Tom-

the changing of a compressor to the Sanden, is something I would recommend people should do. If your A6 is fine, no sense in changing, but there are benefits to the sanden. Yes it is less BTU's, but it has plenty enough unless you are adding large multiple evaporators. It does not seem to load the engine like the A-6. I cannot ever tell when the compressor clutch kicks in or out, is running or not running. the bracket and compressor also allow for removal of the valve cover easily if ever needed too. Pretty clean looking.


the conversion is always more complicated then some make it sound, but it is not anymore complicated then probably anything else you can do.

you need the compressor itself, and it uses a different bracket. the compressor comes with a 2 grove V belt pully, and you need a different belt for it. you will not need 2 belts, one of the two grooves lines up properly.
(napa XL-7585 is the one I am using). if you have a horse collar type fan shroud, you will have to do some cutting/notching of the upper shroud bracket so the belt does not rub.

the hose fittings to the compressor are completely different, then what the A-6 uses. so you either need new hoses made, or if your hoses are in good shape, you maybe able to cut of the old fitting and crimp on a new one.(I have not done or tried this). Jim K's kit I think comes with the needed hoses. You also have to cut and wire up the wire that engages the clutch, as that connector is different between the compressors.

If yours is converted to r-134, you should be fine on refrigerants as long as you don't install another compressor with the old oil in it. as I understand the oil is what you don't want to mix.


I installed the new compressor/bracket/belt, made my own hoses and have them up to a vintage air under dash aux. evaporator, bypassing and not even using the original dash air evaporator. I replaced the dryer, and I used a aerosol "flush" can and compressed air to blast everything out of the condensor(the only part that I retained from the OEM system). so I am running PAG oil now with duracool refrigerant.
