This concerns both P5 and P6 but hope P6 NADA owners may know the answer. I have a V8 version of both, the P5B had aircon as per P6B, except for the evaporator, which is Frigiking, installed before delivery to the customer (I have all the original paperwork). When I bought the car the York compressor had been removed but the three belt pullies retained on the crankshaft and standard P6B water pump installed. The rest of the aircon kit was retained. The engine still had the compressor bracket on it and all the removed kit was in a box. So I am able to reinstate the aircon. However, I notice that the fanbelt pully is much smaller in diameter than that on the standard water pump - is that correct?
