Engine Cooling problem
1993 Cadillac Fleetwood 6 cyl Front Wheel Drive Automatic 291000 miles
I have a 1993 Cadillac Fleetwood with over 200,000 miles. My oil pressure light keep coming on even after placing 5 quart of oil. My temperature light comes on and the car start knocking. Can you tell me what could be causing this to happen?
You are losing oil pressure, and overheating. It possibly has a blown head gasket(s), or internal leak that resulted in intermix and corresponding bearing failure. Or it is just tired, and is nearing the end of it's useful life.
