Looking to redo the A/C system on three 123.
Will change over to R134. Replace all hose's. Possible have Hose Master make hoses instead of factory. Replace evaporator.
Not sure if I will replace compressor and clutch. Will replace all O Rings with green and replace oil with Ester.
Is there a Special Expansion valve for R134?
Larry Bible please check me out am I missing something?
I know some are all frozen over and don't want to think about A/C just looking ahead.
Thank you.
Charlie
