serpentine belt system - The 1947 - Present Chevrolet & GMC Truck Message Board Network

**pdxhall** · 05-23-2023, 03:10 PM

I've got this serpentine belt system on my truck. it's a 5 rib system and I thought it was from a late 70s truck. I recently discovered that is not correct while I was looking at AC compressors. The compressors for these years have a single groove belt. Can someone identify this system? here's a picture before I installed it.

Those are OE GM 88-94 brackets from 4.3; 5.0; & 5.7l V8 cars/trucks/Burbs.

Those particular brackets are for a smog pump optioned vehicle.

Thanks Scotti, I guess they are a little newer than I thought. I actually modified mine by removing most of the smog pump mount while retaining the strength. This all came about when I started looking at AC compressors.

Yep.... Easy enough to trim away what you don't want or leave it as is. The earlier years (88-92) had more w/o the smog mount cast in.
Earlier/pre-93 version....
