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°.

1. Configuration introduction
The GWFLORID comes in three configurations: comfort, luxury and elite. The wire harness has two types of
configurations: One is a non jam protection comfort model, which is a combination of both comfort and luxury
type, the other type is called elite. These two configurations are universally used in most of this manual. The
parts that are only available for the non jam protection comfort type have been marked in this manual, please
pay attention to these sections while performing maintenance.
2. Fuse box and power supply introduction
The fuse box located inside the left side of the dashboard is No. 1 Fuse Box, the other one inside the left side of
the engine compartment is No. 2 Fuse Box.
• 30 represents a power cord for normal power, which is from the battery positive fuse box-60 A.
• 30a represents a power cord for normal power, which is from the battery positive fuse box-120 A.
• 30b represents a power cord for normal power, which is from the battery positive fuse box-120 A.
• 15 represents a power cord for small capacity electronics. When the ignition switch is at the "ON" position,
power is supplied by relay IG.
• 15a represents a power cord for small capacity electronics. When the ignition switch is at the "ON"
position, power is directly supplied by ignition switch IG1.
• 15b represents a power cord for small capacity electronics. When the ignition switch is at the "ON"
position, power is directly supplied by ignition switch IG2.
• X represents a power cord for small capacity electronics. When the ignition switch is at the "ACC"
position, power is supplied by relay ACC.

Areas of importance in circuit maintenance
1. Before operating any electronic devices, and when tools or maintenance devices may easily make
contact with an uncovered electronic terminal, please make sure to turn the ignition switch to the LOCK
position, and then disconnect the battery's negative cable to avoid injury or vehicle damage. When the
ignition switch is on the ON position, please do not disconnect the battery's connecting wire or take out
the power's fuse, regardless if the engine is running or not.Otherwise it would seriously damage the
ECU and related microelectronic devices such as sensors.
2. When changing the fuse, please make sure that the new fuse possesses the proper current rating,
and is not above or below this rating.
3. When repairing the wire harnesses of the airbag and pretensioner, only specified contact points,
plugs, and wires are allowed to be used.
4. Before repairing the wire harness, make sure to eliminate any factor that might cause damage,
for example, the edge of a vehicle body part is too sharp, or the used electronics are damaged or
corroded.
5. Shielded wire should not be repaired, it must be replaced entirely once it is damaged.
6. Unless it is specified during the test, please do not use an analog multimeter to test the ECU and
sensor, instead use a high-impedance digital multimeter (internal resistance should be ≥10 kΩ) or a
vehicle multimeter for inspection.
7. When inspecting the connector with a digital multimeter, take the waterproof rubber cover off the
connector, and tightly insert the test pen along the connecting terminal. Don't use too much force, as
to avoid cracking the connector.
Circuit inspection steps
The principle of troubleshooting is to confirm the "possible cause". Once the possible cause is confirmed, the
components that need to be inspected are limited to the components that are related to the possible cause. The
confirmed possible cause should be based on theory and be supported by facts, but not just by intuition. If
one tries to solve the problem but does not adopt the proper troubleshooting steps, it may make the problem
worse. Then the possible cause not only can't be confirmed, but also maintenance can't be performed properly.
Troubleshooting should adhere to the four steps below:
1. Observe the symptoms carefully, inspect if there is anything else abnormal, and record it.
2. While confirming the possible causes, study the circuit diagram carefully, and regard it as a whole
system in order to understand the circuit. Thorough knowledge of switches, relays, and other
electronic components is obligatory for proper analysis.
3. Inspect and eliminate the problems one by one until the cause is found.
4. After the malfunction is fixed, make sure to check if the inspected system is working properly, and also
check if the maintenance may have caused any new problems.
