One of the local stations aired a consumer alert for owners of GM
vehicles with DEX-COOL. From lurking here I was aware of the intake
gasket problem on the old body trucks with the 5700 engine. Because of
this I changed the coolant at the coolant at the 50k service ('02
Sierra) just to be safe. I never knew the problem was so widespread nor
was I aware there was a class action suit in progress.
According to the article GM is telling people to call their local dealer
to get change intervals specific to their climate and terrain. For yucks
I called mine and they played the "That's news to me" card and said do
whatever the manual says.
I haven't been reading this group since I ditched Roadrunner (dial up is
a bitch after broadband) but this story really caught my attention and
thought at the very least I could get thoughts from the pros out there.
