INSPECTION
MAGNET CLUTCH

Inspect clutch plate and clutch pulley for signs of oil.

Check clutch pulley bearings for noise and grease leakage.

Using and ohmmeter, measure resistance of clutch coil between
clutch coil lead wire (1) and compressor body.
If measured resistance is not within tolerance, replace coil.
Standard resistance: 2.5 ± 4.5
at 20C, 68F
COMPRESSOR THERMAL SWITCH
Use an ohmmeter to check thermal switch for continuity. If there is
no continuity, replace it.

FLOW CONTROL VALVE
As the discharge rate of the P/S pump increases in proportion to the
pump revolution speed, a flow control valve is added to control it so
that the optimum amount of fluid for steering operation is supplied
according to the engine speed (driving condition).
Described below is its operation at different engine speed.

HYDRAULIC PRESSURE IN P / S CIRCUIT
HYDRAULIC PRESSURE CHECK
1) After cleaning joint of high pressure hose and P / S pump thor-
oughly, disconnect hose from pump and install special tool (oil
pressure gauge, attachment and hose).
Tighten each flare nut to specified torque.
CAUTION:
Take care not to cause damage to A / C condenser during
service operation, if equipped.
Special Tool
(A): 09915-77410 (Oil pressure gauge)
(B): 09915-77420
2) Check each connection for fluid leakage and bleed air.
Refer to ªAIR BLEEDING PROCEDUREº in this section.
3) With engine idling, turn steering wheel and warm up engine till
temperature of fluid in P/S fluid reservoir rises to 50 ± 60
C (122
± 140
F).
4) Check back pressure by measuring hydraulic pressure with en-
gine idling and hands off steering wheel.
Back pressure: Lower than 1000 kPa (10 kg / cm
2, 142 psi)
When back pressure is higher than specified values, check con-
trol valve and piping for clogging.

5) Check relief pressure

Increase engine speed to about 1,500 r / min (rpm). Close
gauge valve gradually while watching pressure increase indi-
cated by gauge and take reading of relief pressure (maximum
hydraulic pressure).
Relief pressure:
6200 ± 7000 kPa
(62 ± 70 kg / cm
2, 882 ± 995 psi) G16 Type engine. . . . . . .

7050 ± 7850 kPa
(70.5 ± 78.5 kg / cm
2, 1003 ± 1116 psi) H25 Type engine. .

When it is higher than specified values, possible cause is mal-
function of relief valve.

When it is lower than specified values, possible cause is either
failure of P / S pump or settling of relief valve spring.
CAUTION:
Be sure not to close gauge valve for longer than 10 se-
conds.

Next, open gauge valve fully and increase engine speed to
about 1,500 r / min (rpm). Then turn steering wheel to the left
or right fully and take reading of relief pressure.

When it is higher than specified values, possible cause is mal-
function of relief valve.

When it is lower than specified values, possible cause is failure
in steering gear box. Replace gear box.
CAUTION:
Be sure not to hold steering wheel at fully turned posi-
tion for longer than 10 seconds.
BOOT
STEERING RACK BOOT CHECK
Check boot for crack and damage which, if any, means possibility
of rusty gear, entry of dust or lack of grease. Also, check if any of
such faulty conditions exists.
Check steering rack boot for dent or breakage.
If there is a dent, keep boot in most compressed state for some se-
conds to correct dent.
