Cadillac DeVille Coolant Leaks From Water Pump and Radiator

(59 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.

i replaced the radiator and water pump about a year ago.i recently replaced the resivour still runs hot at speeds over 65mph .temp is constantly up and down 196 to 245.i have to put antifreeze in at least once a day. -
The crossovers began leaking coolant. When this happens the coolant may mix with dirt from the engine or ground and appear to be oil. Heritage Cadillac robbed me of $1,500 by replacing the head gasket, knowing the crossover gasket was defective. Eventually, Heritage Cadillac replaced the crossover and water pump for another $1,500, only to say my electronic shocks were going bad. It's been a year later and my shocks are fine.

2004 DTS has overheated since I bought it. Many coolant line leaks, replaced all the metal lines and some of the rubber too. Replaced water pump and removed thermostat. The more I do the worse it seems to get! Now going to remove radiator and have it cleaned and leak checked. Looks like someone used JB weld on lower passenger side of radiator? If this does not work, I dont know what else I could possibly do. -
