How to Remove Smog Pump and A.I.R Tubes
Need help with removing my smog pump and A.I.R tubes on my exhaust as I'm trying to run Hi-Flow cats and a better exhaust system. I want to remove weight and make the engine bay look cleaner. Do I have to get a new radiator? What all do I need and where can I get the A.I.R plugs for the manifolds? Also, I don't want to get a delete pully so how would I have to go about doing that and running a different belt?

inverted flare plugs for the manifold. The air pump has zero to do with the radiator.can run a shorter belt or there are two different bypass pulleys available.

I asked about the radiator because there seems to be a hose from the radiator that one of the pumps attaches a line too. I'll look more at it and figure it out but thanks for the info

Search the forums, lots of info!
ACDelco #935K6 + your Cat converter(s) need a plug of some sort or be replaced.

I may be mistaken about it but I'll look into it when I get back home. It's kinda hard to drive it with my master cylinder clip for my clutch (little plastic thing that attaches the clutch pedal and master cylinder together) keeps breaking and making it where I can't shift gears. Really annoying thing.

Re: How to Remove Smog Pump and A.I.R Tubes
There is no cooling system connection to the AIR system.
You can cap the existing air tubes at the exhaust manifolds with a rubber radiator hose cap and a band clamp. Leave the check valve in place and just cap the end where you removed the rubber hose.
Some have run a shorter belt after removing the air pump instead of buying a bypass pulley. I don't know the belt length needed, but there are many posts about it.
