8.

Wait several minutes and then re-check the oil
level in the oil pan.

The maximum liquid level rising height: 5 mm (0.20
in)

9.

In case of any problem discovered, exhaust air
from the power steering system. See 7.2.8.7
Power Steering System Air Exhausting
Procedures.

10. Re- checks oil fluid level height.

7.2.8.3 Steering hydraulic pressure inspection

1.

Disconnect oil outlet tube of power steering pump asembly refer to 7.2.8.6 replacement of power steering oil
intake and outlet tube.

2.

As shown in figure, install hydraulic force testing
tool.

Notes:

The valve of the tool shall be in the open position
when initial checking.

3.

For exhaust of power steering system, refer to
7.2.8.7 Exhaust procedures of power steering
system.

4.

Preheat power steering oil, start engine to make it
run at idle speed.

5.

Turn steering wheel from left bottom to right
bottom for several times to make oil temperature
increase.

Oil temperature preheat to :75 - 80℃(167 - 176 ºF)

6.

Keep the engine running in idle mode, close the
tool valve and observe and record the reaadings
from the pressure gauge.

Min. oil pressure: 6,400 kPa (928 psi)

If the power steering pump assembly is damaged due
to low oil pressure, replace the power steering pump
assembly damaged. Refer to 7.2.8.10 replacement of
power steering pump assembly.

Warning!

The special tool valve shall not be closed more than
5s; otherwise, the oil temperature is too high, so that
the power steering pump assembly will be damaged.

NL07-0006b

7.

Keep the engine running in the idle mode and
open the valve.

8.

Have the engine run at a RPM ranging from
1,000 to 3,000 to measure the oil pressure when
the engine revolving speed is 1,000 rpm and
3,000rpm.

oil pressure differential:490kPa (71 psi) or much less

Note: Do not turn the steering wheel.

If the power steering pump assembly flow control
valve is damaged due to excessive oil pressure
difference, repair or replace the power steering pump
assembly. refer to 7.2.8.10 replacement of power
Steering Pump Assembly.

If the hydraulic oil path of the power steering system
blocks or leaks, wash and repair the hydraulic pipeline
or replace the relevant parts.

NL07-0007b

9.

Have the engine run in idle mode, fully open the
valve and thoroughly turn the steering wheel
counterclockwise or clockwise to measure the oil
pressure.

Min. oil pressure:6. 400 kPa (928 psi)

If the power steering pump assembly leaks are
damaged due to low oil pressure, replace the power
steering pump assembly damaged. Refer to 7.2.8.10
replacement of power steering pump assembly.

If the hydraulic oil path of the power steering system
leaks, repair the hydraulic pipeline or replace the
relevant parts. Refer to 7.2.8.6 Replacement of power
steering Inlet and outlet oil pipe.

NL07-0008b

Notes:

The duration of the steering wheel in the steering limiting position does not exceed 5s; otherwise, the steering
pump may be damaged.

12. Drain air from power steering system, refer to 7.2.8.7 Exhaust process of power steering system.

7.2.8.4 Steering force inspection

Warning!

Warning: Refer to Warning for battery disconnection in Warnings and precautions.

1.

Stop the vehicle on flat rod, and make the vehicle wheel point to right front.

2.

Disconnect the battery negative cable. Refer to Battery Cable Disconnection/Connection Procedures.

Notes:

Wait at least 60 s after disconnecting the battery cable to prevent the airbag and the safety belt pre-tensioner from
being started.

3.

Dismantling of driver's side safety airbag, refer to
Replacement of driver's side safety airbag.

4.

Connect the battery negative cable.

5.

Check whether a correct tightening torque is
applied to the steering wheel fixing nut with a
torque wrench.

6.

Start the engine and have it run in idle mode.

7.

Turn the steering wheel counterclockwise and
clockwise by 90 degrees with a torque wrench to
check the steering torque during the
counterclockwise and clockwise rotation.

Steering force (reference): 5.5 Nm (metric) 4.1 lb-ft
(English system)

Notes:

Prior to inspection, the tire type, the tire pressure and
the contact surface must be firstly considered.

8.

Disconnect the battery negative cable.

9.

Re-check the torque of the steering wheel fixing
nut.

Torque:40 Nm (Metric) 29.6 lb-ft (English system)

10. Install the driver's side airbag.

11. Connect the battery negative cable.

7.2.8.5 Steering gear tie rod ball head inspection

1.

For dismantling of steering tie rod, refer to 7.2.8.11 replacement of steering tie rod and ball head.

2.

Fixing tie rod ball head onto caliper firmly.

3.

Install nut onto ball head bolt.

4.

Shake the upper ball bolt back and forth more
than 5 times.

5.

Then continuously rotate the nut cap with a
torque wrench at a speed ranging from 2 to
4rmp/s and read the torque for the 5th round.

Rotational torque :1.5-3 .0 Nm (1.1 - 2.2 lb-ft)

If the rotational torque is not within the specified
range, replace the tie rod assembly.

Notes:

The method for inspecting the left and right steering
gear tie rod ball heads is the same.
