I want to replace my belt tensioner pully on my 2003 5.3 Suburban 1500.
When I took it off to change water pump, I noticed the bearing sounds dry and I do have a squeaking noise coming from the engine compartment, so maybe this is the problem.
I wanted to use OE, but noticed the OE Delco only has a 2 bolt mounting, whereas the one I have is a 3 bolt (same as Delco Professional)
Anyone know anything about the difference, why there is a difference and which is the better part for the application?
