NOTE: Installation of a new suction accumulator is not required when repairing the air conditioning system except when there is physical evidence of system contamination from a failed A/C compressor or damage to the suction accumulator.

The front condenser to evaporator tube contains high pressure liquid refrigerant. It has the following features:

• a fitting used to mount the A/C pressure cutoff switch. A long-travel Schrader-type valve stem core is installed in the fitting so that the A/C pressure cutoff switch can be removed without discharging the A/C system.
• a fitting used to mount a repairable high-pressure A/C charge port valve.

The rear condenser to evaporator tube contains the A/C evaporator core orifice. When the A/C system is in operation:

• there is high pressure liquid refrigerant upstream of the A/C evaporator core orifice.
• there is low pressure liquid refrigerant downstream of the A/C evaporator core orifice.
