On-Vehicle Inspection and ServiceNGS0000H
CHECKING RELIEF OIL PRESSURE
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-off valve fully opened. If
engine is started with shut-off valve closed, fluid pres-
sure 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 pressure gauge for more than 10 seconds.
4. After measurement, open shut-off valve slowly.
If relief oil pressure is outside the specification, disassemble and repair oil pump. Refer to PS-29, "Dis-
assembly and Assembly" .
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-6, "
Air Bleeding Hydraulic System" .
