Which side is the low pressure valve located on the 86 Monte Carlo SS V8 duracool A/C system?
The low pressure side of the system can be accessed through a 1\4 port located on the accumulator(a large cannister usually near the firewall) or on the large line.


The small line is the high pressure side and should only be serviced by a qualified repair facility
