The old York style compressors lasted for ages. As mentioned in another thread the one on my 85 model failed only recently. 30 years out of a compressor isn't bad.

We used to be an icecream wholesale distributor and one of our small urgent delivery trucks had a ThermoKing unit with an engine mounted York compressor which worked a treat for years and years. When we swapped from the Dodge (F150 size) truck to a small Isuzu the York wouldn't fit on the engine so we swapped to the Sanden type compressors, we would only ever get about 18 months out of a Sanden compressor.

The parts catalogue has the 4.4 and the 3.0 using the same compressor part number. This conflicts with D4 release promos and with my experience in the D4 of hearing the compressor cut in and out. I'll ask my son to check the D4 itself.

The 3.0 D4 does not use the same compressor but it is used on one of the D4's engines.

If it is a Sanden then its likely to be a PXE16 which will be on the LR label with the LR part number but the specific 4-digit model number most likely on a small Sanden label is required to fully identify it.

Pretty sure it is a PXE16 under the bonnet on the otherside of my garage, which means I have the links of where to get the RCV

Easy to find suppliers using Google...

Gentlemen, just dropped the car off at the dealer's service department. Spoke to their chief technician, who told me that according to the LRA technical bulletin, the standard procedure in cases of compressor failure is to replace not the whole unit, but just the valves.
However, he said there had been a number of cases of compressor failure after this procedure, including a recent case where the replacement valves failed after only two months.
So he insisted that a new compressor be brought in for me. Apparently the new ones (pictured) have upgraded and improved valves.

I've also taken a shot of the first page of the technical bulletin which specifies just changing the valves.
Should all be sorted by tomorrow arvo. About a 5 hour job, apparently.
