Hi Greg,
got the identical system in my Trakka . It did not function when I bought the vehivle 8month ago. I took the Sanden out (srew fittings on top) and loosened the compressor.
next I disliked (to put it mildly) the agricultural fitting and bought the proper one from BenT. Once it was all clean ,looking like new, it was installed. Btw the wiring to the distributor
was routed under the steel bracket and the wiring was severed , the fitting at the distributor was torn out due to stress and all would have failed within the next few hours of service.
The compressor fits the bracket of course, in a much better, simpler way. After connecting the hoses , and after an oil change of the compressor, I flushed the system followed by
drawing a vacuum for 8 hrs. .Then leaving the vacuum for 24 hrs to check for leaks, R12 was used to charge the system. I use no scales or quantity equipment for charging.
I use a frigies experience and common sense when the right amount of refrigerant has entered the system. (backpressure and temp of returning gas at compressor inlet).
In my years of commercial refigeration I maybe replaced a handful of expension (TX) valves. Most of them , because they were the wrong ones in the first place. The same stands
for the filter/drier, change it by all means it's cheap enough and easy to get to. Although my compressor is noisy it works a treat, of course not cooling the whole car, but giving me a
cool breeze into the face.
Greg, aircon is dead simple once the basic rules of physics are followed, however they are no longer taught and when you talk to your towns eggsperts and show them this letter they
will tell you that I'm nuts and should be questioned for using R12.. Good luck ,Hartmut (formerly FREEZE 22 Commercial Refrigeration Services , Krugersdorp RSA )

Subject: [Syncro_T3_Australia] A/C help
Hello, My prestige A/C system in my Takka has just died. (its never been brilliant) Its been holding a charge but the compressor is shot. From reading the many posts on this subject I would just like to check a few things before proceeding.
The compressor I need is a Sanden SD7 H15????
Can someone give me a manufacturers name and number for a TX valve replacement that works on these systems.
Should I fit a genuine compressor bracket at this point and will the new Sanden Compressor fit the genuine bracket without requiring any alteration?
With a new compressor and TX valve will the bloody thing cool down the inside of my vehicle? The old one didnt.
and lastly
Should I know anything else before seeking advice from the experts.
Thanks for any information it is appreciated. Greg
