Can an original york compressor accept an r134A setup?

It should; provided that you retrofit the high & low side fittings and use the corect volume and viscosity of oil  ------------------

One thing to consider is that in the old AC systems the seals where the lines attach to the compressor were made to leak oil so that the seals wouldn't dry rot. This is why the old AC systems needed to be recharged every 4 years or so, if you kept the car that long. In the new R134 systems the system is completely sealed. This was also to eliminate exhausting the refrigerant into the atmosphere. With the old system CFC's were directly exhausted into the atmosphere with the slow-leak seals. Your old york compressor is not designed to seal completely. I would switch to a Sanden for the weight savings and efficiency gain. Steve ------------------

The higher pressures that 134 operates under would be a problem??

I thought it was run with higher pressures but wasn't sure. Might want to look around the net for some info on that.Steve ------------------

I'm switching mine to R134A also. I completely drained it and bought the retrofit kit. I was told the only other thing I needed to do was replace a couple of the hoses that wouldn't stand up to the higher pressure, which I did, and had all the others tested to make sure they'd hold up. I'll be recharging it later this week.

Someone on this site told me about "Freeze 12" a R12 replacement. I haven't tried it yet, but others have. The refrigerant is relatively expensive, but you don't have to replace any parts. I was also told that your R12 compressor, evaporator, and condenser are too small for R134a, since it is a less efficient refrigerant. (air is 5-10°C warmer) I also heard some here express concern over R12 replacements because they contain propane. ???? Good luck.

What is the difference between freeze 12 and the r12? What are the improvements?

R12 is a chlorofluorohydrocarbon which when released to the atmosphere reacts with the ozone in the upper atmosphere. Thus, depleting the ozone layer that protects the earth from ultra-violet rays from the sun.  Thus, the EPA has banned the use of R12 in new automobiles, and has made it available only to licensed professionals. Freeze 12 is a mixture of hydrocarbons and chemicals and has cooling properties to R12.

You can buy Freeze 12 on Ebay. I believe SOME shops use it, but not many. R12 only lasted until around 1994, so it hasn't come on cars in over 10 years, so not too many shops are going to fool with it (or its replacements) anymore. They will be all about converting your car to the (not as good) R134.------------------

Freeze 12 is supposed to perform as well as R12. I've not heard of it being sold here in the Philippines, Mike, probably because R12 is still readily available.

I guess it's still not a big issue here but I've heard rumors that they are starting to ban them here.

Yeah, the government's already tried to ban it, but you know how things work here! It will disappear in time. It's like when they banned leaded gas. You could still buy it a year later. Now it's finally disappeared except in Batangas.[This message has been edited by Fastback68 (edited 06-16-2006).]

I guess supply is not at risk here.
