Engine Cooling problem
2000 Cadillac Deville V8 Two Wheel Drive Automatic 107700 miles
I have a 2000 Cadillac DTS. It seems to overheat only when I go over 80mph. I have had the radiator replaced and the coolant reservior. I have taken it to a mechanic that has tested the engine. He said the head gaskets are going bad according to the test.
I have been doing alittle research on an alternative repair besides replacing the head gasket. So my question is, have anyone had any experience with Thermagasket in a northstar 32 valve engine? And what was the outcome? Im afraid if I use one of these products, it will clog something up.
And which product would be best to use?
have the same problem?
