CHECKING RELIEF OIL PRESSURE (VK45DE 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-off valve fully opened. If engine is started with shut-off valve 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 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-37, "
Disas-
sembly and Assembly (VK45DE 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-8, "
Air Bleeding Hydraulic System" .

Removal and Installation (VQ35DE Models)NGS000C6
REMOVAL
1. Remove undercover from vehicle with power tool.
2. Loosen belt tensioner adjust screw, then remove belt from oil pump pulley. Refer to EM-15, "
DRIVE
BELTS" .
3. Drain power steering fluid from reservoir tank.
4. Remove piping of high pressure and low pressure (drain fluid from their pipings). Refer to PS-41,
"HYDRAULIC LINE" .
5. Remove mounting bolts, then remove power steering pump.
INSTALLATION
Refer to PS-41, "HYDRAULIC LINE" for tightening torque. Install in the reverse order removal.
After installation, adjust belt tension. Refer to EM-15, "DRIVE BELTS" .
After installation, bleed air. Refer to PS-8, "Air Bleeding Hydraulic System" .
Removal and Installation (VK45DE Models)NGS000C7
REMOVAL
1. Remove undercover from vehicle with power tool.
2. Remove power steering oil pump belt from auto tensioner. Refer to EM-174, "
DRIVE BELTS" .
3. Drain power steering fluid from reservoir tank.
4. Remove piping of high pressure and low pressure from power steering oil pump (drain fluid from their pip- ings). Refer to PS-41, "
HYDRAULIC LINE" .
5. Remove mounting bolts, then remove power steering pump.
INSTALLATION
Refer to PS-41, "HYDRAULIC LINE" for tightening torque. Install in the reverse order removal.
After installation, bleed air. Refer to PS-8, "
Air Bleeding Hydraulic System" .
NOTE:
Adjustment of belt tension is no necessary because engine of this model equips auto tensioner.
