I did but he hasn't replied. Anyway I'll get the pictures soon but I need some help with air conditioning. I sent the car to the air con shop for a recharge recommended by the mechanic at RNF and the car is installed with a parallel condenser. He said he couldn't do it unless it was the original, his reasoning was that the condenser installed wouldn't cool the refrigerant fast enough and that the pressure was wrong causing the compressor to work too hard. He checked for pressure on a valve under the jump start terminal. I've read on another thread that parallels shouldn't be a problem. Is he right?
I would still instruct the shop to fill the system and try it out. You will doubtless have the same dilemma I have in that my [early] GTS chassis has the earlier design for R12. If this is not available in Brunei you will have to run with R134.
If the drier bottle has run R12 you should replace it and maybe the a/c hoses as I did. The system will run on R134 with modern refridgerant oils capable of lubricating both systems.
If when you run the system the compressor is struggling that is another matter and would need to diagnosed appropriately. These systems are difficult to keep sealed and perhaps more so in hot climates. It is warm and humid in Brunei but not hot by and large.
We have to deal with temps in the region of 45C you see about 32C in your summer I seem to remember.

I suspect the original owner didn't top up his power steering. Before going to the mechanic I looked into the reservoir and there was barely anything in it. I topped it up with dexron III turned the steering wheel, let the atf suck into the system and then top it up according to the dip stick. I added around half a litre but now there's about a fifth left. How much does it take to fill a dry system?
