air-conditioning retro fit -series II

[HJMiller]

Has anyone and information on retro fitting air-conditioning to a series II saloon?

Originality is not necessarily an issue, but how practical/cost effective/possible is it?

Thanks

My series 2 was specced with aircon from new. With the old R12 gas (now illegal), it worked well but over the years, I've had to replace the compressor several times. Converting it to R134a along with yet another new (original style) compressor destroyed its efficiency (nothing like as cold as it used to be) and I wish I'd considered updating the aircon components and gone for one of the kits available. FWIW I notice there's an ad in this month's magazine (page 73) for one of these kits. Mike.

Given the recent summer and predictions for a similar autumn thought I'd post my aircon notes
(to tempt fate )

Air Con Notes
~~~~~~~~~~~~~~
Previous systems up to Oct '00MY used R12 or Freon as a refrigerant.
Later systems used R134a.
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 nore inefficient a coolant so an uprated 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

Kits: two known brand names are Diavia or Eberspacher

If installing a second-hand system, get a new "dryer".

I have been looking into this at great length with my XJC restoration.

It has been recommended to me that the system from a series 3 will work, however, there is a great deal of work involved in the entire process.

The blowers, wiring, heater box, various switches, pipework need to be removed (and labeled) very carefully.

The crank pulley also needs to be changed along with the bracket for the compressor.

With the engine out its an easier option, but still enormously time consuming.

But it can be done - so I'm told.
