Question about 1998 Cadillac Seville
Suggest you look on the drivers side of the engine in the front, there is a black metal guard that covers a pulley that drives the water pump. Make sure the belt is not broken and that the water pump turns freely. Have the cooling system checked for exhaust gases, That is the way to check for blown head gaskets. Is there any coolant in the oil? The Northstar engine is designed to shut down cylinders one at a time to protect itself when overheating. Hope this will help you.
