I am tossing around the idea of converting to a V5 compressor in favor of the R4 that is in place.
Also was thinking about putting an expansion valve in instead of the orifice tube - just to get that extra cold out of the system.
I will have to get new hoses made for attaching to the compressor... the suction and discharge ports are flipped around between the two units.
I intend on putting new O-rings and seals in the V5, just to eliminate having to do it later. While I got the unit apart, would putting in a new control valve be a good or bad idea? I would like to use R134a.
The questions I have are.. Anyone got a part number for a connector block to use on the back of the compressor? O-ring fittings will work, as it's on a truck with lots of room.
Would it help or hinder to fab up an expansion valve with this compressor? Will the two variables fight against each other ( the compressor and the valve ) would I just be better off with the condenser mounted orifice tube.
Love this site, lots of information here. Thanks a bunch
Been done before, works well.
I would go with the V7, displacement is always good. 4 ear mount V7
The variable displacement compressor is great with a TXV. They work together, just like the TXV+POA systems did. With a V7's displacement & a TXV you are building the functional equal of an A6 / TXV / POA system.
There is a fitting block available to mate the back of the GM compressor to standard O ring hose fittings. Tim will know the P/N.
