Hey guys. I’m just about to replace the water pump so need to sort belts.
What size are required for an 83 K20, it has air con, smog pump delete.
The belts are so worn I can’t get any detail from them.

Plenty of YouTube videos to show you how to figure out what belt is needed when you have none. We did the old string method when we moved all the brackets on Easton’s truck. Bought all Goodyear from their site on Scamazon due to the ability to adjust size and length for our relocation of PS pump and alternator for our vintage air install. Had a few misses with the AC compressor belt but with free shipping and returns ended up with a perfect fit.
