Inspection

Connect the Tool between power steering oil pump discharge connector and high-pressure hose. Bleed air from the hydraulic circuit while opening valve fully. Refer to Air Bleeding Hydraulic System.

Tool numbers

: KV48103500 (J-26357)

: KV48102500 (J-33914)

Start engine. Run engine until power steering fluid temperature reaches 50° - 80°C (122° - 176°F).

CAUTION:

Leave the valve of the hydraulic pressure gauge fully open while starting and running engine. If engine is started with the valve closed, the hydraulic pressure in power steering oil pump goes up to the relief pressure along with unusual increase of fluid temperature.

Be sure to keep hose clear of belts and other parts when engine is started.

Fully close the Tool valve with engine at idle and measure the relief oil pressure.

Relief oil pressure

: Refer to Power Steering Oil Pump.

CAUTION:

Do not keep valve closed for 10 seconds or longer.

Open the valve slowly after measuring. Replace the power steering oil pump if the relief oil pressure is outside the standard.

After inspection, disconnect the Tool from hydraulic circuit, then add fluid and bleed air. Refer to Air Bleeding Hydraulic System.
