I have a 1987 379 Peterbilt. I need to recharge the air conditioning and am having trouble identifying the equipment. The parts book lists "Freon Compressor SK16882" B/M number 020-701-A03. Can anyone direct me on the type of freon this compressor requires? Also, where are the charging ports located? I did have it recharged awhile ago, but it needs another boost. Thanks.

Is there a conversion kit? Or an option to upgrade to a newer refrigerant?

I’m sure it’s been converted to 134a. I haven’t seen an R-12 system in years. Easy way to decide is if it has the 134 fittings or R-12. Low side will be on right side firewall in a line. High side is any ones guess as lines are sometimes made from cut to fit hoses at parts stores and could have been moved anywhere to get the guy cool that day. It’s usually in the discharge or smaller of the two lines off the compressor. They are also a different size so no messing it up so to speak
