Default Refrigerant Charge

Does anyone know the correct R12 charge for my 82'. I have converted it to 134a and want to weigh it in.

On my '71 I have found that 70% of the R12 charge works the best when using R134a. The proper R12 amount should be on a sticker in the engine compartment. Let me know if you don't have the sticker and I'll see if it's in any of my books.

OK, this doesn't answer your question but, did anyone see the "Crank & Chrome" TNN show two weeks ago? They talked about some product that was a substitute for either R12 or R134 :confused: I went to the products section of their Web site, but couldn't find what they were talking about. Anyone?

Please do not add refrigerant to your system without the proper gauges and a full understanding of the pressures involved. I would advise anyone wanting to service their own aircon to go here http://www.aircondition.com/ and read through the entire site. It's very easy to overpressurize and blow up your compressor. No fun. :cry

:cheers:

I think this is what you want.

I put a similar brand that I got from the local appliance store. I wasn't impressed and took it out and replaced it with 134A I think I need to rebuild my heater/air box.

May have been talking about "Freeze 12." I've used it... with ok results.

Dave, Thanks, now I've got something to search for.

This stuff is supposed to be sold over the counter in small cans (I guess at a reasonable price).

If I ever do repair or get a new AC hose, I'm going to have to fill the system with something and this sounded interesting.

Charge to 75% R12 capacity and make sure you purge the system beforehand. I don’t know about your state, but you have to have a license to buy any refrigerant in Texas now. If I remember right I paid around 17 bucks a pound for Freeze 12.

I would strongly suggest using gauges to charge the system to the correct pressure,& make sure that the gas is installed in the low pressure side not the high.
Just wacking cans of gas in until you think you have it right is not a good idea.

Guys, I appreciate all the info on diferent replacements for refrigerants. I work as a factory service tech for a large a/c maker (Trane) and have a universal EPA refrigerant certificate. My 82' does have the sticker with the correct charge, but it cant be read. Anyone who knows the exact charge please email it to me.
