Hello everyone! I did my research and found out that no one had a question on this. I replaced my manifold on my pass side for a few reasons. While doing so I was planning on removing the smog pump pulley and running a shorter belt. I ordered the wrong size belt (too short) and pretty much have to wait to get a new belt on monday when part store opens.

My question is this. Can I put my smog pump pulley back in place so everything will route properly, but leave it disconnected? Will this chew my belt apart or cause any problems. I feel that it should be able to spin freely without it being connected. I just need a confidence booster please

I'm going to say yes, but I don't understand what your concern actually is.

My concern would be the belt breaking apart or something extremely bad happening. I figured it would be ok though, thanks for the confidence booster!

It ran for years with a belt on it before, what's different now?

Firebird_305

Haha you bring up a valid point! When it is connected what is the purpose? Just to allow 'clean' air on start up? So without it connected but still being in place, it will just serve as a heavy pulley??

It blows air into the manifolds or cat under certain conditions to provide additional air for the reduction of CO and HC emissions. The rest of the time it's venting to atmosphere, just like it is now when it's disconnected.

If you're trying to gain HP, Try installing an electric water pump. Out of all the pullies it has the most drag. Leave the smog pump alone.

Nope not trying to gain horsepower. I replaced my pass side manifold cause the studs connecting the y-pipe to manifold were broken and bolts were broken in the head so I got a replacement one. The replacement doesn't have any connection for the smog pump so I was going to remove the pulley.
I'll worry about HP when I get everything else done

You'll probably have to remove the pump completely. I had to do that on mine when I put my headers on. The headers I used didn't have any ports for the A.I.R. system, so I removed the pulley and the belt rubbed against the pump, so I pulled it the rest of the way off.
