CHECKING RELIEF OIL PRESSURE (VQ35DE MODELS)
CAUTION:
Before starting work, confirm belt tension is proper.
1. Connect oil pressure gauge (SST) and oil pressure gauge adapter (SST) between oil pump discharge connector and high
pressure hose and then bleed air from the hydraulic circuit.
2. Start engine. Allow engine to run until tank temperature reaches 50 to 80 °C (122 to 176 °F).
CAUTION:
Warm up engine with shut-o ff valve fully opened. If engine
is started with shut-off val ve closed, fluid pressure in
power steering pump increases to maximum. This will
raise fluid temperature excessively.
Be careful not to contact hose with belt when engine is
started.
3. With engine at idle, close shut-off valve and read the relief oil pressure.
CAUTION:
Do not close shut-off valve of pressu re gauge for more than 10 seconds.
4. After measurement, open shut-off valve slowly. If relief oil pressure is outside the specificat ion, disassemble and repair oil pump. Refer to PS-29, "
Disas-
sembly and Assembly (VQ35DE Models)".
5. After inspection, disconnect oil pressure gauge ( SST) and oil pressure gauge adapter (SST) from hydrau-
lic circuit, connect oil pump discharge connector and high pressure hose. Add fluid and bleed air from
hydraulic circuit thoroughly.
Refer to PS-7, "
Air Bleeding Hydraulic System".
