2001 Cadillac DeVille DTS Q&A
2001 Cadillac DeVille DTS Question: How long will the repair job last for replaced head gaskets?
That 2001 DTS is a nice car. I know you have invested a little bit of money in it but sounds like you have most if the cooling system replaced. Did the dealer tell you it needs head gaskets? If the job is done right and there are no other cooling system issues the repair should last a long time. I will say that the head bolt threads in the block do stip out and often need thread incets installed. If this is needed the repair can be expensive. If you get the repair done keep a close eye on the cooling system temperature information. Do not overheat. - brinkline
