since this link seems to not be working, I have found another online service manual for Chevy. All you need is a Yahoo ID.

I got this from Edmunds, which has a listing for almost all makes. I would post it, but I don't know how the current admin staff feels about linking that sort of thing.
{abe} oops. I meant this as a reply to the other post about online service manuals.
