I am looking to remove the A/C in my '71 240Z as I live in WA and just don't need it. What all is involved in this process? DO I need to take it to a certified A/C shop? Will I have to mess with any of the heating system to remove it? Anybody done it? If so, can you give me a brief explanation of steps to take and any pitfalls I may run into?

Thanks again for any help, you guys are awesome!!

You should take it to an AC shop to have any residual freon removed, then you can take it out. In most cases you will not mess with the heater for more than removing the capilary line that runs from the AC control to the evaporator core(it looks like a thick wire, and is usually just stuck in the fins of the core.), and the wiring for turning on the compressor.

You will need to cover the holes in the firewall that will be open when you take out the freon lines. Everything else is usually pretty easy to follow.

But the Ain the 240Z was at best a dealer installed option, and at worst a home brew concoction-you may have a mess, or you may have the situationI just typed about...

You'll also have to make some type of patch to cover the hole in the blower box where the evaporator housing connects to it.

Astrohog, Why do you want to remove it? Why bother to remove this stuff?

My suggustion is let it there and simply don't bother to remove and plug holes.

Just my opinion.

Richard,

The reason I want to remove it is because it weighs more than a boat anchor, it really takes up alot of space under the hood, and here in WA state I really don't see a need to have a (marginal anyway) A/C in my part-time driver.

I tried to put the stock air filter box back on this weekend and it wouldn't fit with the A/C in there. Am I missing something? Anybody else have this issue?

Is your AC a York mounted on the drivers side? The front of my air cleaner has been smashed on the bottom of the front air intake. It barely clears the compressor. I think that over time, or the PO/dealer did this to make some clearance. By looking at the fit, it would have been darrn near impossible to fit without having to alter the bottom of the compressor.

Randy,

To be honest I have not looked at the A/C that close, but it is mounted on the drivers side and I would have to smash the front air intake to get the stock airbox on!

Jeff

I understand. My compressor is a rotary type instead of piston as the York model and is located under the air pump. It is barely visible and not a nuisance at all.

I don't know if I am correct but it seems that your type of compressor was more commonly mounted on the passenger side close to the fuel pump.

Astrohog, you must have the same A/C as jmark. (There's a picture of his in the second link.)

What I plan on doing to rectify this problem is cutting out the offending section on the bottom of the air cleaner with a die grinder. That will allow the use of the original air cleaner without having to buy aftermarket air cleaners and having to deal with the plumbing issues that arise with the use of them.

Of course, you could always purchase a rotary style air compressor which is smaller than the old York AC. Stephen would be able to point you to the pros and cons of this approach. It has been discussed numerous times in the forums.

I have the same setup as jmark's if you look at the link Arne posted above.

If it wasn't "marginal" I'd take the A/C off your hands because it would come in handy in Eastern Washington. Maybe when things are done I'll invest in one of those pricey new MSA units.

That would depend on which 'dealer installed' system it is. They're not all marginal especially the ones that don't use York compressors. I have achieved acceptable results with the Sanden/Sankyo rotary compressor systems. Basically, all you need is the biggest condenser that will fit and a better fan and proper sealing between the vents, ducts, etc.
