CFC-Free A/C Retrofit Kit for Pre-1993 Volvos

Introduction; Kit Contents: Page 1

Years ahead of legislation, Volvo first introduced CFC-free air conditioning on all of its U.S. and Canadian 1993 model cars.

With the public's increasing concern about the environment, Volvo released a retrofit kit for older model Volvos in the spring of 1993. The kit allowed Volvos with existing R12 freon based air conditioning systems to be converted to use a CFC-free refrigerant. Volvo was the first automobile manufacturer in the world to offer such a conversion kit for older model cars.

When I purchased my kit from my local dealer, I was shocked to find that it did not include any type of instructions. They were kind enough to fax it to me. This is a web version of the instructions that I received. I have added some of my own comments in italics. This is not a job for the weekend mechanic. It does require special tools. Some of those tools can be used at the shop then the work done at the house.

[Editor] When the instructions mention "torque joint to 12 Nm" this means to tighten until snug. Don't overtighten: the seal is made by the o-ring, not the threads. Lubricate the o-ring before installation with compressor oil; use a backup wrench on all fittings; and test with soap solution (which will bubble in the presence of a leak) after
