Cadillac DeVille DTS Problem Report
Cadillac DeVille DTS Engine Overheating Due to Leaking Headgasket
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.
Water pump apparently stopped working while on trip. Pulled over as soon as light came on, but to late. Head gasket blown. No one willing to replace for under $4,000. Horrible resale[wonder why]did not justify the repair. Luxury redefined.
GM knows all to well about the infamous North Star, but that's all behind them...and the bankruptcy that ensued. Not only did we pay for inferior GM products, the salt has to get rubbed deeper into the wound from the bail out. - Visitor
No indications from temp gauge that there was overheating. Nevertheless, coolant leaks from radiator were diagnosed to overpressure in the cooling system due to blown head gasket.
Engine removal was necessary. Total part parts and labor at a dealer was $5500
Subsequent coolant leaks a few thousand miles later. Still being investigated. - Visitor
