has the car been converted to r-134a or are you still using r-12?
Accumulator, is this the silver colored cylinder? It does have a port on the metal line coming from it. I know what the compressor is, and the evaporator also. This is a Celebrity, 4 cyl. 87, using R12. I've done this before,
but never on a Chevy. I just want to be sure.
