Was there ever Series 1 Air Con available?

Interested in doing a retrofit if possible
But who does / did a kit? Just evaluating at the mo

I had a Series III that had some dubious maintenance in its history, and had what I believe was the air-con compressor from a Series 1. Nasty big thing, very tall, bolted to a huge steel plate to the LHS of the engine (yes, handy for heat exchange with the exhaust pipes!). Looked like it belonged on an HGV; never worked for me; a conventional crank-driven compressor, rather than the later swash-plate driven compressors.

Early series 1s had an aircon compressor by York (the dirty great big one Paul mentioned). Later cars adopted the Frigidaire (later known as the GM Harrison) unit and that one (7L 42595 onwards) was used on series 1, 2 and 3 cars. Mike.

Thanks for the replies. On the hunt for a Fridgidare system then
Might there be something in the scrappys?

Not that so many are being scrapped nowadays...

One thing to remember is that the original systems used R12 gas which is now illegal and no longer available. It was absolutely brilliant as a refrigerant. Shame it was also brilliant at making holes in the earth's ozone layer! Currently available gases, like R134a or other replacement gases will work in the old systems but they are much less effective. Hence, before you go to a lot of trouble to install an original looking system, it might be worth considering ditching originality and checking out a modern upgrade kit which utilises modern components more suited to R134a or even devising your own kit.

I second Mike's suggestion. I'm looking at sometime fixing the air con on my '91 XJS, and will probably get a more modern compressor than the Sanden original. Given so many modern cars have air con, the prices ought to have come down.

Also, don't forget that air con is a lot more than just a compressor. (Sorry, I somewhat diverted the discussion by replying about the compressor so early in the thread.) Certainly by my Series III, the full-blown climate control was a wonder to behold, with a plethora of servos, sensors and vacuum-operated flaps. And a heck of a lot of wires. If the Series 1 was similar, I guess the best way to get retro-fit would be the get the entire dash and air-con unit second hand; and there'd still be other ancillaries under the bonnet, and possible leaking hoses and blocked expansion gizmo.

Perhaps, if such a thing exists, a modern after-market fitment would be easier, better possibly cheaper.

If you're on the OEM trail it's possible. But:
previous systems' lubricant oil is NOT compatible with R134a systems that use PAG oil.
Hoses need to be changed for "Barrier style".
"O" rings too as R134a is more leakable than R12
R134a is more inefficient a coolant so an up-rated condenser of the "manifold" or "parallel flow" type is needed
A better alternative to R134a is R406 that doesn't need the lubricant to be evacuated. But does still need the hoses and "O" rings changed out

If you don't care too much about only having OEM components then I've come across this kit of sorts:
This one requires addition of compressor and condensing radiator with fan.
They offer two styles of each. Their catalogue is p253 - 255 followed by some install notes

Could be the answer for this excellent weather -- the fan box facia can be changed to give four outlets for routing into
existing dash hoses

An interesting site that could be useful for lots of us. Thanks. Mike.
