Humming due to pulsation oI lluid is normal, particularly when the wheel isturned with the vehicle stoooed.
Outlet hose (High-pressure hose)touching the frame.
Right cylinder end seal squeak.
Pump noise, though not loud, from tho valv6 body unit can be heard when turn-ing the steering wheel to full lock in either direction. This is normal. Do not hold

Inspection and Adjustment
Steering Operation
Place the front wheels in the straight ahead position and
measure the distance the steering wheel can be turned
without moving the front wheels.
ROTATIONAL PLAY: 0 - 10 mm {0 - 0.39 inl
lf the play exceeds the service limit. perform rack guide
adiustment (see page 17-211.
lf the play is still excessive after rack guide adjustment.
inspect the steering linkage and gearbox as described
on the neld page.
Power Assist Check with
Vehicle Parked
Check the power steering fluid level (see page 17-
21) and pump belt tension (see page 17-201.
Start the engine, allow it to idle. and turn the steer
ing wheel from lock-to-lock several times to warm
up the fluid.
Attach a spring scale to the steering wheel. With the
engine idling and the car on a clean. dry floor. pull
the scale as shown and read it as soon as the tires
begin to turn,
4. The scale should read no more than 34 N (3.5 kgf,
7.7 lbf). lf it reads more, check the gearbox and
pump.

Inspection and Adjustment
Pump Belt
NOTE: When using a new belt, first adjust the deflection
or tension to the values for the new belt, then readjust
the deflection or tension to the values for the used belt
after running engine for five minutes,
Inspection
Attach the soecial tool to the belt and measure the ten-
sion of the belt.
Tension:
Usad Belt: 390 - 54O N {/10 - 55 kgf. 88 - 120 lbf}
Nsw Belt: 740 - 880 N {75 - 90 kgf. 170-2(X)lbf)
NOTE:
. lf there are cracks or any damage evident on the belt,
replace it with a new one.
. Follow the manufacturer's instructions for the tension
gauge.

Adiustment
1. Loosen the power steering pump mounting bolts.
2. Turn the adjusting bolt to get the proper belt ten-
sion, then retighten the bolts.
3. Stan the engine and turn the steering wheel from
lock-to-lock several times. then stop the engine and
recheck the deflection of the belt.

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: Take care not to spill thq fluid on lhe
body and parts. Wipe off any spilled fluid al onc€.
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.

RETURN HOSE{From the oilcooler)
4. Reinstallthe return hose on the reservoir.
5. Fill the reservoir to the uDDer level line.
6. Start the engine and run it at fast idle, then turn the
steering from lock-to-lock several times to bleed air
from the system,
7. Recheck the fluid level and add some it necessary.
CAUTION: Do not lill the reservoir boyond thc

NOTE: Perform rack guide adjustment with the wheels
in the straight ahead position.
1. Loosen the rack guide screw locknut with the spe-
cialtool, then loosen the rack guide screw.
Tighten the rack guide screw until it compresses the
spring and seats against the rack guide, then loosen
it.
Retighten ihe rack guide screw to 3.9 N.m (0.4
