I have searched and saw that there is a problem getting everything to go smoothly after deleting the ac. I see there is an ac delete pulley from summit. I have an 89 camaro with 2.8, is there a detailed writeup about removing it all? I want it all gone, including heat. I also have a 98 camaro, which has a seperate radiator type thing besides the normal one, for just the ac...does my 89 have the smae thing? Is it going to be easy to take it all out, and use the delete pulley? Or do I need to do something else? Thanks for the replies, I know yall get this question all the time.

Well my brother has a 91 3.1(i got a 92)..when he replaced his compressor with a delete pulley he went thru 3 belts cuz it was tearin the edges.Even tho the pulley looked true it wasnt so he just uses the compressor as a pulley like me..i took everything a/c related off..everything.

The FIRST rule of screwing with the A/C system is to MAKE SURE IT'S EMPTY AND/OR DISCHARGED. You DO NOT want a cloud of R-12/134 in your face when you disconnect that fitting!
Second, if you have v-belts, you probably need the pulley. If you're serpentine, go out and get a non-A/C belt (with or without AIR, depending on if you have AIR or not). Remove what you're going to remove, then remove the entire compressor, both brackets AND all. There will be 2 holes in the upper portion of the power steering pump bracket, where one of the compressor bracket bolts went through. Remove the rear pump bracket altogether (but leave the bolts in the pump or you won't have power steering for very much longer!), loosen the water pump to power steering pump bracket bolt, and tilt the pump and bracket inward until the OUTER of the 2 upper holes lines up with the threaded hole in the cylinder head. Put the shorter A/C bracket bolt in here (because of the size difference) and tighten the other bolt. Put the belt on and enjoy not having A/C.
BTW, any savings you would get by deleting an empty A/C system is completely negated by leaving the compressor as an idler pulley.
This car is gonna have a turbo, so I want all the space I can get.
I am also deleting all the smog stuff, so I need a writeup on that too. But I guess since this car isn't my daily, I can just go start unbolting stuff.
So how do I know for sure I have everything out of the ac system?
BTW, any savings you would get by deleting an empty A/C system is completely negated by leaving the compressor as an idler pulley.
Thats completely false, first there is no more load on the motor with the A/C clutch disengaged than is put on the motor by an A/C delete pulley or any other idler pulley. Second you would see a gain in 1/4 time and speed (the true test, where as a dyno is simply a numeral display, of the output of a motor, not the overall performance of a vehicle) not by more horsepower but by the 200lb's of HVAC **** he has just removed.
The enviromantally/legally correct way to test the A/C system would be with a manifold set hooked up to both the high ans low side, as long as your mostly sure though you can use a small screw driver and depress one of the schrader valves and see if anything comes out. Dont have your face over it though and wear a glove, that **** will freeze skin.
u do not have to run a delete pully, let me see if i can dig up pics of my build
also see streetlethals thread for a cheap non ac heaterbox option
not my pics

Ok thank you. I just don't know where to start pulling stuff off at? I know the silver canister thing is the condenser i think, I know it is part of the ac. So should I just pull it out and start ripping out everything connected to it? Please help, I'm gonna try for this tomorrow.
That silver can thing is the accumulator... The condenser is the second radiator that is in front of the engine radiator.
And, like I tried to say before (and had a computer error), you do NOT want to keep the compressor if you're looking to shed pounds. That compressor is at least HALF of the weight of the A/C system. At least I think it is, based on what I've removed (all but the heater box and the evaporator because I haven't found a non-A/C box). Another reason you don't want to leave it is because the clutch pulley is a lot harder to fix if the bearings fail, like mine did, which is why I removed it after not having the rest of the crap for 4 years.

Dan...I think imma be deleting the AC this winter...gonna have to have you come over again lol...
BTW check out the DIY Board as i got my computer to connect! I went to the you pull it yard i told you about and grabbed a diff 730 ecm with the atzy code in it. I know i didnt call ya...ill take ya next time. There were like 6 thirdgens there. Anyway It worked! Either way I still want that belt you have if you dont mind. Ill give it back when we delete the A/C stuff as it will be too long.
OK ill stop jackin the thread to talk to dan and contribute to the thread.
If your going to go the route that project 89 is showing im almost very positive that you will need to get a shorter belt. Just a minor thing but dont forget that, espically if its your only car. Been there done that before.

Ok guys. So where should I start taking stuff out at? Do I just take off the intake tubes and then I can pull out the condenser? This is not my only car. My dd is my 98 camaro, this one just sits while im trying to get a title for it. I plan on pulling EVERYTHING from the hvac system. Heat too.
Start at the compressor and unbolt it. Follow the lines to the accumulator and unbolt them. Then you can unscrew the accumulator. Follow other lines to condenser. I didn't pull mine right away but had a 1/2 inch coarse thread brass cap screwed on. Follow all vacuum lines and wires to their end and see if they can be pulled and capped. It's really simple once you get started.
