I have an 89 gta, my ac and air pump are mounted on the passenger side of the car. I would like to eliminate both of them along with the bracket and the tensioner. Any of you guys do this?

If so do you have any pics? Or know of someone that has an eliminator kit?

 

do a search....

gm sells a a/c delete pulley so that you can keep your existing setup or you could simply get a smaller belt or you could go with a march pulley system if you want to go a little custom

 

If you want to keep the serpentine then you have to have a tensioner. The brackets on these cars do not allow for adjustability in any other form. You could go to a V-belt system, but that's the only way to eliminate the entire bracket, and if you keep the bracket and tensioner then you need an A/C delete pulley to route the belt where the tensioner will work.

 

Used serp setups are cheap, I wanted to do the same thing but fabricate some kinda bracket for the tensioner to work, perhaps cut off the AIR pump section of the bracket n use the a/c delete pulley in the AC slot. Not sure if the bracket will be stable enough if u cut the bottom half off tho, I've snapped bracket bolts before.

 

okay i'm sorry if i was unclear in my post.

i'm going to get rid of everything on the passenger side of the motor, the air pump the ac compressor, the tensioner, and the bracket that holds everything.

I was wondering if there are any pioneers out there that have done this. Or am i the first. I have a plan of what i want to do but if someone has done this better i would like to incoporate their ideas with mine. if not then i will proceed with my plans

I also want to keep the alt and power steering in the same place on the drivers side.

thank you all for time in reading the post

nitro you seem to understand what i'm dealing with.

if nobody has done this i wonder how many 3rd gen owners would like to.

 

You weren't unclear in your first post. The fact is as The Great J posted, you *need* the tensioner in the factory serpentine system. Without it, you cannot adjust the proper level of tension on the accessory belt.

Typically, what is done to eliminate the AC is to install the factory AC delete pulley, which you can buy from GM.

The smog pump is usually deleted entirely and the belt itself re-routed, and a different sized belt is then used.

If you do a SEARCH you will find the proper belt size and pulley routing.

 

how much is the pulley? how much does the a/c weigh? any improvement in HP? basically what are the advantages? i never have used mine anyway...

 

at least a 30 horse gain...........have to use march pulleys though and nothing else.

good luck to ya, but remember, if you do try to modify your belt system, the stock water pump on the serp belt cars spins counterclockwise, it will not correctly work if you change direction, so if you keep your w/p , the serp belt HAS to run smooth side to the pump

 

Like I said it can be done...it's been done before. It just requires going to a standard-rotation water pump and a V-belt system. You simply can't run the serpentine without the pass. side bracket, tensioner, and A/C pulley.

 

is it really a 30 horse gain?!?!!? how did the non a/c cars work then? shouldnt i just be able to get a pulley off of them? anyone have any pics/diagrams?

 

You do not need a the tensioner serp set up. They put the serps on the long side of the belt to prevent the belt from jumping around and then eventually working it's way off one of the pulleys. by eliminating the passerger side components yes the belt will have to travel on the open face of the belt to spin the correct way. I have already taken that into account.

thank you "TheGreatJ" for stating that this cannot be done. I will do it with very little fab work hopefully something that will cost me less that $100 for the whole project. I will not be using any v-belts.

 

Then do it. And I want pics. I also want to know EXACTLY how you plan to set the tension on a serpentine belt without a tensioner. Keep in mind...a serpentine belt (being longer than a V-belt) is very susceptible to stretching over time. You can't just put it on tight and be done with it, it'll work itself loose before you go 200 miles. A tensioner doesn't just hold the belt tight, it tightens it automatically as the belt stretches. That's why they used tensioners from the factory and that's why you can't do it reliably without one.



I'm sure you can do it. You can DO anything. But as a professional mechanic I can tell you that it won't work.

 

Rippin92RS.....to run the serpentine with no A/C you just need to get a delete pulley. I think you can still order them from GM (ask for the A/C delete pulley for a 1LE car) and from what I've been told you can also use the delete pulley from a non-A/C Astro van.

 

AC Delete Pulley PN#10115875 GM price is around $60 but try GMPartsDirect.com they say its $33.45 + S&H but they list it as a Water Pump Pulley - but the GM dealer I called confirmed that PN# is a 1LE AC Delete pulley.

And yes you need to tension the belt somehow - which is why I was thinking of AC Delete Pulley/Tensioner/Cutting off half the passenger side bracket - I can't imagine how you'd tension it any other way, but if you can think of something, I'd like to see it - I can't warrant spending $600 on a March setup when a used GM setup is $200 including all accessories and can be powdercoated for like $75 bucks. Although, the March pulleys do look incredibly nice, one day I may upgrade, but I'm way over budget on this drag car as it is so cutting a few corners here n there won't hurt.
