Outer Limits 4x4 Board

Your advice please...I have recently fitted a high mount winch to my 77 2 door. To fit it into the grill I had to remove the thermo fan which sucks air into the AC Condensor. Although I live in QLD the Rangie is not a daily driver and the AC has no gas and as its the old gas "may" be quite an exercise to get working properly even if I refitted another condensor fan...

So...

Do i pull the AC and its relevant plumbing and condensor and install and endless air pump. I hardly drive it and to regas is a drama so who thinks endless air is a goer????

Do you mean install a new pump from "endless air" or use you're existing ac pump to pump air.

I would re-plump your existing ac compressor to a tank and use it to pump air.

if you really wanted to use the AC as an AC, just find someone that uses Origin 34M as a drop in refrigerant to replace the R12. It works very, very well. Current recommended list price is $52.96/kg (incl) and I'm guessing most car systems take around 6-750 grams. Add a drier and an hour for labour to replace the drier and evacuate the system. Obviously, if a leak is hard to find it may take longer.

I use 34M in farm tractors and commercial refrigeration instead of R134A to increase efficiency.

Or just do as Walker suggests and probably use some sort of inline oiler for the compressor and an oil seperator on the discharge side.

How does the 34m go in systems altready converted to R34a?

fine. I use it in place of R134A as it has a lower discharge pressure/temperature. It's approximately 90% R134A and it's miscible with mineral, PAG or Polyolester oils.

rig up the origenal a/c pump as a comp on the inlet side fit a pod fillter off a small motor bike and fit a 1/4 line to the service valve and put a bit of comp oil down it when you are running it mine his never failed me and i can pop 35" tires back onto the bead much cheaper then a endless air unit

regass it with lp cheap and cold
