Outer Limits 4x4 Board

In a nutshell i stumbled across a spare parts car that appears to still have a complete and functioning( holds gas) air con system. While my car was apart i replaced all the O-rings in my system with the new style in anticipation of getting a new compressor and hoses.

I was hoping to use the spare parts compressor, hoses,etc. and just get it converted to r134a gas but am unsure of whats required. Maybe im just better off buying a new compressor and hoses to suit?

Can any one shed some light, I want to strip out the parts car over the long weekend but wont be able to sort out the aircon for a while yet.

THanks, I hope it makes sense

When I converted my GQ a year or two ago from R12, I just had the hoses replaced (original ones were cracking) and the dryer too. All up was about $280.
They couldn't get the adapter valves onto the back of the compressor or something because it was too close to the engine mount, so they just added the valves to the new hoses.

The original hoses aren't that great for r134a gas, as the new gas has a smaller molecule size so leaks out through the rubber over time.
New hoses are probably cheaper than having a re-gas every few years anyway.

Dont use R134a use an alternative like Hychill instead. Lower charge amount and head pressures but works better.

never heard of it. any more details or do i just google Hychill?

You will need to replace your reciver/dryer, blow all the oil out of the the compressor and replace with the suitable oil for the 134a, install the two new adaptor fittings for charging, and the new TX valve inline. Then its just a matter of vaccuming off to make sure you dont have any leaks (replace all O rings in system) and then fill with gas.

Conversion sould only set you back about 300 bucks all up. Its been a long time since I have done a retro fit to an R12 system so I could be out on price, but its quite straight forward.

Been using it for a while now. Can buy it from bursons in an aerosol size can which is enough to charge most systems. It is compatible with R12 systems. Do a google search for more information.
