I have a 1989 L03 TBI car with the power steering, and altenator on the drivers side the AC, and smog pump on the passenger side...I want to dump the smog pump, and not use a delete pulley (If that is possible) I have seen a couple of pics of belt routing, but have not seen one like my setup...Will someone PLEASE post a pic, or drawing of the correct way to route the belt to eliminate the smog pump....I looked at it for an hour today, and could not for the life of me figure it out.....If there is a sticky, or tech article on this I have not seen the one for my setup.....I did see the TPI one, but mine is not like that....Thanks for any help on this issue........Tom

it is pretty easy, I dont' have a good pic.

From the AC, the belt goes down and below the crank pully (ribs line up), it goes almost all the way around the crank pully, then over the top of the water pump (flat side meets water pump, over the water pump, and down and around the PS pump, then up to the alternator, and over.

I don't know if that describes it all, it was the best I could do without a pic. Also, your stock belt won't work, you will need to get a bet that is a hair longer. IIRC i used like a 96.5" or 94.5" belt. It has been a long time since I had serp belts though.

Dewey, thank you very much..I will print this, and read it while I look at the car.....How long have you been runnig like this?????????? Any problems at all????Meanwhile anyone got a pic?????

This should help. Do a search in the FAQ board for "this is what your AIR system looks like". I have a pretty detailed thread in there that I posted years back.

Lets try this again.

It looks like I can't attach duplicate images even if I rename them. Refer to this thread for the image.

Thanks alot Shifty...you are my hero........LOL.....

Dewey316

It runs fine, I ran like that for a couple of years. I have now converted to v-belts with only a PS pump and alternator.

Check the Miscellaneous Mods section in the Tech Articles Tab.
It even identifies the different belt needed.

I heard how hard it was to wrap the headers. But come-on..
Cut off the air tubes & get a welder to close them up.
(Blasting & re-coating would be really spiffy!!!)
That's the least you can do for saving you the big
aw-s*** on that manifold swap

Gallileo60

Yeah, I might do that...Good idea....I might get those headers on one day...lol...Looks like alot of work....It seems like my whole life is spent under the hood of my car.....Am going to pull the smog pump off Sunday..(I hope) right after the sway bar swap..And man are you right on the Aw **** on the manifold...I never noticed that and ive had the car quite awhile......Thanks for the input.Tom

how is it that you need a longer belt with one less pulley?

xjcamaro89

If you could you might want to just put a delete pulley on they arent that much and bolt on really easy, you dont want to throw a belt, thats a long way for the belt to travel from the crank to the AC unit. Just a thought, but if your going down the road and you loose power steering and amps, then you probably threw a belt.

i have been driving with no ac or delete pulley for over a year now, no problems what so ever

xjcamaro89

AC is different, there isnt as much distance from the smog pump to the water pump, as there is from the crank to the AC if you just take the smog out. Im not saying it will happen, but its a possibility.

91 camaro racer

i didn't mean to say ac, i meant smog pump my bad

xjcamaro89

ok, but in any case, i know for my concious, i felt better putting a delete pulley in

It is ugly as sin, and the look without it is much cleaner......Also, I know we are talking only a pound or 2, but 100 pennies will make a dollar.Another reason is, it is alot easier to work on some things, when there are less things in the way, BUT the most important reason for me, is I just dont like the thing...LOL..........I lay in bed at night, and think about how much I hate my smog pump...It haunts me...I am a shell of a man because of my smog pump, i've lost weight, and cant sleep anymore..

wahoo

Removing the smog pump is a good idea.
I will do it too.
Just one question...
On these diagrams, if I remove the smog pump, can I use the stock belt with the new belt route or should I change it?

ShiftyCapone

You need a different size belt. You cannot re-use the stock belt.

Ive been running without the smop pump for about 6 months and it works great. Just follow the delete article here and it will be ok.

what he said

Gallileo60

I feel better already.................

Shifty, do you have a part number for the belt that is required for this delete? Any help appreciated.

beatercoprice

Read the tech section guys, I cant remember right off hand but it tells you what belt you need and everything. Getting rid of the smog pump also frees up a few horsepower. Didnt even throw a CEL on my caprice when I did it.

clean92rs

if i remove my smog pump do i have to weld my air tubes shut or put headers on? or will it be fine as is?

RyanEricW

Well you need to plug the manifolds, also need to make sure the cat is plugged too or you'll have somewhat of an exhaust leak. I badly want to remove mine, but I don't want any drivability concerns, or the value of my car to go down.

Gallileo60

Been gone off mine for years, no problem..Just put plugs in the manifolds, and either get rid of the cat, or plug the tube..A shop did mine for me the first time with a "test tube" now with headers it is even better, my 89, and 92z are both like that..

after removing the air tubes and pump, do I need to have the computer reprogramed? I have read alot of conflicting stories.

torque_is_good

nope

How do you remove the egr and diverter valve without the check engine light coming on and will the motor running like crap

RyanEricW

Leave the EGR for better fuel economy...
The egr, recirculates exhaust gas at cruising (light throttle) to improve mileage. The EGR does not affect performance at WOT.
