I know it can't be that hard to take the a.c out but if i had a tutorial that would speed up the process and i wouldnt take so long trying to figure that out. If anyone knows where a tutorial is let me know please. Or else give me adivcise on how its done, and or if it is worth taking it out for performance.

zduford

performance wise not really... youll loose about 5lbs i guess...

But the first thing you wanna do is drain the system. (take it to a mechanic shop.) its really deadly stuff. Or if your brave, and have dont care about the environment. open one of the bleeders. thell be little valve type things on the lines somewhere.....OH YEAH....GET THE HELL OUTTA THERE!!!!

Once thats done, there isnt really an order to follow, You'll have to remove the rad though to take out the AC rad, and the bottle thingy. Pretty easy. Then you can just pull off the AC pump.

Next interior. Not to sure if you would have to remove the dash or not. But if ya jump in the Passenger side, and look under, youll see the blower motor, on the far right, and just in from that you see a black chunk youll want to remove that, and then behind that is the AC core.

thats basically it.....if ya have more q's just ask... i have one with the ac ripped out. and its no biggie to go have a look.

You can get it out without removing the radiator, just takes a little more manuvering.
If you dont plan on saving the stuff you can bend/break the mounting tabs to get it out easier.

You may also need to remove the battery and loosen the battery tray to get the long bolt holding the AC pump in place, out.

Refrigerant is not deadly. There might be 3 lbs. in there. While it is not 'legal' to bleed it off to atmosphere, it seems impractical and costly to take it to a shop to have them 'reclaim' the refrigerant.

In my opinion, I would NOT remove the A/C. It is an important feature - it dehumidifies the air and clears windows even in cool weather.

Iagree with zduford that performance gains are minimal. If you do remove it, just remove the heaviest component, the compressor and mount. Other componenets are rather lightweight. SHould someone decide to re-install the system, it would be much easier.

A/C adds value to an automobile.

Rx7Kidd

now wondering if it does or doesnt work is the huge question, if it doesnt blow cold at all, and you need the space remove it. the A/C system all of it weights more than 5 lbs. its about 15-20 the compressor along with mounts and the condensor.

you get the lines on the passanger side unhooked then undo the compressor, once thats done take the plate off that is infront of the radiator. undo the condensor and the little black thingy, not sure name for it. its up to you how to get the lines through the slots in the structure to pull the condensor out, you could undo them or cut them, cutting is fast and undoing is if you want to keep the parts.

other than that its self explanitory, the performance gains are minimal, just weight loss and maybe some respond speed due to the pully it now does not have to pull. if its perfect compressor and pully spins with no friction then probably no different respond speed.

I would leave it in. We all like to think the cars will be around for a long time to come, and A/C might be needed at some point in the future. Removing it decreases the resale value of the car, and makes it into a hack job. It's harder to reinstall and put back than it is to remove.

As alternative to removing it you could disconnect the compressor belt.

zduford

actually, yeah, the refrigerant in the ac is poisions, its freon, and it is a nerve inhibitor.

Yes, you would not want to turbo charge your bong with it; leave those NA. And the MSDS classifications might paint a scary picture, but it is not that toxic during a normal venting procedure, which was normal practice years ago. Adequate ventilation would be wise.

I have heard of kids snorting that stuff.

Rob Stolz

I see, so all of you say to leave it in.
What about the rats nest, is that worth removing, pros, cons???

Wankelguy

It's only a "hack job" if you do a hack job removing it.

I pulled all the A/C equipment off my '80 and you can't even tell it ever had it. I even replaced the big plastic box under the dash that holds the evaporator with a duct piece from a non A/C car. Does it give a performance advantage? Probably not, although the car is about 30 pounds lighter, and there's no A/C clutch bearing to get noisy or seize up at an inconvenient time. Plus, this is Oregon, there's only about a two-week period in the Summer when A/C would even be useful.
Anyway, I've got a complete A/C unit I'd gladly give away to anyone who would come and get it. It was still charged and working perfectly when I took it out a few years ago.

capt murph

Ya'all keep forgeting about the dehumidification that the AC can do. On a damp rainy day, the AC on WITH HEAT ON can clear foggy windows and make it more comfortable.

Hades12

WHAT!!!!!!!


Don't you have a Honda or something you can drive on rainy days. Keep the 7 in the dry. Don't want to get the 7 near anything that could rust it.

remove the ac, like wankelguy says get the duct fom a non-ac car and the rubber plugs that plug into the firewall. hackjob?? LOL.

on the rats nest i would wait till you can afford an aftermarket carb setup. if you install something nice it will eliminate all the emissions crap worry free + net you 25+ more hp. vac leaks suck.

oh yea, ac is for women.

capt murph

you're just jealous.

And I'm just dreamin of getting mine working !!! It appears the engine on mine was out at one time and as it was being lifted/removed, it crushed the one line on the firewall. No gas pressure in the system.

Rob Stolz

So what are the pros and cons of removing the rats nest, would you suggest i do it, will it give me an extra HP or give me a little better gas milage???

zduford

if anything, it will decrease your gas miliage, and as far as i know any HP improvements that are made, will decrease gas mileage.

rotaryfire

I need a new system. I'll pay for shipping if you are willing to pack it in a box for me.

Rob Stolz

decrease gas milage means more kilometres for less gas or more gass for less kilometers???

Rob Stolz

cause i dont c how i would get worse gas milage with that out, if someone could explain that would be awsome

capt murph

Better gas mileage with the expectation that you have the windows closed at highway speeds - reduced aerodynamic drag.
is that awesome or what

Rob Stolz

will taking out the rats nest give me better or worse gas milage??

Wankelguy

It takes a couple hp to drive the compressor when it's engaged, and the condenser presents an obstruction to airflow through the radiator.

About removing the rat's nest: in theory, you shouldn't really see any power gain from removing the rat's nest BUT that's assuming that everything in the rat's nest is working perfectly to start with (and they're notorious for vacuum leaks).
The main reason for taking it off is just to simplify the system.
All a rotary engine needs is some sort of crankcase vent, and a tank purge line.

I don't believe removing the rat's nest will affect gas mileage.

Decrease mileage means less miles per gallon of fuel.

IIRC, Mythbusters did a test with AC on and windows up, and AC off windows down.
AC sucks more fuel.
Although, some cars windows seem to suck more air,(from sitting in the back).

Of course , in the south you can't just roll down the windows and be cool.

capt murph

OK Wankelguy get with the program!!!

My gut feeling is that if you have to ask that question, you'd better leave it, the rats nest, alone. It is very unlikey that you will gain MPG by removing it. IMO.
A mechanic/shop owner I know , said to me one time ' it's not all hacked up with hoses diconnected and plugged up is it?' referring to my 7. I was proud to say No, it is not all hacked up.

With a little learning, have good hoses, you can make things work like they should.

capt murph

whoa my stupidity or this machine I did not see your rat nest reply wankelguy. How'd that happen..
