Hey guys,
I am hoping someone might have an idea of what is going on. I have a 1973 spitfire I have been rebuilding some of you know. Well before I put the car in the garage to fix the rust I changed the thermostat and flushed the system. The car was running really good, temp was about half way after running idle for 20 minutes.
Now that the car is back on the ground and out of the garage it wants to over heat. Today I ran the car for about 15 minutes and it almost went in the red. I am trying to figure out what might of happened. In the garage I changed the heater hoses and also installed a new exhaust header with new gasket.
Tonight I let the car cool off and took off the radiator cap to make sure the water was flowing. I noticed that I didnt see any water flowing so I filled it up while it was running. The next thing I saw was white foam coming to the top of the radiator.
Any idea's what that white foam is and could it be the problem with my over heating? Or any idea's of places to start with the over heating? I was going to by pass the heater core to see how the car runs or pull the thermostat out and see if it ran cooler that way?
Just looking for idea or suggestions.
