My 91 LS Sedan is dying
Keep in mind the fact that I have replaced the radiator, hoses, thermostat and all sensors envolved with engine temperature prior to having these problems. My car started over heating one day then the check engine light came on. I added a little less than a gallon of distilled water to the coolant when I saw that it was low. This seemed to solve the problem because I drove for about an hour and a half with no overheating. Later the same day I start the car and it starts overheating after about 5-10 minutes and smoking (steam I beleive). I drove about a mile or two then stopped and refilled the coolant because the car was overheating severely. I was able to make it home but I left a trail of coolant on the ground which seemed to be coming from the exaust along with a lot of white smoke. I could find no sign of coolant leaking from under the car at all, only from the tail pipes. The next morning my car would not start at all.
