Hi, me again,
Belay that last post, did some research and talked with son and he changed belt his last couple days off. New belt was really tight, but seemed to settle in. Our repair guide had 4 bolt crank pulley with 10mm bolts. The xfi had 5 bolts at 8mm so my prep of required tools was found to be lacking. But car running well and know he will be much happier maintaining his current mpg rather than moving on to something else.
