D-90 A/C removal

My wife and I have a 1997 NAS D-90, which we have a great time with; nothing extreme, just exploring
the mountains around here and getting closer to the great scenery we have nearby.

We've noticed that we only use the A/C about once every 245 months, and we're getting tired of the space it takes up out of the interior. So we're thinking about removing it. Is this a feasible DIY project? is there
any market for the complete system after we've removed it?

opinions? gotchas we should watch out for?

thanks all!

Theres a market all right, lots of folks will pay 1k or so for a working AC.

Removing it is simplicity itself, but you need to have the system discharged first by a technician at a dealer or AC place.

The only thing to really watch for is the fittings, especially the ones that enter the condensor which sits in front of the vehicles radiator. The thing is made of aluminum and the fittings are fragile.

There is also residual pressure left in the system even after its evacuated, so be careful while loosening the first fitting.

The parts of the system are as follows:
Underdash vent assembly
Underdash blower unit
Hoses
Compressor, on top of the motor
Condensor in front of radiator
Little canister under the PS resevoir
Wiring

Disconnect all the lines, finesse them out, and then just remove each piece individually. Too easy.

Problem is you will have to leave the compressor in it to drive the serpintine belt.

That is my understanding. Have not seen this yet, but crazy George confirmed it once.

GRRR! So now I need to get an AC compressor for my 4.0 so that I can get the belt on? I guess I can't just get a shorter belt? Anyone got a junk AC compressor for a 4.0 they want to get rid of cheap?

OK, I think I got this figure out but I am not sure everything is turning the right way. Can anyone confirm with this setup / belt config on a 97 that I have aeverything turning the right way? I know bad pic, but camera has a dead battery so i used a PDA. Thanks!

That is correct. My truck has no AC but still has the compressor. As it was told to me, All 97's left the factory with one and the AC was a dealer option. The port of entry for my truck was Toronto, and it was sold in Vancouver, without AC by the dealer.

PERFACT! Thanks Peter! I'll have to look at rotating the pulley; I may just leave it as everything is going the right way.

Aaron,
I've got AC and never use it, been thinking about taking it out after this topic. I'm pretty uncomfortable taking it out though, but if I rip it out I'll let you know.

I am planning on removing the A/C system from my 95 Defender to add more room to the footwells. Is it safe to remove the compressor and use a shorter surpentine belt? Or should I just leave it in and disconnect the connections?

Thanks for the help!

Greg

If you have a 95 as in your profile, you don't have a serp belt. You can remove the compressor and the belt that drives it.
