A week ago my car overheated and the heat was cold. I replaced the thermostat, antifreeze and bled the air out of the system. Everything seemed fine and then today, a week later, it overheated again. I was able to drive it home, but the temperature kept going from 1/4 to 3/4 on the gauge and alternated back and forth every thirty seconds or so. When it went down the heat was hot and when it went up the heat was cold.
What could this be another bad thermostat or water pump?
Thanks for your help!
have the same problem?
