just a bit of friendly advice: DO NOT, i repeat, DO NOT change it over to the newer R134a if you can possibly avoid it. IF you can get original R12 put back into the system, it is worlds better than R134a. i had the conversion done on my 93 pickup and the cooling with R134a is greatly diminished. about 30% less cooling ability and won't even cool unless driving at highway speed. i know something is wrong, but every mechanic says the R134a does not cool as good as the R12 freon. i wish i would have never converted it now. and living in a hot humid climate there is a lot of difference in comfort.
