Re: Intake Gasket Failure Question

Nice dexcool article you mentioned.

I have a question about
coolant recall for my 2000 Buick regal (LS, nonturbo).
I have been changing dexcool every year and it has 65000
miles. GM is sending me recall notice every 3 months
to care recall. The recall will expire in July 2005.

My question is since I have been changing coolant
regularly and no overheating problem, do you think
I should still take the care to delaer or just ignore the recall.
And if you can explain what's in the recall besides
tightening the bolts.
