A/C Help

[Chevrolet1698]

The A/C belt in my 2004 Silverado 1500 4.8L snapped recently, and I believe it’s because one of the pulleys seized up. 2 days before the truck was making a relatively loud screech from the engine compartment at startup. The belt was a gator-type and installed on 12/10/17. I’m not an expert at engine repair, so what pulleys drive the A/C belt? And if one of them is truly seized, how do I properly fix it?

AC belt runs from crank pulley to ac pulley only. The main belt drives everything else. I'd look into a possible compressor failure. Check AC belt tensioner for proper operation

Thanks txab. That’s what I’ll do then.

Those AC belt tensioners used to seize up quite often, especially in the salt belt states.
