i am currently flushing my coolant system of dex-cool.
ive been told here that peak G05 is the way to go for my 97 gtp, since it wont goop up or corrode the aluminum castings. i went to a few napa , pep boys, around here and i didnt see any of that around.
i saw a zerex g05, and a peak "extended life". but no peak G05. just wondering if the zerex G05 is ok i think it said no silicates but id like an educated opinion. the peak extended life said its fine for all engines etc, but didnt say if it had silicates or w/e is bad for my aluminum.
