Why is the service bulletin specifically for the 95/96 airpump removal? What about 94 owners that want to remove the airpump? Can they do so without failing an emissions inspection since the sticker is for the later years?

I don't understand GM's reasoning? (What else is new?)!

Hi Dan,

I remember seeing this question before. I don't recall the exact details, but the answer had to do with a 7 year issue - the 95s and 96s, at the time of the SBs issue, were within the 7 year time frame. The 94s were not, so the bulletin excluded them. I think is a liability issue more than anything else.

At the time, NO 94s were still covered under 7 yr/100K mile emissions warranty. Thus, GM didn't bother.

BTW, did this delete this past weekend, using the cermachromed header caps (on my Tri-Ys of course) from GForceSS. Worked like a champ, and that engine bay looks SO much cleaner without the AIR pump :D

Uh, there's another hundred thousand or so non-Impala B-bodies out there


Someone already got the answer right - it's the whole 7-year issue with the EPA. This is the same reason that the warranty coverage was extended on the EGR valves (no, it wasn't because GM actually cares about their customers ;) ).

Ditto what Ed said. It really does clean things up! I've never owned a vehicle where I could see the front of the block! I did it the anal way, and took the A/C compressor loose to remove the cross pipe. I even put a washer on the stud, to replace the standoff on the tube, to keep the compressor aligned. It was a PITA! I got plugs for $1.50 (as seen on 9C1.com) a peice, and everything fits & looks great!! Best of all, I have a hood light now! By the way, did anyone else find a tag stuffed into the soft plug hole behind the AIR pump bracket with a 3 letter code on it???

The rest of you guys are simply riding on the coattails of the 6303 '94s.
;)

Makes sense, but what about emissions testing for 94 owners that have removed the airpump? I have a customer who wants to do this but is afraid of failing a visual. What do you guys think? He could obviously install the new sticker but does the sticker list years authorized or not?

The sticker I have, is simply a statement regarding the deletion, and the TSB #. Nothing else. There's a picture of it on the b-body site.

I removed my airpump and accesories prior to emmission this year. I was talking cars with the inspector and when he poped the hood for the visual stuff he noticed the air pump deletion and I happily pointed out the TSB sticker ;). he then looked up in his "book" then looked @ me and smiled and closed the hood. So I think he knew, but did not care. Hell he did not even take the wheels off the car to check the brakes since i had expresed my dislike of the use of "torque sticks" on the impact wrenches. But of course on our cars it is fairly easy to inspect the brakes w/o pulling the wheels.

But I have kept all of my airpump stuff so I can install the pump and make it look installed if I had too to pass inspection.

Here's a good Q for all of you.
How about doing a delete on a '94 with a '97 Z28 LT1. I live in the Chicago area and have to go get it passed again soon. If the motor is newer should I not be able to do this delete and pass?

According to the Feds, you need to retain all the '97 Z28 emissions equipment to maintain legality. However, if you want to be slightly dishonest, call it a '96 B-body motor if you're running an OBDII PCM or a '95 B-body motor if you're running an OBDI PCM - they probably won't bother checking block numbers. Either option will allow you to delete the airpump.

unless they actually know that the most obvious difference is the aluminum heads.
They never even popped the hood last time, however I was still running the stock motor, but it still had a 'loud' exhaust.
Nick- it's on the driver's side, front of engine block under the coil. Has a few black rubber hoses coming out, to exhaust manifolds and one to the airbox.

I believe that you can legally run aluminum heads on a B-body motor. If not, there's always black grille paint :D
