I don't know about belt size. When I removed my smog stuff and installed underdrive pullies, I had someone hold the tensioner out all the way while I routed the old belt through the system. I then cut it to length and measured it to find the correct size. It hasn't squeled on me yet, nice and quite.

MAC pullies. I've no bad charging issues with them. At night with everything on, the gauge will drop a little bit but it's nothing to worry about. It drops just enough to slightly dim the headlights. Charges normally during day driving.

Mine does that too, and from what I've seen yes it is loose that is why it squeals.

I've watched it during startup and that sound is the belt actually coming off at the tensioner my car only seems to do it when it is cold even had the belt come off when it is cold twice now. But after it warms up it doesn't seem to be a issue.

do you have a lot of play? was your tensioner totally expanded when you took your measurement? if you you gotta take more out so the tensioner put some tension on that belt...

To be honest, I don't know...LOL I tried the 89" belt and it was a bit loose. So I measured the size using the old belt and got me a new one. Since the new one, it hasn't made any wierd noises.
