Steering System Maintenance
Structure Introduction
The steering wheel has an airbag module which should only be inspected and repaired by a professional. The
steering column's upper section adopts a steel deformation and energy absorbing crumple structure which
ensures collision protection for the driver. The lower section uses a high precision sliding spline structure,
which can effectively eliminate structural interference caused by body deformation. The steering column angle
is adjustable, which can more easily adapt to the driver, and at the same time possesses reasonable reverse
efficiency to ensure the driver has a good feel for the road. Steering sys\
tem is as shown below:
Steering column assembly removal and
installation
1. Remove the airbag.
(a) Disconnect the battery's negative cable, and wait for
one minute before canceling the airbags function in
order to avoid unnecessary injury.
(b) To ensure steering column's proper installation, during
the entire removal process, the front tires must keep
straight.
(c) Remove the two hexagon screws and the airbag module.

Removal and installation of the power
steering pump on the engine:
Remove the power steering pump after removing the high
pressure port of the power steering pipeline and steering
pump, as well as the inlet hose.
1. Loosen and adjust the bracket's hexagon bolts
Q1401025 (M10×1.25) with a M13 socket wrench,
l o o s e n t h e p u m p b e l t a r e a , a n d t h e n r e m o v e t h e
steering pump belt.
2. Loosen the hexagon flange mounting bolt Q1841090
(M10×1.25). After pulling out the hexagon flange mounting
bolt, complete the disassembly of the steering pump.
3. Tightening torque for installing the tension regulator
bracket: 40±4 N·m.
Install the tightening torque of the steering pump
mounting bracket: 25±3 N·m
4. After the installation of the power steering pump and
steering pump belt is completed, adjust the tension
of the entire power steering pump belt. Belt tension
should be 450±50 N.
Use an exertion force of 98 N in the middle of the belt.
Belt deflection should be 4-6 mm.
Power Steering Fluid Instructions
Replace the power steering fluid in the following situations:
1. After driving a new vehicle for 6000 km.
2. After replacing any part of the power steering gear, power steering pump and steering pipeline.
3. Driving 6000 km after replacing power steering gear and power steering p\
ump.
Caution:
1. The expelled power steering fluid after replacing power steering compone\
nts cannot be reused.
2. Only use ATF DEXRON III power steering fluid.
3. No matter when the PS fluid reservoir level drops, check the PS fluid reservoir, steering pump, power
steering gear, and steering pipeline, as well as all the connections.
Methods:
Two people are required to add power steering fluid. With the engine off, one person pours the fluid
into the PS fluid reservoir, while the other repeatedly turns the steering wheel from lock to lock for
more than 10 laps, until the steering fluid level is between MAX and MIN. Start the engine and turn
the wheel from lock to lock again (Caution: Do not leave it at the two extreme points for more than 5s).
When the fluid level goes down, refill the steering fluid until it is be\
tween MAX and MIN.
Technical Requirements
1. Mounting bolts with thread fastening glue for the power steering gear, tightening torque is 107±7 N·m
The coupling torque for the steering gear's tie rod and tie rod ball is \
74±7 N·m
The coupling torque for the steering tie rod ball stud and steering knuc\
kle is 49±5 N·m
2. The tightening torque for the steering column assembly and steering gear assembly's secure coupling
bolt is 25±3 N·m
The coupling bolt torque for the steering column and dashboard brace rei\
nforcement is 25±3 N·m
Torque for the fixed steering wheel nut on the upper section of the steer\
ing column is 50±4 N·m
3. Fasten the steering wheel center
Keep the front wheel pointed straight ahead, make sure not to change the direction of the steering rod, and
take down the steering wheel. Install the steering wheel in the center. The steering wheel's radial should be
in the middle, and the Great Wall logo should be in the direct sight of the driver, then tighten nuts.
Tightening torque: 50±5 N·m
4. Steering wheel free clearance inspection
Keep the vehicle centered, stop the engine, and turn the wheel left with a force of about 5 N. If
resistance is felt, stop when the resistance increases. Then turn right and stop under the same
situation. Measure the angle that the steering wheel turns along the outer edge. The angle value
measured is the steering wheel's free clearance. Its standard value should be less than 20°, and from
the middle position it should not turn at a left or right angle larger t\
han 10°.

Combination Meter
If something is wrong with the meter, check the relevant component and circuit according to the connector defi-
nition. If the failure still cannot be eliminated, check whether the instrument itself has malfunctioned in the fur-
ther steps. The following diagram shows the view of the meter connector and its numb\
er.
