I have an overheating problem. One mechanic says that the engine is ruined, but it has extremely high pressure building up in the coolent system. Is the engine ruined or do I have to replace head gaskets?

If you have no leaks and the fans work right up front, the problem lies at the headgaskets, the head bolt threads strip out of the block due to overheating. This is quite fixable done it plenty of times. If you fix it have them helicoil them all wheather there bad or not

in my 5 years at caddie never seen a headgasket prob it was always the headbolts

make sure the waterpump is ok along with the belt its on the front head at the right end looking at the motor or drivers side, remove the black bracket to ck it
