So here it is, the enigma that plagues my car; it overheats. Here's a description, I drove the car in traffic for hours one day, no problem. Then, I stopped for approximately five mintues, got back in the car, backed it out, and started down a hill when, boom, the temp went straight up and it overheated. The main coolant hoses into the waterpump were sucked down like a vacuum. I had the car towed home, and started to bleed the system. It all was going fine (although there was way too much air in there) when all of a sudden the Resevoir tank backed up and erupted, at 160 degrees! My car has had this problem it seems since I got it four years ago, thus I haven't been able to drive it much. The problem seemed to dissapear after one bleeding, but resurfaced in the episode I described above. Does anyone have any clue what is going on here? It has been suggested that the thermometer might be malfunctioning, or that the radiator is messed up, or that the head gaskets are bad. I really don't know what to believe.
