Cadillac DeVille DTS Coolant Leaks From Water Pump and Radiator

(17 reports)

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.
