1999 HONDA CIVIC Power steering 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 beltafter running engine for five minutes.
Inspection
Attach the special tool to the belt and measure the ten-sion of the belt.

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 andpump belt tension.
CAUTION: Disconnect the high pr$sure hos€ with care
so as not lo spill the power sieering tluid on tha frame
and other parts.
1. Disconnect the outlet line from the Dumo outlet fit-
ting, then installthe P/S joint adaptor (pump) on the
Dumo outlet.
2. Connect the P/S joint adaptor (hose) to the power
steering pressure gauge, then connect the outlet
hose to the adaptor.
3. Install the power steering pressure gauge to the P/Sjoint adaptor (pump) as shown.

7.
Start the engine and let it idle.
Turn the steering wheel from lock-to-lock several
times to warm the fluid to operating temperature.
Measure steady-state fluid pressure while idling. If
the pump is in good condition, the gauge should
read less than 1500 kPa (15 kgf/cmr, 213 psi).
lf it reads high, check the outlet line or valve body
unit (see General Troubleshooting 17-22).
Close the pressure control valve, then close the
shut-off valve gradually until the pressure gauge
needle is stable. Read the oressure.
lmmediately open the pressure control valve fully.
GAUTION: Do not keep lhe prossure control valve
clos€d more then 5 soconds or the pump could be
damagod by over-heating.
lf the pump is in good condition, the gauge should
read at least 6,400 - 7,400 kPa (65 - 75 kgflcm,, 920 -
1,070 psi). A low reading means pump output is too
low for full assist. Repair or replace the pump,

Installthe pump belt.
CAUTION:
. Make sure that the power steering belt is prop-
orly positioned on the pulleys.
. Do not get power stoering tluid or grease in the
power steering bsh or pulley faces. Clean off any
fluid or grease before installrtion.
Adjust the pump belt (see page 17-32).
Fill the reservoir to the upper level line (see page

Disassembly
CAUTION: The power steering components are made of aluminum. Avoid damaging the components during assembly.
NOTE:
. Ctean the disassembled parts with a solvent, and dry them with compressed air. Do not dip the rubber parts in a sol-
vent.
. Alwavs replace the O-rings and rubber seals with new ones before assembly.
. Apply recommended power steering fluid to the parts indicated in the assembly procedures'
. Do not allow dust, dirt, or other foreign materials to enter the power steering system.
. Replace the pump as an assembly ifthe parts indicated with asterisk (*) are worn or damaged'
