6. Check the coolant
(a). If a new compressor is replaced, before installation, adjust the coolant in the new
compressor as required.
Coolant volume in new compressor - residual coolant volume in prior compressor =
volume to remove
NOTICE:
• As the coolant remains in the A/C pipe, if no adjustment is performed, the coolant volume
in the system is excessive, which affects the heat exchange rate of the coolant return
pipe and leads to cooling defect.
• If the residual volume is minor in the removed compressor, check for leakage in the A/C
system.
