Thanks Matt, am glad that Prestone treatment worked good for you--- and believe me, I would luv a quick simple solution. My Problem is that I'm a fanatical direction-following over-doer from way back--- and if it ain't done by the book I ain't gonna' sleep well at night. (some people in my trade sometimes hate me for it)FWIW thinking back it was the prestone 10 minute stuff they had me use. They just had me do it for 30 minutes to really break it down.
You might call a lube place. It only ran me $100. You could get there just buying all the supplies trying to do it yourself and you have all the crap left over in a bucket or two.
And anyway, the GM tech article says other flush products are not reccomended for this Dex-cool-mud-problem so I'm taking the long, hard road home... and when I finally gets there, I know I'll be sleeping well.:wings:
