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.

    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.
