I have a 1990 acura integra and it has been over heating. There was a small leak. The leak was fixed, we put in a new alternator, water pump and replaced the gasket. It started to over heat again due to a small leak. The leak was repared and it was driving great. 20 min later it started over heating again. Whats going on?
I guess that the obvious answer is you might have another leak.
We havent seen another leak. Were just gonna replace the thermostat. If that dont fix it, head gasket next.
"Head gasket next"? - there are ways to determine if a head gasket needs changing, such as a compression test.
