2006 QX56
5. Install Tools.
6. Start the engine and warm it up to normal operating temperature.
7. Check the engine oil pressure with engine running under no-load.Engine oil pressure [Engine oil temperature at 80 °C (175 °F)]
Unit: kPa (kg/cm2
, psi)
CAUTION:
If the difference is extreme, check the oil passages and oil pump for leaks and blockages.
8. After the inspections, install oil pressure sensor as follows:
a. Remove old liquid gasket adhering to oil pressure sensor and engine.
b. Apply liquid gasket and tighten oil pressure sensor to the specification. Use Genuine RTV Silicone Sealant or equivalent. Refer to GI-46, "
Recommended Chemical Prod-
ucts and Sealants" .
c. After warming up engine, make sure there is no leakage of engine oil with engine running.
Changing Engine OilEBS00LMT
CAUTION:

Be careful not to burn yourself, as the engine oil is hot.

Prolonged and repeated contact with used engine oil may
cause skin cancer; try to avoid direct skin contact with
used engine oil. If skin contact is made, wash thoroughly
with soap or hand cleaner as soon as possible.
1. Remove engine front undercover using power tool.
2. Warm up engine, and check for oil leakage from engine compo- nents. Refer to LU-7, "
OIL LEAKAGE" .
3. Stop engine and wait for 10 minutes.
4. Loosen oil filler cap, then remove drain plug.
5. Drain engine oil.
6. Install drain plug with new washer.
CAUTION:

Be sure to clean drain plug and install with new washer.
7. Refill with new engine oil. Refer to MA-11, "
Fluids and Lubricants" .

INSPECTION AFTER DISASSEMBLY
Boot
Check boot for tears, cracks and deformation. Replace if necessary.
Gear Housing Assembly
Check gear housing assembly for dents, cracks or damage. Replace as an assembly if necessary.
Outer Socket and Inner Socket
SWING TORQUE

Measure the swing torque, using Tool. When ball stud and inner
socket start moving the measured value must be within the
specification. If the reading is outside the specification, replace
the socket.
ROTATING TORQUE

Measure the rotating torque, using Tool. If the value is outside
the specification, replace the outer sockets.
AXIAL END PLAY

Apply a load of 490 N (50 kg-f, 110 lb-f) to the ball stud axially.
Use a dial gauge to measure the amount of the movement that
the stud makes. If the value is outside the specification, replace
the sockets. Tool number : — (J-44372)

On-Vehicle Inspection and ServiceEGS000UJ
CHECKING RELIEF OIL PRESSURE
CAUTION:
Before starting work, confirm belt tension is proper.
1. Connect Tool 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 – 80 °C (122 – 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, repair or replace oil pump. Refer to PS-22, "Disassem-
bly and Assembly" .
5. After inspection, disconnect oil pressure gauge and oil pressure gauge adapter from hydraulic circuit, con- nect 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" .
Removal and InstallationEGS000UK
REMOVAL
1. Drain power steering fluid from reservoir tank.
2. Remove engine room cover. Refer to EM-12, "
Removal and Installation" .
3. Remove air duct assembly. Refer to EM-15, "
Removal and Installation" .
4. Remove power steering reservoir tank.
5. Remove serpentine drive belt belt from auto tensioner and power steering pump. Refer to EM-13,
"Removal and Installation" .
6. Disconnect pressure sensor electrical connector.
7. Remove high pressure and low pressure piping from power steering oil pump. Refer to PS-23, "
HYDRAU-
LIC LINE" .
8. Remove mounting bolts, then remove power steering pump.
INSTALLATION
Installation is in the reverse order of removal. Refer to PS-23, "HYDRAULIC LINE" for tightening torque.

After installation, bleed air. Refer to PS-6, "Air Bleeding Hydraulic System" .
NOTE:
Belt tension is automatic and requires no adjustment.
