I know this is for grand prixs, but still worth looking into.

now all we need is to find one for a Bonneville.
I still don't think it would be warranty work though.

Yes, they are posted, but what do we do with them from that point?

Sure, we can have the backing of that website, and others, but it ultimately falls on GM to cut the check as a reimbursement.

Heres what I was able to find out...

So this would not be a recall. Its just to help the dealer service dept. perform an updated repair.
NHTSB would have to issue a campaign recall for this to happen.

Right. But my years in manufacturing tell me that a part number does not change unless there is a specific NEED to diferentiate it from the old one. It costs time and money to create and change a part number.

Usually a part will get revised and no p/N change. But if a change were drastic enough, a new part number is usually needed. See where im going?

Thanks very much for the info Jay. I had my upper intake manifold replaced in June of 2003 when my '98 Bonneville had 43,000 miles on it. Now today of all days, the very day you posted this info, I noticed my coolant is empty once again. I've taken it back to the dealer and they're looking at it as I type this. They've already called me to say it appears to be the intake manifold again but they're going to check further.

So if I understand correctly, last year when they replaced it they used part # 17113136 (this is the # on my invoice from last year with a description "manifold 3.265")

This time if it needs replacing I should verify that they use part # 89017272 (Upper intake manifold kit) and # 89017554 (Upper intake gasket kit.) These numbers represent new, redesigned parts that should hopefully fix this mess. Correct?

Then once it'* fixed and running again all I have to do is see about getting these repairs reimbursed somehow. Last time it cost me almost $700. I cannot spend that again. My engine still has only abot 53,000 miles on it! Thanks again for the info guys!

Just a couple of weekends ago, I had my Upper Intake fail. The guy at the dealership said that the Lower Intake he also sold me was a brand new design (within the last 6 months).

Don't know if this info actually fits the conversation... I'll post part numbers from my receipt later

So here'* an update:

The dealer called back and said the problem is indeed the upper intake manifold again. Surprise, surprise. The first one melted after only 43,809 miles and the second one at 52,562 miles, a mere 8,753 miles later. This is unacceptable and it makes me steaming mad knowing that GM knows this is a problem yet refuses to acknowledge it! After this experience I really don't see how I could ever buy another GM again.

But the good news is the dealer agreed with me. Their records confirmed that this was the second time they're replacing it and even though it was beyond warranty they replaced it for only the cost of labor. So it cost me just under $200 this time. And they stayed late to get it done so I could have the car tomorrow for Thanksgiving.

And for anyone interested, my new invoice does reflect the updated parts, # 89017554 (Gasket KI 3.270) and # 89017272 (Manifold 3.265) that were mentioned in the above service bulletin.

Someone in another thread mentioned they recently received a full reimbursement check from GM for their repairs. Maybe I can track them down and figure out how they got it. In the meantime I think I'm going to research Ford Mustangs or Dodge Magnums.
