I have a 94 3.0. I just had the motor torn down and the head, intake, timing, and valve cover gaskets replaced. One of the head gaskets was leaking and the coolent would start boiling. Well its still doing it. I drove it 4 miles, the temp was above the L on normal and was working its way to H. I turned off the truck and the coolent started boiling like crazy out of the resivoir and it was steaming like crazy. There was enough pressure that there was coolont forcing its way out from under the radiator cap. I tried parking it on a hill and getting the air out of the system but it didnt seem to help. Whats wrong with this thing. I cant find any leaks. It has a new thermostat (3rd one in 4 weeks) it makes no sense.
