Relief Oil Pressure
WARNING: This page is about a different car, the 2018 Nissan Maxima. However, it is still accessible from the selected car via links, so may be relevant.
- Connect Tool between power steering oil pump discharge connector and high-pressure hose. Bleed air from hydraulic circuit while opening valve fully. Refer to Air Bleeding Hydraulic System .
Tool numbers
: KV48102500 (J-33914)
- Start engine. Run engine until power steering fluid temperature reaches 50° - 80°C (122° - 176°F).CAUTION:
- Leave valve of hydraulic pressure gauge fully open while starting and running engine. If engine is started with valve closed, hydraulic pressure in power steering oil pump goes up to 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 Tool valve with engine at idle and measure relief oil pressure.
Relief oil pressure
: Refer to Power Steering Oil Pump
CAUTION: Do not keep valve closed for 10 seconds or longer. - Open valve slowly after measuring. Replace power steering oil pump if relief oil pressure is outside specification.
- After inspection, disconnect Tool from hydraulic circuit, then add fluid and bleed air. Refer to Air Bleeding Hydraulic System .
