Celica Forums General Discussion General Overheating

I replaced the radiator and AC Condensor and thermostat and still pegs hot. Have No leaks...

1. If it overheats mainly while stopped and idling that indicates a clogged radiator on nonfunctional fan.

2. If it overheats mainly while driving at speed that indicates it is producing too much heat for the cooling system to handle, which may be due to a head gasket leak or bad timing problem. If the radiator was replaced it is possible that too small a radiator was installed.

Good luck!

Probably air pockets in the coolant system. You have to let it bleed out air pockets. Happened to me when I had coolant flush. Temperature indicator went above normal.
