I know how to do it, but if it's completley non-benificial I don't want to do it. I always tell myself that I'll just keep it for when I need it; but no matter what, I refuse to use it. Would it help not having the weight/compreser? I reaize it wont free up much hp and that I'll have to do something about a belt once I remove the compresser. Is it worth it or not? I could always sell the parts and buy another mod, like a strut bar or something...

Well looking at it today, it looks like I'll have to come up with some kind of replacement pulley for the pump pulley.. Didn't the 2.4's without ac have a "dummy" pulley in it's place?

I'll give you the best advice I can. Haveing done this before to my older muscle type cars trust me when I say you WILL want it one day. Maybe not for the cold air but the defrost needs to be set to cold sometimes to work. NOTHING worse then not being able to see cause its a hot ass day and it starts to pour down rain and your windows fog up like no tomorrow. Do it if you want but I would recomend against it. It will also KILL any re-sale or trade in value you may want to get for it one day. The little extra weight in a daily driver isn't gonna hurt anything at all.
In short........ Leave it alone.
Semper Fi SAINT. May you rest in peace.
We all know that the thousands of dollars of mods we put on never translate into significant resale value. You can be sure that removeing the a/c will lower the value, esprcially since it was on it from the factory. As for not using it...go ahead, you'll like it.
I could be wrong but didnt some of the really base 03-05 not come with a/c?
You could go to an auto store and see if they sell a belt for a non-ac ecotec.
Just drive it like that and when you need it you can just pop on your old belt.

The A/C compressor wheel just spins freely when the A/C is off (there's a clutch that engages when you turn on the A/C, otherwise it's off and it freewheels).
The only benefits are weight savings (35 pounds, tops) and extra room in the engine bay for running charge pipes for turbo applications...
I'd say... not worth removing it. Especially if you plan on selling the car eventually.
(I've seriously contemplated this myself... what good is a convertible with A/C, when I always have the top down? But... I digress... I kept it...)

John don't forget the defrosters like I said.
And at resail time most people don't mind the mods as long as they're done right. But
no A.C. is a deal breaker TRUST ME.

I removed mine and did not see any performance gains. The -35lbs helps im sure, but I could not see more then a 1 hp gain. I do regret taking it off, we have had a really hot summer and my woman demands AC, I basically bought a new car because of it.

Do you know how fast you were going son? No sir, my speedometer only goes to 110.
Mines off have delete pulley, I am going to just run a belt and sell my by-pass pulley.

alright, you've all pretty much talked me out of it... looks like a PITA anyway.

if you remove the pump that will reduce some of the weight, ples if u run with the shorter belt, it will cause yur pullies to spin faster when accelerating (enabling a bit of a hp gain) the difference in performance wont be dramaticle, but it will be noticable if u do everything right. if you do it heres what u need to do..
1- get belt that does not pull the AC pump
2-remove the AC Pump
3-Remove all of the AC lines
4-Remove the AC Radiator thing (right behind grille)
it will reduce yur weight a bit, more then u would think, if u do it all the right way u should be able to notice a slight difference. i have done it all to my car, and i can notice it. all i do is cruise with the windows down. lol

You wanna explain that part in bold again?
<a href="http://www.lenkorules.com/"><img src="http://members.shaw.ca/jlenko/sig/redsig.jpg"></a>
if you run with the shorter belt, it has been tested and proven to increase acceleration, top speed, torque and hp. of course its not much of a gain in any of the catagories, but it does improve slightly. a belt only cost about 5 dollars for my year, not sure about yours.

Ok, forgive me for doubting you... but I seriously do NOT understand how a shorter belt would do that. The crank still spins the belt (albeit shorter) at the same speed. I fail to understand how it's going to do anything...?!?
I understand how running the track with NO belt would do it... because I've done it many times. Tho not anymore with the supercharger....

Lenko, normally I would never agree with you, but on this one you are wrong. It will and has been proven to make slightly more hp.

Then how is it possible for defrost to work on vehicles that didn't have a/c from the factory? I have an old '88 Dakota with no factory a/c and it clears the windshield just fine.
I do tend to agree that its not worth removing unless you are building a track only, show only, all out race car. Its up to the individual I guess, but I use my a/c all the time.

Honestly, I fail to see how that's possible. (I also have yet to see actual proof from anyone, so there!)
The crank isn't going to see a difference... the thing will still spin the belt at exactly the same rate. You could make it longer or shorter, it will still turn the accessories on it at exactly the same speed.
Now, I could understand if the A/C compressor pulley was introducing a ton of drag on the belt... but it doesn't, when it's off. It freewheels.
If there's any difference, it's microscopic from the loss of the couple of inches of drive belt. But prove me wrong, and I'll mail you a Canadian Beer.

Rich, Thats easy the truck didn't come with it so the system is completely different.
On cars / trucks with ac you can switch from hot to cold air which is what I was getting at. Sorry if I wasn't clear. And around here when you get nailed by those freek summer thunderstorms the last thing you want is to be stuck in a car that only thing coming from the defrosters is more heat!
John and I don't normally agree on things either but it would appear we do here. When off the a.c. pully is totaly free spinning just like the idler pulley you'd have to put in its place. So whats the point? Saving 30 or so pounds why not just leave your spaire tire home when you go to the track thats about all the weight you'll save. Now if its a 1/4
mile only car sure go for it. If it ever sees the streets your going to want it there please
believe me on this as this is my first car with working a.c. and one day you will want it there.
BTW. girls don't like to sit in hot ass cars in the middle of summer sweating to death cause somebody removed the a.c. Wanna lose a girls interest REAL quick? Pick her up for a date in mid july in a car with no a.c. and see how many more dates you have with her.
Semper Fi SAINT. May you rest in peace.
So it would be the switch from the cold or conditioned air to non-conditioned air that would cause problems. OK, I think I got it now.
