I have a 2004 Pontiac Aztek that is running hot. It has yet to overheat (gauge in the red or dash warnings) but the dash gauge has been to the dot before the red zone more than once. It occurs mostly on hot days in traffic when it is stop and go. Extended highway driving seems to help it down some but will still fluctuate a bit. When I watch it in the driveway the temperature gauge keeps climbing but the cooling fans do not come on unless I turn on the AC. This is typically a wash on the temp gauge as the engine works harder but the fans are on. Thoughts on how to diagnose?
have the same problem?
