1999 Cadillac Eldorado Q&A
1999 Cadillac Eldorado Question: if head gasket leaks, should you have coolant in the oil?
Not necessarily depending on how bad the gaskets are. A good sign is bubbles in the radiator while running. The worse the leak the worse the bubbles. White smoke from the tailpipe is another, and of course a mechanic can test the radiator for exhaust gas. - ProfessorG
