86 coupe a/c

[L DC]

Hi Tony;

Could you please elaborate more on the "mini york" A/C compressor substitue. Part #, price range, availability and any other info you could provide.

Would you happen to know if the "mini york" compressor is plug-n-recharge with new freon or does it require a custom bracket, ect.

I'm kind of in the same boat as Mark.

I own an '87 VW Quantum Syncro, which share same engine/drive train as in the Audi 4KQ and, thus, also share the same A/C piston-driven york compressor and like A/C parts also as in the Audi Coupe 5 cylinder can.

Anyway, last summer I charged the system for the second time and worked fine for about 1 month. Same thing happened the summer before that.

I know the system has a leak somewhere and just before it started to blow semi- cold air, the compressor began to make little noise and the clutch would stop spinning. If I hit or tapped the clutch with a stick or something it would engage but with noticeable noise until the point that no tapping would engage it anymore.

I am planning on having all the hoses rebuilt as well as replacing the reciever/drier with a new one and if I can replace the compressor with a good substitue, that would be even better.

Thanks in advance.

BTW, temperatures here in South FL have been reaching 97*F, not including the humidity factor!!
