110 aircon using a Disco 3.9 compressor. Issues

[coops71]

A year or so ago I put my serpentine 3.9 into my 1988 110. The 3.9 serpentine compressor has different hose fittings and service valves to the original compressor. Both are CFC free versions and the evaporator and fan box and compressor are in good condition. Reciever/dryer has been exposed a bit to the elements so may need to change.Im after ideas on getting new hoses/fittings and an idea of cost. Cheers

Just find a decent car a/c place that can make hoses/fittings up to suit.

A dryer is cactus if left open to the elements for only a couple of minutes ;)

If the compressor has been left open, at a minimum it will need a flush and re-charge with fresh oil, and the new oil needs to go in immediately before hooking everything back up and the system is pressure tested and evacuated.

The reason for this is that the PAG oil used is unbelievably hygroscopic and pulls whatever moisture is in the air straight into the oil.
This in turn reacts with the oil and refrigerant under heat, creating several acids.
