly lost, or there simply is not enough oil, the engine would begin to overheat.  And if it got hot enough, the coolant could boil out.  This in turn could get the engine so hot as to blow the head gasket.  And if the engine overheats too long, it can actually begin to melt together.  So you would be left with just a big hunk of welded metal that used to be your engine.  Keeping up with scheduled oil changes and regular coolant flushes are critical for engine longevity.

If all the regular scheduled maintenace is kept on your car, you can easily get 150,000-200,000 miles out of your car.  Most mechanics you may meet will not be driving a new car, because they drive old cars forever since they keep them maintained.  Even those that don't know anything about cars can keep a car running for a very long time.  Your owners manual will tell you when all scheduled maintainance is required.  You should read up on the maintenance schedule and have those items inspected and/or replaced as need.
Good luck!
