Greeting,
On my 1983 240's compressor there are two identical valves side by side
on the front of the compressor. Both have pressure in them (tested). The
receiver/accumulator drier has that small round window (I cannot see anything in the window),
next to this window is the word "IN". I have access to R-12 and a
shop here in town is willing to vacuum my A/C system and put the R-12 in. I just
want to make sure they know what they are doing. Does anyone know which of these
vales is which? And what should I be looking for in the small round window.
Any and All Advice is appreciated.
Thanks
Joseph in HOT New Mexico.
