RE: Blwon Head Gasket
I bought the car only 2 weeks ago, so i'm not sure how well it was maintained. Its a 96 deville with only 82,000 miles. THe coolaant had been flushed and refilled. I've never heard of sealant tabs.

GM part #3634621...sealant tabs. AC Delco#10-108. A bag of 5 is under $3. These are required for the cooling system each time a flush/fill is performed. You 'might' get away from the gasket problem if you use them...maybe...but anyway they are a requirement.

RE: Blwon Head Gasket
When I had the radiator replaced in my '96, I had called Cadillac dealer and asked about the tabs. The service guy told me that they were not necessary. He said that Cadillac put those in when the car came off of the assembly line to help seal the coolant system until the car was broke in.
BTW, I have read where there is a problem with the head bolts on this year of engine and there is a GM service bulletin that tells what is needed to fix the problem. The problem was with the head bolts stripping out of the engine block. So if you are going to replace the head gasket, you might as well check into this to see if it is really a problem.
