does anyone know off hand which size belt it takes to run without ac or pollution pump?

 

You can't remove both without installing a delete pulley. You can remove the smog pump without replacing it with a delete pulley if you follow https://www.thirdgen.org/serpentine , but if you are removing A/C as well you MUST install a delete pulley in place if the A/C - they sell at NAPA for $39. That tech article states a belt size to try, but with every system it's trial and error - I got the belt in the article but had to exchange for a slightly shorter one.
