Retrofitting of A/C to a 164
Hi as I'm sure you guys are well aware this topic has been well covered with respect to 240s (Dave Bartons write up was excellent as well as a few others on TB) however I feel im in deep water when it has come to fitting entirely new parts to a 164. I have a couple questions that hopefully someone may be able to assist with.
- what size fitting do the late 240 evaporators take (ie the aluminium one for r134a) I know the the big line is a 32mm nut but not sure what this is in ac terms and also the smaller line coming out.
- also using a sanden style sd508 (supposed to be for a Jeep Wrangler) which I believe is the same as a 240 compressor. does anyone know the fitting sizes for these.
-where would I mount an orifice tube(is there a way to know which type is suited to my setup) and where to mount a high pressure cut out (the low is already in the 240 gm style drier receiver)
- I assume that wiring the cut off switches just involves wiring them to the compressor so that they will cycle it on or off due to varying pressure
- will an A/C shop be able to work out the required amount either freon or HC required given the system doesnt have a known capacity since the parts are essentially universal...
as its starting to get hot down under im very eager to get this all together. this is essentially the last step.
I hope to recharge with a hc refrigerant as from what ive read it is much more efficient and despite going for a parallel flow condenser I could only fit a 21x12 inch one due to restricted space on the 164 facia.
to answer a question from my last post I have taken the advice that I was given and gone to a hydraulic shop rather than an a/c shop and they were much more willing to help so looks like it may be a good option. I can get a quote once I find out the fittings I need.
Cheers!
