• P/S joint adapter (hose) 07ZAK-S7CA200
• P/S pressure gauge 07406-0010001

Check the fluid pressure as follows to determine
whether the trouble is in the pump or gearbox.

1. Check the power steering fluid level (see page

17-12).

2. Disconnect the pump outlet hose (A) from the

pump outlet with care so as not to spill the power
steering fluid on the frame and other parts. Install
the P/S joint adapter (pump) on the pump outlet (B).

3. Connect the P/S joint adapter (hose) to the P/S

pressure gauge, then connect the pump outlet hose
(A) to the P/S joint adapter (hose).

4. Install the P/S pressure gauge to the P/S joint

adapter (pump).

5. Fully open the shut-off valve (A).

6. Fully open the pressure control valve (B).

7. Start the engine and let it idle.

8. Turn the steering wheel from lock-to-lock several

times to warm the fluid to operating temperature at
158 °F (70 °C).

9. Measure steady-state fluid pressure while the

engine is idling. If the pump is in good condition,
the pressure should be no more than 1,470 kPa
(15 kgf/cm , 213 psi). If the pressure is too high,
check for:

• Clogged or deformed feed or return line between

the pump and gearbox.

• Clogged valve body unit.

10. Raise the engine speed to 3,000 rpm, and measure

the fluid pressure. If the pump is in good condition,
the pressure should be at least 1,470 kPa
(15 kgf/cm , 213 psi). If the pressure is too high,
repair or replace the pump.

11. Lower the engine speed and let it idle. Close the

shut-off valve, then close the pressure control valve
gradually until the pressure gauge needle is stable.
Read the pressure.

Do not keep the shut-off valve closed more
than 5 seconds or the pump could be
damaged by overheating.

12. Immediately open the shut off valve fully. If the

pump is in good condition, the gauge should read
at least this specification:

A low reading means pump output is too low for
full assist. Repair or replace the pump (see page
17-14).

Fluid Replacement

A

Check the reservoir (A) at regular intervals, and add the
recommended fluid as necessary. Always use ACURA
Power Steering Fluid. Using any other type of power
steering fluid or automatic transmission fluid can cause
increased wear and poor steering in cold weather.

1. Raise the reservoir, then disconnect the return hose

(A) 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 (B) of suitable diameter to the

disconnected return hose, and put the hose end in a
suitable container.

3. Start the engine, let it run at idle, and turn the

steering wheel from lock-to-lock several times.
When fluid stops running out of the hose, shut off
the engine. Discard the fluid.

4. Reinstall the return hose on the reservoir.

5. Fill the reservoir to the upper level line (C).

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 more fluid if

necessary. Do not fill the reservoir beyond the
upper level line.

8. If the fluid is contaminated, dark, or discolored,

repeat this procedure as necessary.
