Propane does the same as R12. I don't recommend it though(highly volatile). Best to convert to 134R. Last time I converted an R12 system was about 10 years ago. I would tell you how to do it, but I could get in trouble because you have to vent out the R12 first. I don't even know of a shop that has an R12 unit anymore. Good for you, they still have the adapters to go over your ports and the 134R today is compatible with the old systems oil. No need to change the compressor, dryer, and expansion valve.
Will need to retro fit your system for r134 the following link explains about retro fitting your a/c system
R12 to R134A Refrigerant Retrofit
Yes but r12 is not user friendly I would recommend you have a r134a retrofit
SOURCE: Ac and heater work great but go off. Then Ac blows Hot / heater cold air
I got a bigger coat to wear! while I find time to look into it further. I appreciate knowing there is more help available and will try the Primo Asist plan later. thank you louie
SOURCE: AC not blowing cold air at times
poss causes are, sticking low pressure switch, defective Ac compressor clutch closing coil or incorrect clutch driven plate air gap, spec is 0.26 thousands.
SOURCE: 02 acura rsx-s AC stopped
my 2002 rsx type s ac did the exact same thing. got to the point that i started hearing a weird noise like stuff clunking around everytime i turned it on. took it into the dealer and they said the compressor just fell apart inside... i had to buy a new one and it wasnt cheap to replace. problem was, the same equipment also played a part in the heating system too... so they told me.

there is a updated ac relay for that, go to your toyota dealer and buy a new mgt relay its located in the fuse box in the engine bay on the drivers side.
SOURCE: How hard is it to add freon to the AC system? My
It's very easy. You can purchase a kit at wal-mart or your local parts store. It will come with a gauge and a can of freon and oil. The system is setup to prevent you hooking up to the high port valve. A lot of people worry about this. You have 2 valves, one small and one little bigger. You want to start the engine and turn on your a/c. Hook the gauge up and see where the gauge needle goes. It's easy to read and will tell you if the system is low or overcharged. If the system is overcharged before you begin it needs to be checked out by a shop. If you need to add, screw the can onto the adapter, with the gauge still hooked up. Once you have the can on tight, screw the t-handle to pierce the can and hold can in up side down position. Make sure when yo pierce the can you screw the t-handle completely down and slowly turn it back open to let the freon in until the gauge reads full, or whatever the gauge may state. After it's full close the valve off at the t-handle and disconnect from your a/c unit.
IN REAL SHOP THESE 2 ARE CONNECTED TO A TOOL CALLED A MANIFOLD. AND IS USED IN A SAFE MANOR.113 views
