  Q: How to replace the A/C Accumulator in an A/C system on Chevrolet Metro?

  A: The first step to replace the A/C accumulator involves recovering and discharging the refrigerant. First remove inlet fitting along with bolt from the A/C accumulator top before taking out outlet fitting and bolt from the same location. The following action requires you to unscrew the A/C accumulator retaining screw on the bracket before removing the A/C accumulator from its position in the bracket. New A/C accumulators require 10 ml (0.3 fl oz) refrigerant oil for installation into the A/C system. New O-ring surfaces should receive mineral base 525 viscosity refrigerant oil before they are inserted into the A/C accumulator's inlet and outlet ports. Use the screw to fix the A/C accumulator bracket to the condenser while the inlet fitting needs its own bolt for installation at the A/C accumulator top. Use the same procedure to secure the outlet fitting by tightening both bolts to 9.8 N.m (86.74 lb in). The final step includes evacuated air conditioning system charging followed by operational testing to identify any refrigerant leakage.
