2002 Cadillac Seville STS ProblemsCoolant Leaks From Water Pump and Radiator
The water pump and/or the plastic side tanks on the radiator may leak causing a loss of coolant. The engine may overheat due to coolant loss. Continued coolant loss after external leaks have been repaired could indicate a blown head gasket.
Overheating of the engine may cause the cylinder head to expand, severely straining the head bolts and damaging the threads in the engine block. This commonly results in a blown head gasket. Our technicians tell us the engine block threads must be repaired before the cylinder head is reinstalled.
This powertrain control module (PCM) may develop a fault with its electrical ground location at the front of the engine block near the starter motor.
