Caution
The operations described below are based
on bench overhaul with the compressor
removed from the vehicle, except as noted.
They have been prepared in order of
accessibility of the components. When a
compressor is removed from the vehicle for
servicing, the amount of PAG lubricant
remaining in the compressor should be
drained, measured and recorded. This PAG
lubricant should then be discarded and an
equal amount of new PAG lubricant added to
the compressor.
The service compressor is shipped without
PAG oil. When service procedures require,
use only Isuzu approved PAG oil.

CAUTION
When fasteners are removed, always
reinstall them at the same location from
which they were removed. If a fastener
needs to be replaced, use the correct part
number fastener for that application. If the
correct part number fastener is not available,
a fastener of equal size and strength (or
stronger) may be used. Fasteners that are not reused, and those
requiring thread locking compound, will be
called out. The correct torque values must
be used when installing fasteners that
require it. If the above conditions are not
followed, parts or system damage could
result.
