Default A/c ?

Hey guys I have a 1991 hardbody and I was wanting to know if the A/c out of a 92 model would work on my truck. I can get everything for 100 bucks. Any help would be greatly appreciated. Thanks again.

yes it will fit. the only different thing will be the compressor if one is a 4 cylinder and one is a 6 cylinder. everything else is the same.

i rebuilt my ac system 2 years ago. take my advice........REPLACE the expansion valve and always use a new AC drier. refer to the How to: Retrofitting A/C thread for pics.

Good advice. Those parts are cheap. Also, flush the lines with some lacquer thinner, and blow them out. At the very least, clean the small hard line that runs from the condenser to the evaporator (firewall). Any dirt in there will clog your new expansion valve.

Believe it of not it's the same size motor and the system still has pressure lol. But yes I planned on doing that alone with a new compressor. Thanks for the help guys now I just hope mine has the electrical hook ups lol.

they all have the wiring for AC. it was cheaper for nissan to make one electrical harness, so all the D21s had the option for AC.

and they actually sell AC line flush. its in a pressurized can with a hose. you use compressed air to blow it out.

No, just remove glove box, then the metal tray behind it. Remove bolt on outside firewall where the lines come through, then 3 nuts on inside of the firewall holding box to firewall.

If you plan on using the same equipment, change all the gaskets (O-rings) and find out what type PAG to use to give the gaskets a little lube when you put everything back together.

One thing to remember about PAG oil, it's extremely easy to ruin it. It's heavily loaded molecule wise and soaks up moisture like a sponge. Use a little in a clear cut off plastic bottle as a lube, but the rest, keep it sealed until you need it, and I would personally run leak dye in it just to be on the safe side.
