AC Conversion
I have an 89 Coupe with an A/C leak. Will I be required to convert to the new type of freon and is this expensive? Has anyone had any experience with this? :confused:

Hi mlsins, after fixing the leak, you could go with Freeze 12. It is an R-12 replacement and will work with your existing system. I had to recharge my A/C after replacing the compressor. You still should place your system on a vacuum before recharging to eliminate any excess moisture. It works just as good as the original R-12.

Re: AC Conversion (mlsins)
I replaced the compressor on my 88 and changed over to the new stuff. The mistake I made was not changing the expansion valve. It has a tendency to get filled up with junk from the bad compressor. Just make sure you change the drier, the expansion valve, the 'O' rings on the compressor (old r-12 rings will have a problem over time) and then find the conversion chart for how much r-134 to put back in. Also get the R-134 compressor oil and put it in after you change all the old parts.
