My truck is exempt from emssion testing, but all the emissions equipment must be installed. It doesn't have to be working, but must be in place. NC law.
This is why I prefer to use shorter belt rather than eliminator pulley.
I was hoping someone could tell me which belt size would accomadate this.
Thanks

Oh, Ok... I did not use the belt re-routing diagram. I thought with the shorter belt I would be able to use OE belt routing. let me look at that agian... thanks White Max.

Ok, with the new belt route (not using idler pulley) I will be required to remove smog pump pulley for clearance... which I'm not opposed to if this is my only option.
Is there a shorter belt length that I could use with original OE belt route? I'm thinking I only need another 2 - 3 inches shorter.
Thanks

I've tried this also. I ended up getting the eliminator pulley and used my stock belt. The $50 buck cost gives me great piece of mind. Truck runs flawlessly.

did a smaller belt any bypassed it, worked fine for a while then completely threw the bearings in the alternator and almost started a fire due to bypass angle of the belt (same routing found above on another users diagram), I’m putting a pully on to bypass it properly and returning to the original belt size and angle
