Notes on Automotive Air Conditioning

The air conditioning in my 1989 Lincoln Town Car works fine. A 1990 Volvo 240 that I am frequently called to work with does not have a functioning air conditioner.


The car has not been retrofitted to R-134a. I intend to instead retrofit it to R-406a.


On August 2, 2006, I won eBay auction 230013527869, an R-12/R-134a manifold gauge set. I cannot determine if the included fittings will fit an R-12 system, because I seem to be unable to find the high and low side fittings on this 1990 Volvo 240.
