    buying a new/used Caddy

    So if it ends up my heads are bad on my 99, which still crossing my fingers. After reading so much on the Northstar I'm a little intimidated by it now. I really like Cadillac Devilles especially and cant afford a new one, is their a way when car shopping to tell if the car has overheated previously? Once I do this block test on mine, should I be doing this on prospective buys? LOL, well maybe seriously.

    In '00, changes were made to the block casting process, and a switch was made to longer head bolts, greatly reducing the chance if failure.

    In LATE '04, a switch was made to course thread bolts, essentially eliminating the problem.

    Yes, do a block test on any perspective purchase, after plenty of WOT on the test drive.

    Unfortunately your '99 has the worst failure rate of them all. As MC said, you'll be pretty safe with a 2000+ and even safer yet with an '04+.

    Well, just because they have a bad failure rate does not mean ALL '99's will fail. The fact that you made it to 160K is a good sign.

    Get a 05-04 best years no need to worry about the HG issues, and gives some kind of peace of mind
