Heater blowing Cold Air/Over Heat
I have a 2001 Ford F150 SuperCrew V8. The last couple of days my heater will cold and and the guage will start to overheat. It doesn't happen all the time but is hit and miss. Generally if I turn the heat off the guage goes back and blow hot air. Sometimes I can smell coolant when I get out of the truck and have seen splaters around the resevoir.
Any ideas? I am hoping it isnt a head gasket.
