General Repair Notes Regarding the Replacement of the A/C Compressor
^
When replacing the A/C compressor (due to seizure), the low and high pressure lines at the A/C compressor along with the A/C expansion valve must
be replaced as well, thereby preventing any subsequent damage to the A/C system.
Note:
Repeat failures may result in warranty claim debits after warranty parts testing.
^
Check condition of the compressor poly-V-belt or V-belt for overall wear and burn spots. Replace belt, if necessary.
^
Replace the A/C receiver-drier whenever any part of the A/C system has been opened for repair.
^
On principle, replace all O-rings and lightly coat them with A/C compressor oil before installing them.
^
Since A/C compressor oil is hygroscopic in nature (absorbs moisture from atmosphere), perform all repairs on the A/C system in a timely manner and
cap all openings.
