On-Vehicle Inspection and ServiceINFOID:0000000001327718
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".

• Check for the correct installation status prior to removal or disassembly. If matching marks are required, becertain they do not interfere with the function of the parts when applied.
 Overhaul should be done in a clean work area, it is preferable to work in dustproof area.
 Before disassembly, using steam or white gasoline, completely remove sand and mud from the exterior of
the unit, preventing them from entering into the unit during disassembly or assembly.
 Check appearance of the disassembled parts for dam age, deformation, and unusual wear. Replace them
with a new ones if necessary.
 Gaskets, seals and O-rings should be replaced any time when the unit is disassembled.
 In principle, tighten bolts or nuts gradually in several steps working diagonally from inside to outside. If tight-
ening sequence is specified, observe it.
 Clean and flush the parts sufficiently and blow-dry them.
 Be careful not to damage sliding surfaces and mating surfaces.
 When applying sealant, remove the old sealant from t he mounting surface; then remove any moisture, oil,
and foreign materials from the application and mounting surfaces.
 Always use shop paper for cleaning the inside of components.
 Avoid using cotton gloves or shop rags to prevent entering of lint.
 During assembly, observe the specified tightening tor que, and apply new gear oil, petroleum jelly, or multi-
purpose grease as specified for each vehicle, if necessary.
