Nothing major. Just the air conditioning belt.

Vehicle: 2000 GMC Sierra 1500.
Motor: 5.3L V8.

I can get the serpentine off, but I'm having difficulties with getting the friggin' a/c belt on. I'm not seeing another belt tensioner to shift to get the belt on so if anyone here has any advice for me as to how to get this bastard on ..

I'd muchly appreciate it. Can't find a manual on these things anywhere as it's one of the most common trucks/work trucks in town.
