Troubleshooting
Noise and Vibration
NOTE: Pump noise in first 2 - 3 minutes after starting in cold weather is normal.
Humming
Rattle or chattering
Humming due to pulsation of fluid is normal, particularly when the wheel isturned with the vehicle stooDed.
lf equipped with automatic trans-mission, the hum could be thetorque converter or pump noase.
Confirm by temporarily removingthe pump belt.
Feed hose (high-pressure) touch-ing the frame.Beposition the feed hose.
Loose steering shaft connector,tie-rod, or balljoint.Check and tighten, or replaceparts as necessary,
Column shaft wobbling.Roplace the column assembly.
Check the rack guide for properadjustment (see page 17-15).Adjust, if necessary.
Rattling sound and feeling when turning the steering wheel right and left with th€engine OFF is normal.
Pump noise, though not loud, from the valve body unit can be heard when turn-ing the steering wheel to full lock in either direction. This is normal. Do not holdthe steering wheel at full lock lor more than five seconds when inspecting.

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 limit, perform rack guide adjust-
ment (see page 17-15).
lf the play is still excessive after rack guide adjustment,
inspect the steering linkage and gearbox as described
on the next page.

1. Check the power steering fluid level (see page 17-
15) and pump belt tension (see page 17-14).
2. Start the engine, allow it to idle, and turn the steer-
ing wheel from lock-toiock several times to warm
up the fluid.
3. Aftach a spring scale to the steering wheel, With the
engine idling and the vehicle on a clean. dry floor,
pull the scale as shown and read it as soon as the
tires begin to turn.
SPRINGSCALE(Commercially
available)
The scale should read no more than 29 N (3.0 kgf,
6.6 lbfl. lf it reads more, check the gearbox and
oumo.

Inspection and Adjustment
Pump Belt
When using a new belt. first adjust the deflection or ten-
sion 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
Note these items during inspection:
a lf there are cracks or any damage evident on the belt,
replace it with a new one.
. Follow the manufacturer's instructions lor the tension
gauge.
'1. Remove the P/S reservoir from the bracket, and set
it aside.
2. Attach the belt tension gauge to the belt with the
gauge face toward the engine, and measure the ten-
sion of the belt.
Remove the belt tension gauge carefully to avoid
hitting the gauge reset lever.
Tension:
Used Belt: 390 - 540 N {40 - 55 kgf, 88 - 121 lbf)
New Belt: 7,[0 - 840 N (75 - 90 kgf, 165 - 198 lbf)

Fluid Replacement
Check the reseryoir at regular intervals, and add the rec-
ommended fluid as necessary.
CAUTION: Always use Gsnuine Honda Power Steering

1.Raise the reservoir. then disconnect the return hose
to drain the reservoir. Take care not to spill the fluid
on the body and parts. Wipe off any spilled fluid at
once.
2, Connect a hose of suitable diameter to the discon-
nected return hose, and put the hose end in a suit-
able container.
3. Stan 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.
4. Beinstallthe return hose on the reservoar.
5. Fill the reservoir to the upper 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 if necessary.
Do not fill the reservoir beyond the upper level line.

8. Turn the steering wheel from lock-to-lock severaltimes to warm the fluid to operating temperature.
9, Measure steady-state fluid pressure while the engineis idling. lf the pump is in good condition, the gauge
should read less than 1,500 kPa (15 kgf/cmr, 213 psi).
lf it reads high, check the outlet hose or valve bodvunit (see General Troubleshooting).
10. Close the pressure control valve, then close theshut-off valve gradually until the pressure gauge
