Nissan Maxima Service and Repair Manual: Power steering oil pump
Inspection
CAUTION: Make sure that belt tension is
normal before starting the following procedure.
- Connect the Tool between oil pump discharge connector and
high-pressure hose. Bleed air from the hydraulic circuit while opening
the shut-off valve fully. Refer to ST-12, "Inspection".

Tool numbers : KV48103500 (J-26357)
: KV48102500 (J-33914)
- Start engine. Run engine until power steering fluid temperature
reaches 50 - 80C (122 - 176F).
CAUTION:
- Leave the shut-off valve of the Tool fully open while starting
and running engine. If engine is started with the shutoff valve closed,
the hydraulic pressure in oil pump goes up to the relief pressure along
with unusual increase of power steering fluid temperature.
- Be sure to keep hose clear of belts and other parts when
engine is started.
- Fully close the shut-off valve with engine at idle and measure
the relief oil pressure.
CAUTION: Do not keep shut-off valve closed
for 10 seconds or longer.
- Open the shut-off valve slowly after measuring. Replace oil pump
if the relief oil pressure is outside the standard.
- After inspection, disconnect the Tool from hydraulic circuit, then
add power steering fluid and perform air bleeding. Refer to ST-12,
"Inspection".
