Does anyone know what size serpentine belt do I need to eliminate my smog pump? I am putting headers on next week and need to know to know what size I need. Any help is appreciated.

 

I think nobody answered because it really depends on the car and what size pullies you are running.

General answer, it will be a few inches shorter than what you run now.

How to test:
remove stock belt and run a string around the pullies in a config to eliminate the airpump, then measure string.

realworld:
By smaller belt and try..
if it doesn't quite fit, trade for another belt.

 

I have no smog and no ac ,ac delete option I have a 96.7 inch belt,It s a weird size but thats what I got from auto zone.A 96.5 will also work.I went back and forth to the store about 5 times it sucks
