Following a loss in the AC cooling effect on my 1991 2.3 9000SE, I noticed that there was a film of oil along the surface of the hose from the compressor to the condensor. On close inspection there appears to be tiny pin pricks, perhaps machine marks in a straight line about every 25mm along the length of the hose and the oil (and no doubt gas) is coming from 3 or 4 of these. Any ideas? are they perhaps the manufacturers early warning system of failure? I expect I will be able to replace the hose, but what about the gas; do I have to retro-fit or is it still possible to top up with R12?

Thanks.

Cordial greetings and welcome!

It is illegal for anyone to sell/supply R12 anymore. There are now, however, replacements for both the gas and the lubricant which allow the original hoses and seals to be used.

I suggest you ask around or look in the phone book for your local A/C specialist. They should be able to spot the leak, and if not they can put in a flourescent dye, and see the leak under UV light. And once you've replaced the offending part they can recharge and you'll be ready for the summer.

Harry,
I had a diagnosed hose leak on mine. I checked the price of the hose with a Saab dealer.
It was £224 inc vat.
I calculated that the whole job to fix and convert to R134a would be about £600.
I turned my ac off. ?
On my car,a 1991 made '92 model, the two hoses to/from the commpressor are in fact one part. If the two hoses end in a rectangular 'block' which has one bolt securing it to the compressor then it's like mine.

Thanks for your replies. I know Saab prices are outrageous! I went to a local firm that fixes and makes up JCB hydraulic hoses and the like, when the pipe corroded on the hose from the automatic gearbox to the cooler (thoughtfully incorporated into the water radiator by Saab). It only cost me £20.00 and they reused the old connections to ensure a fit. However, the gas is the problem. I think I shall have it all taken out and once fixed, see if it can be refilled using something other than R12 as suggested by Mark B. without having to renew the seals etc.

You could well find there's no gas left in it anyway !

I had new a/c rad, thermo cooling switch and three refills of the new gas with added lubricants, all in cost iro £250.

Had seriously considered leaving it off but when its working - its just too good.
