I bought a kitcar a few years ago; it has a 302 Ford engine and came with an aftermarket AC which worked fine until recently because I rarely start up the car. The kitcar was put together around 1989, and I am pretty sure the AC system was installed at the time that the car was built.
I don't know if it is Freon or R13 (or whatever the newer gas is called). I happen to have a few old cannisters of freon so I could put that in, but am afraid that it might damage the compressor if it is supposed to be loaded with R13 instead.
Here are my questions to someone out there who can help me:
If it is engineered for R13 and I put in freon, will it cause damages? Conversely, if it is engineered for Freon and I put in R13, will it cause damages? Lastly, if each will hurt the other, how do I determine which gas to use?
There are no identifying manufacturer's stamps or logos or anything else to identify what company manufactured or installed any of the AC system parts. The only manufacturer's name on the entire system is "Viking, Corry PA" which is stamped on the plastic caps on the D and S valves which are part of the compressor. Wasn't 1989 around the time that the switch was made from freon to the newer gas? By the way, I would attach the gas line to the "S" valve to put in new gas, correct?
Please help me.
