Report: Coolant Leaks From Water Pump and Radiator
Cadillac DeVille Problem
Engine Affected: 4.6L V8
Average Mileage: 119,783 mi (54,000 mi - 188,723 mi)
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.
