My dad wants to toss a 3.4 inch pulley on his 02 Bonnevile SSEI, i know its simple like 3 bolts to take it off put it back on, but do i need to put on a new belt, or just ajust the tensioner? how much tension is right, how do you adjust it. ---

15mm to swing the tensioner to lossen belt pulley puller to pull of 3.8 and press 3.4 back on replace belt with stock new belt might have problems with knock though, so he should scan, scan, then scan some more. Maybe get him a 3.5 instead and a DP and it will realy wake up the car ---
