Flatrater,
While I seem to have your undivided attention and sticking to the issue at hand, what's your take on Customer Satisfaction Program Bulletin #03034 concerning use of the cooling system sealing tabs or aka "sawdust" tablets.
I know of a lot of GM owners refusing to take their cars in pursuant to the selective recall. Sort of reminds me of the Doctor that performed surgery on you and left something behind and then wants your permission to go back in and remove it.
