Smog Pump delete 88 T.P.I. IROC Vert
I am doing my research on deleting my smog pump that locked up and has engine making whinning sound. I was told I could remove the pully and just change the serp belt. I will eventually change the pump (keeping stock look) but not right now. I don't want the delete pully if I can just change belts.
My question is what exact belt part number do I need for my particular engine? Dayco 968K6 or 935K6. Also which belt routing method?

Another alternative is to take the pump apart remove the vanes so it no longer pumps air and regrease the back bearing with wheel bearing grease. I did that to mine and 2 years 2500 miles still spins free, It makes the pump into a simple idler pulley.
