You dont know that Shifty...they have very liberal smog laws here in cali

[vorgath]

uhmmmmm


I thought one could have slight issues with the cat converter if one deletes the entire AIR system, that one should in that case go with a cat with no AIR tube ?

nah.... I know peoples son.

Yes, this will work for the B2L/L98, that's what my car is. Any motor using GMs factory serpantine brackets.

Yes, you need the smog pump in Cali, and in just about every other state. Most of us "know" people. hehe

I'm running a magnaflow cat without AIR.

[codemonk84]

One of the differences in Cali (at least in San Francisco where I lived for a while) was that you could "know" someone (since the inspection is usually done by local shops) and get them to pass you (as opposed to here in WA, they actually have a station setup, owned and operated by the city or state).

yeah u will still be able to use it, those two don't effect your heater controls. the smog pump is for exhaust and the ac is for ac.

I know I'm showing my ignorance here, but why can't U delete both and use a shorter belt?

If it's direction of turning for the water pump, I know u can get clockwise and counterwise rotation WP's.

I may be wrong Zap but I think there is a way if you put a grooved pulley on the tensioner.

Just ordered mine yesterday(A/C delete)

I am goin to weigh the pulley, then weigh all the crap I pull off my car and see how much the difference is...

Will there be less "drag" on the pulley than there is from the A/C Compressor? I would think....

Thanks for the info..

There will be no less drag then when the AC compressor is off.

I orderde both the AC delete and AIR delete pulleys from GM direct and got them in about one week. I went to install them yesterday and I noticed that the Pulley on the smog pump is significantly larger than the one one the AIR delete bracket. I just did the AC delete for now and left the smog pump. Everyone say on here that you should be able to use the stock belt but it looks to me that the belt will be too long if I install the AIR delete bracket. I mean the differnce is significant, like 4" to 6". Is there a difference in the later models 91, 92?

[Brisk]

I too just got my smog delete pulley in and the replacement delete pulley is much smaller then the one I am replacing... Looks like a new belt will be manditory.

[dab2pds]

larry, put the smog delete pulley on. it does look different but works properly with the stock length belt.

[Daniel U]

When you yank the A/C out, do you need the delete heater box for the fire wall or is it just for looks? Will my heater work with out it? Right now I have 2 stubbed out A/C lines where i unthreaded them from the 2 hardlines. Should I cap off the stubbed out lines? Thanks, Daniel U

Yes I could see how the pulley is off to the side of center of the smog pump pulley so the belt should work. UNfortunately I messed (rounded off inside) up the torx bolt head that is behind the smog pump pulley that holds on the tensioner/ac bracket and could not get it off. I assume it is necessary to remove that bracket before removing the smog pump. Now I guess Im stuck with the smog pump which I can never get off.

On the 90 and before model you could do that, but on the 91 and 92, they changed it so that you must have a pulley in the AC position to route the belt properly. I know because I just removed the compressor from Max's car (1990) and put it on mine, 1991. Max's car has the diagram for the belt routing and it shows an optional routing for a non AC car, using a shorter belt. The AC compressor on his car is on the drivers side and the belt tensioner is separate. On my car the compressor is on the passenger side and the belt tensioner is part of the AC compressor bracket. The diagram shows no option for a shorter belt. You could leave out the Smog pump delete pulley, but not the AC compressor pulley.

BTW, the compressores themselves are compatible, Max has cold air now.

[slayer_taunu]

for the AIR delete pulleys, i just want to try and verify if the original part number posted here: 10186167, and the one from the serpentine kit: 10129569 are the same
from gm parts direct, the 167 is $54.23 /w s&h, and is called a water pump pulley. the 569 is $43.11 /w s&h and is called a drive belt tensioner.

if they are the same, i'll obviously get the cheaper one, but since i saw a few people on this post having trouble with the pulley size, i'm curious as to which one is correct, if not both.

[oxiderush]

So, could somebody answer slayer, i'm interested too.

[redsunshine_91]

Heard about the A.I.R. delete pulley at modern day muscle so I went to my local G.M. dealer and he didnt know a thing without a part #. I was origanally going to modify a used A.C. delete pulley from David T's but he didnt have any either.

[Gallileo60]

Great topic...............

[QuietFlight]

if you wanna keep your AC and just delete smog then you may totally take the pump off and just change the belt and accomplish it without buying the delete pulley..i did this and there is a tech article on how to run the belt on the tech articles under miscilanious mods

[Gallileo60]

What will happen to your cat, when the air pump is removed????? Will it die a horrible death??? Will it clog up??? I want to do it, but am a little cocerned about the cat...Thanks, Tom

[Bill/T/D/Y]

OK time ta show my ignorance.(a daily thing for me).If I remove the smog pump on my 3.1 and install the dummy pully(found 1 this last bone yard trip)what else will i have to do??Is there anything to be done brain box wise??This is new to me i'm used to carbed non-brain syatems.Just cut and plug.What about 02 sensors and such??

[Durango_Boy]

Man this thread is almost two years old. I remember looking up a bunch of info on that January before last. Yikes. Oh well...my delete pulleys served me well...lets keep it going.

[Bill/T/D/Y]

well that was no help.LOL.Just playin.

everything will still work

[Durango_Boy]

I don't know if anyone really cares or not, but in my quest for an electrical system that will support a large stereo...I have opted for two alternators. I have found...that on offset clocked CS130 case fits nicely in place of the A/C compressor. Only needed a small mod to lengthen the mounting hole on the outside. Then, I just piggy backed the wiring...and viola...twin alt system.

Very soon. I am waiting for my custom power steering pump pulley to get here, and find the new length belt. Once I have those items I will finish it and post pics.
