Pump Belt
NOTE: When using a new b€li, first adiust the deflection
or t€naion to the values for the new belt, thsn readiust
ths deflection or tension to the values tor the used b€lt
after running sngine for five minutss.

Attach th€ belt tonsion gauge to th6 belt and measure
ths tension of the bslt.

. Power assist with car parked.
Check the reservoir at regular intervals. and add fluid as
necessary.

Raise the reservoir and disconnect the return hose
that goes to the oil cooler.
Connect a hose of suitable diameter to the discon-
nected return hose and put the hose end in a suit-
able container.
CAUTION: Tako caro not to 3pill tho tluid on tho
body and parts. Wipe off the spilled tluid at onqe.
Start the engine. let it run at idle. and turn the steer-
ing wheel from lock-to-lock several times. When
fluid stops running out of the hose, shut off the
engine. Discard the fluid,
Refit the return hose on the reservor.
Fill the reservoir to the uDoer level line.
Start the engine and run it at fast idle, then turn the
steering from lock-to-lock several times to bleed air
f.om the system.
Recheck the fluid level and add some if necessary.
CAUTION: Do not lill the roservoir beyond tho

lnspection and Adjustment
Pump Pressure Check
Check the fluid pressure as follows to determine
whether the trouble is in the pump or gearbox.
NOTE: First check the power steering fluid level and
pump belt tension,

1. Disconnect the outlet hose from the oumo outlet fit-
ting, 8nd install the pump joint adapter on the
pump outlet.
2, Connect the hose joint sdapter to the power steer-
ing pressure gauge, then connect the outlet hose to
the adaotor.
3. Instsll the power steering pressure gauge to the

1.
Start the engine and let it idle.
Turn the stee.ing wheel from lock-to-lock several
times to warm the fluid to operating temperature.
Measure steady-state fluid pressure while idling
with the shut-off valve fully open. lf the pump is in
good condition, the gauge should read less than
1500 kpa (15 kgf/cm,,213 psi).
lf it reads high, check the feed line or valve body
unit (see General Troubleshooting l7-10).
Close the shut-off valve. then close the pressure
control valve gradually until the pressure gauge
needle is stabl6, Read the pressure.
lmmediately open the shut-off valve fully.
CAUTION: Do not keep the shut-ott valvs closod
moro thgn 5 soconds or th9 pump could b6 dam"
agod by over-h6ating,
lf the pump is in good condition, the gauge should
read at least 6.400 - 7,400 kpa (65 - 75 kgIlcm,,924- 1,067 psi). A low reading means pump output is
too low for full assist. Repair or replace the pump.

Install the clamp or ad,ustable clamp at the specified
distancs from the hose end as shown in the drawing.
. Add the power steering fluid to the specilied level on
the reservoir and check fo. leaks (see page 17-23).

Put ov6r the pipe untilthe hose stops at the$opper.
