11. Compressor
Compressor is a swash plate type. When trouble occurs,
replace compressor as a single unit.
B4M0090
A: COMPRESSOR CLUTCH INSPECTION
Compressor clutch trouble is often caused by clutch slip-
page and noise. Check and take corrective measures, as
required.
1) Remove belt cover.
2) Check that clearance between drive plate and pulley
over the entire perimeter is within specifications.
Clearance:
0.3 — 0.6 mm (0.012 — 0.024 in)
B4M0091
3) Check that voltage applied to magnetic coil is at least
10.5 volts.
4) When noise is noted, check that it originates in either
compressor or pulley bearing.

B: REMOVAL
1) Disconnect ground cable from battery.
2) Discharge refrigerant using refrigerant recovery system.

(1) Fully close low-pressure valve of manifold gauge.
(2) Connect low-pressure charging hose of manifold
gauge to low-pressure service valve.
(3) Open low-pressure manifold gauge valve slightly,
and slowly discharge refrigerant from system.
CAUTION:
Do not allow refrigerant to rush out. Otherwise, com-
pressor oil will be discharged along with refrigerant.
