| Post subject: | Rebuilding factory air cond. systems- comments? |
Two upcoming projects- 74 Dart Sport & 75 Swinger, both /6 with remnants of the original factory air cond. systems. During the project I will upgrade to R-135. My plan now is to use the original compressors, interior venting & controls, to cut down the hassle of building custom installations. Local shops are quoting $600 - $1200 to convert- using the stock compressor and evaporator if possible. That's a sizable chunk of money for a DIY project. On the web I found no kits specific to the mid 70's A-bodies, but many offered to help work out the details. All seemed "iffy" of their applicability to my cars, and not cheap either. Then I'd still have to take it to a shop to get the system oiled & charged. Any thoughts? |

You will need new O rings and hoses. The original lines are too porous to contain the new refrigerant molecules. You will also need new compressor lubricant. I hope CharlieS comes along. He is a AC tech and a genius when it comes to this stuff. He can tell you exactly what you need. |

You mean R134a. If the existing compressor and evaporator are in good shape, there's no reason not to reuse them. You'll want a new parallel-flow condenser; it won't be expensive. See here (and threads linked there) and here. |

Oops, R-134a. Thanks for pointing out the old discussions Dan. |
