Hello Sheri, The most important item to check is the timing belt, if it hasn't been replaced yet you should think about doing so. The other is to make sure the radiator hoses and heater hoses are still alright. A burst hose can lead to overheating and destroy an engine, so be sure to have them checked. Hi Eric, reading about timing belts makes me wonder. Could you please explain this.
Timing chains require lubrication and therefore they tend to cost more to build into an engine.
Also chains tend to be noisier, especially if they run on steel gears which would ensure longevity. A number of engines run steel chains on nylon gears to silence them but the gears fall apart eventually. I own a 1997 Ford Taurus. Sometimes when I'm driving the interior light automatically comes on. Hello Cliff, The door switch or the wiring running to it is faulty, it shouldn't be too expensive to fix this problem.
