Cadillac DTS Problem Report
Cadillac 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.
Leaking oil; plastic gasket needed to be replaced in Jan. 2015. Leaking oil again on March 5, 2015. Plastic covers that cover the gasket needed to be replaced. Replaced them on March 11, 2015. Car would not start on the morning of Sunday, March 15 after 6 hr trip to Madison, WI. Currently, at a Cadillac dealership. They still haven't discovered the problem. Battery and alternator are fine. Car is not firing correctly. Help! - Visitor
Turned on the defroster on a rainy day. Could not get the windows to defrost, only cold air from the vents. Took the car to the mechanic shop. They found the head gasket problem and put the car back together. I contacted the dealer, and am taking the car to them for warranty repair. - Visitor
