Having problems with your 2001 Cadillac DeVille ?
I have a 1999 Cadillac Deville. It is running hot and causing my antifreeze to come out the overflow pipe. My fans are not working either. I checked the fuses, radiator cap, all hoses, and replaced the thermostat. My starter relay is good also. None of these has fixed the problem. Does anyone know what could be the problem?
Sounds like you may have a head gasket problem. These engines were known for having head gaskets go bad which would pump engine exhaust into the cooling system causing it to overflow
