My 97 F150, 4.2 V6, is overheating. I have coolant. When I turn on the heat in the cab, the engine will cool down. I took it to the shop. They replace the thermostat and the timeing cover which was cracked. This did not solve the problem. If I run with the heat on it runs fine. When I turn the heat off the temperature gauge goes to Hot. Help
I have a similar situation. Shop said my timing cover broke because it might have been cracked. He broke it. It still overheats. The waterpump timingchain and gears were also changed. Then they said to check the radiator. Im taking it to a different shop tomorrow to check the intake gaskets.
I had my radiator rodded out today. The guy at the shop said it needed it. After over heating the mold clay left in the radiator from the factory loosens , collects and clogs the radiator. Overheating is not my problem now.
