4. LEAK TEST — HIGH-PRESSURE SIDE
Operate the A/C system for approx. 10 minutes, then turn
the engine off and begin the leak test.
1) Begin at the connection of the high-pressure tube to the
evaporator, and work your way along the high- pressure
side of the system to the compressor. There are three
places to check on each tube connection.
2) Check the area.
(1) Check the area where the fitting joins the tube.
G4M0613
(2) Check the area where the two parts of the fitting
join each other.
G4M0614
(3) Check the area where the nut joins the tube.
3) Check the area of the sight glass and pressure switch
(dual switch), and also check the seams of the receiver
drier.
4) Check the connections of the tubes to the condenser,
and also check any welded joints on the condenser.
CAUTION:
An oily area on the fins of the condenser may indicate
a leak.
5) Check the area where the hoses attach to the compres-
sor.
6) Check around the machined portions of the compressor
(where the compressor sections join each other).
7) If equipped, check the thermal limiter on the compres-
sor housing.
8) Check the compressor shaft seal by probing near the
center of the compressor clutch pulley.
NOTE:
Some shaft seals have a very slight amount of normal
leakage [approximately 28 g (1.0 oz) per year].

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.
