Hi, My Mulsanne S 92 is ALMOST ready to go, after 4 years of endless search for the right mechanic, here in Portugal....Now comes the issue of changing the gas on the A/C from R12 to R134.... I have searched the net, and on flying spares I have found a kit which provides 2 ounces of oil and the right plugs....HOWEVER, reading other related material it seems that the "drier" in the A/C system also needs to be replaced?? Can anyone offer a more complete description of what must be done? THANK YOU | ||

Pedro, Yes, the dryer really should be replaced. While driers are all the same for R12 and r134a, in use they get full of system oil and it cannot be cleaned out. I would see if a later RR dryer had the same fittings and get one from a 134a car. An AC shop should be able flush the old oil and put in the new accumulator and vacuum the whole thing down for a reasonable fee. Royce or Ford, ac work is one of those things that's the same car to car. Royce brakes.... Well that's a different matter. | ||
