without A.I.R.

sunbiyatch · February 10, 2004

I have a 96 silverado 5.7 350 and i was lookin into gettin edelbrock shortie headers and the description on the jegs site reads as follows:

"1996-98 1500 Pickup, 96-97 Suburban 5.7L w/o A.I.R."

what is A.I.R. I know its probably something simple, could somebody fill me in on what this is?

Air Injection Reaction. It's a system that pumps air into the exhaust stream to clean up emissions particularly when the engine is cold.

I take it that the e.g.r has nothing to do with a.i.r...

I have one on one of my headers

how would i go about finding if my truck has an A.I.R. system?

....or commonly known as a SMOG PUMP. It's going to look something like this;

If your 97 has it, it will be located below the alternator. Look down there past the tensioner pulley. If there is a idler pulley there, you have no A.I.R. If you do the pump will be there.

I have yet to see a 96-up that has the pump, so if you do have it post a pic.

The newer ones aren't driven off the serpentine belt drive. They are electric. They usually quite apparent for about 30 seconds on a stone cold startup.

That's probably why I haven't seen one. It is rare to see trucks around here with the pumps on them anyway. In fact I have only seen 1 88-up equipped with it.
