When the car is first started heat is fine (once warms up), then as it sits there on idle the temp gauge goes above half and then the cold air starts. Now if you drive it the temp goes down and heat comes back. I have checked fluid level. Checked for air in system (bleed valves). I can not have a plugged heater core due to it working if you are not sitting idle. Any ideas? Thanks ahead of time.
have the same problem?
