A/C COMPRESSOR
Removal (3.8L Engine)
1) Disconnect negative battery cable from engine block ground
stud. Discharge A/C system, using approved refrigerant
recovery/recycling equipment. Remove serpentine drive belt. Disconnect
electrical harness connector. Remove strap from compressor and
condenser hose assembly.
2) Raise and support vehicle. Remove compressor and condenser
hose bolt. Disconnect compressor and condenser hose assembly. Discard
"O" ring. Remove compressor bolts. Remove compressor and rear bracket
(if necessary).
Installation
1) To install, reverse removal procedure. If compressor is
being replaced, drain refrigerant oil from old compressor. Measure
amount of oil from old compressor. If measured amount is less than one
ounce, add 2 ounces to new compressor.
2) If more than one ounce is drained from old compressor, add
same amount to new compressor. Clean all fittings with mineral-base
refrigerant oil. Lightly coat all seals with mineral-base refrigerant
oil before assembling. Evacuate and charge A/C system.
