How easy/hard is it to replace the air pump? Mine needs to be replaced for smog, as well as the solenoid hoses, filter, and check valves. This is what the dealership told me.
I see I can get most this stuff off ebay for a much better price then the dealer, and its all new!
just curious on the work involved. could I do it at home in a day? I dont even know where the thing is located, its not belt driven like the POS on my IROC was. ( I ditched that thing long time ago)

 

It's very easy to get to. It's' in front of the driver's side wheel well. You can get to it from underneath.

 

Thanks, Found it. Didnt know what I was looking for at first.

Next question, what are the interchangable years? mine is a 98 z28.
will a smog / air pump from a 00-02 work as well?

 

unless you live in cali then i would ditch it... maybe the stealership tryin to get some money off of u

 

I do live in cali and smog is due this month

 

If ya need a pump I happen to have one I took off my trans am. If interested I can see if I can find it tomarrow

 

is it a 98-99 TA? i keep seeing different part numbers for the 98-99 and 00-02 models.
I am interested however, let me know

 

mine is a 2000. Yea i have no idea on the part numbers

 

Why can't he just keep all hardware intact but just delete the AIR system from the computer. Since it only works while the car is first started I would assume that by the time he got to the inspection station the AIR system wouldn't even be running anyway because the car is at normal operating temp.

 

I agree unless the plumbing of the AIR system is something they look for during the inspection.

 

All of my plumbing is 100% intact and I bet it would pass their visual with no problem. I was just curious about how stringent CA is.

 

I agree to tune it out. Wont turn a code. The air pump isnt used during driving while youre on teh rollers getting smogged anyway.

 

Its frozen, they DO check, and my engine light comes on because of it.

 

Not to be argumentative but so did mine until I had it programmed out. No more CEL and all items are still on the car. If they do check then how do they check for this? My *** was tight the first time I took my car in for inspection after my computer was "tweaked" but it passed with flying colors, just as the computer tweaking company told me it would do.

 

Yeah, once you get it tuned out, you wont get a SES light, the computer will read that it passed its self diagnostic. And the air pump only runs at start up, not once teh car is warmed up. So it is not going to affect your smog numbers on the rollers.

 

I had all my air pump codes blocked/turned off with ls1edit.
It passed an obddii plug in test after starting the car and letting it warm up for a few minutes and then driving it to the station. The car sat for a week before that. I was afraid it might not "be ready" per the codes but it passed.
It is still working for now but it makes strange noises every now and then so i decided to just program it out.
