My mom's subie will work a bit then stop.
So I was at WAL Fart and saw a conversion kit for 34 bucks, 3 cans with oil mixed in and gauge, so I got it.
The adapter screwed into the low pressure side, (can screw on to high pressure side as well), and had a sealant on the threads.
Low pressure side is NOT the side that comes off the condenser.
At least this is what I've came to understand.
My zx has 86k on it and was stored properly before I got it.
The O rings on the compressor were in fantastic shape so I did not want to break a bunch of seals that may be fine. I did lightly grease the o rings before reinstalling compressor. (ya know help to fight micro abrasions).
Installed a 16in fan on condenser and wired it to a switch by the stereo, then reasoned that there is a switch in the atmosphere controls that engages the clutch, so I took that apart, found the switch, followed the wires past the plug and intercepted them and put them on a switch next to the fan switch.
Main reason for this is that I did not want anyone activating the system without the condenser fan running!
Added benefit I CAN RUN ALL THE DIFFERENT OPTIONS ON MY ATMOSPHERE CONTROLS!!!
This is nice for the winter running the defrost and heat at the same time with the a/c!
Had to use that yesterday, worked fantabluless!
So only hitch so far, after second can of 134a the gauge was on the line of blue to green and the system was blowing cold air.
After the third can the result was the same......
Did not want to get another, and, did not want to overcharge the system, so I left it.
Ran the car hard Sunday seems to be working nicely. The big test is when it gets into the 90s. Seems like the system dose not take a "break" like the newer systems.
Especially getting on it, the system will blow VERY cold, otherwise works better then I suspected.
I will post up some pics later.
I put on a econo belt for now because I did not want to get a gator if the system was not going to work.
Now the system "blew" due to a lack of a condenser fan, (mech fan long gone for engine), the guy a smucks told me the is not a pressure release valve.
He seems to be wrong due to the system holding pressure form the get go.
My guess is that it is at the collector (accumulator?).
If I have a small leak, time will tell, them I will have to take it in, possibly, due how slow it is. I guess I could use some soapy water. Will see.
One last thing, I did not use teflon tape, or my favorite, pipe dope, due to the fact these are not tappered sealing threads. The o rings are the seal.
