So I've seen this term, "Smog delete pulley" thrown around a little bit and I don't understand why one is necessary. I bought my iroc dismantled down to the pistons, serviced everything and put it back together, minus all emissions and a/c... I have two belts running my alternator, powersteering, waterpump, and of course my crankshaft pulley. No emissions pulley, no A/C, nothing... Did I do something wrong? *confusion*

 

It's only needed for single serpentine belt systems, but it's not REALLY needed at all, easy to bypass it.

 

Thank you.

 

whats the easiest way to bypass the smog pump if u dont need the pulley

 

It fills up the empty space left when the air pump is removed....just looks better IMHO.
