Troubleshooting
General Troubleshootin g
Check the following before you begin:
. Has the suspension been modified in a way that would affect steering?
. Are tire sizes, tire variety and air pressure correct?
. ls the steering wheel original equipment or equivalent?
. ls the power steering pump belt properly adjusted?
. ls steering fluid reservoir filled to proper level?
. ls the engine idle speed correct and steady?

Fluid Replacement
Check the reseryoir at regular intervals, and add the rec-
ommended fluid as necessary.
CAUTION: Always use Gsnuine Honda Power Steering
Fluid-V or S. Using any other type of power steering
tluid or automatic transmission fluid can cause increassd
wear and poor steering in cold w3athel.

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.

10. Check the idler pulley bearing for play and drag,
and replace it with a new one if it's noisy or has
excessive play or drag.
lnstall in the reverse order of removal. Make note of
the following items,
. lf you're installing a new compressor, drain all the
reJrigerant oil from the removed compressor, and
measure its volume. Subtract the volume of
drained oil trom 130 m/ 14 U3 fl'o2,4.6 lmp'oz);
the result is the amount of oil you should drain
lrom the new compressor (through the suction fit-
trngl.
. Replace the O-rings with new ones at each fit-
ting, and apply a thin coat o{ refrigerant oil
before installing them. Be sure to use the right
O-rings for HFC-134a (R-134a) to avoid leakage.
. Use refrigerant oil (SP-10) for R-134a KEIHIN spi-
ral type compressors only.
. To avoid contamination, do not return the oil to
the container once dispensed, and never mix it
with other refrigerant oils.
. lmmediately after using the oil, replace the cap
on the container. and seal it to avoid moisture
aDsorprlon.
. Do not spill the refrigerant oil on the vehicle; it
may damage the paint; if the retrigerant oil con-
tacts the Daint, wash it off immediately.
. Adjust the Ay'C compr'essor b€lt (see psge 22-69)
and the power steering pump belt {see section
17t.
. Charge the system (see page 22-611, and test its
performance (see page 22-56]-.
