This just happened to me on Jand 12 09, I was driving back from the store turned the heater on and it was blowing cold air. Noticed the engine temp gauge was rising the vents would blow hot air then the engine would cool and this repeated till I got home when the vents no longer blew hot air. The dex cool was low I replaced it to the over flow tank ran car again and the temp continued to climb. I opened the pressure cap and the fluid wasnt over the top of the radiator cooling fins. The fans turned on and off intermintally. No fluid moved from the holding tank none visibly. No apparent leaks that can be seen with the naked eye at night on the street corner with a work light. Never smelt the radiator "smell" from the vents
have the same problem?
