GWFLORID will build 1.3L (GW413EF, GW4G13) or 1.5L (GW4G15) gasoline engines, in which the
GW4G13 and GW4G15 engines will both incorporate the newest VVT technology which meets the Euro IV
emission standards. GWFLORID features McPherson technology on its chassis system. With an ultra light
body made from structural steel and high-intensity front and rear fender impact beams as well as a collision
impact absorption system, it is able to maintain the cab's integrity and safety to greater extent. We wrote this
maintenance manual in order to meet the demand of Great Wall after-sales service technicians. This manual
mainly introduces the areas of importance in regard to maintenance and care, and removal and installation of
each system's assembly and maintenance technical parameters.
To reduce the possibility of injury or property damage, read and follow t\
he instructions carefully:
This manual is provided by the Great Wall Motor Co., Ltd, and is written for the technician use. Any
maintenance or repair without proper prior training and tools or devices may result in personal injury of the
person performing the maintenance or others in the vicinity. It is also possible that damage to the vehicle will
occur or will lead to mechanical failure during normal operation.
Correct vehicle maintenance and repair is essential for the safety of the person performing regular
maintenance as well as the vehicle itself. If there is any component that needs to be replaced, use a
component with the same serial number or a serial number specified by the Great Wall Motor Co., Ltd. Never
use any part that has not been authorized by the Great Wall Motor Co., Ltd.
Any maintenance procedure introduced in this manual is effective for maintenance and repair. Some of
these procedures need specially designed tools.
Therefore, before using any vehicle part following any maintenance procedure or working with a tool
that has not been authorized by the Great Wall Motor Co., Ltd, check to make sure that none of the above
will endanger the safety of the person performing the work or the correc\
t operation of the vehicle.
This manual includes multiple "Warnings" and "Cautions," which should be strictly followed, so as to
reduce the possibility of injury during maintenance or repair. Improper maintenance or repair of the vehicle
may cause potential safety hazards. These "Warnings" and "Cautions" are not exhaustive. It is impossible for
the Great Wall Motor Co., Ltd, to warn against all the potential dangers caused by not properly following the
instructions.
Please read carefully the "Areas of Importance" before carrying out any maintenance or repair on the
airbag system's components or its surrounding electrical components. Action contrary to any of the "Areas of
Importance" may lead to the deployment of the airbag, resulting in injur\
y or unnecessary repair of the airbag.
To avoid accidental deployment of the airbag and its resulting injury, we suggest repairing the airbag
system before other vehicle systems if the airbag and the other vehicle \
systems both need repairing.
We have received generous support and help from many professional technicians during the preparation
of this manual. We would like to express our heartfelt gratitude to all of them.
Although we have tried our best to write this manual well, we do not guarantee that the entire content
in this manual is absolutely correct. Users may not make any legal claim against the Great Wall Motor Co.,
Ltd. in regards to this manual. Any loss caused by using this manual is not our responsibility. Because of
the writer's limited experience, there are likely mistakes in this manual, therefore we welcome any user
comments, suggestions, and corrections.
Great Wall Motor Co., Ltd. reserves the final right of explanation.

any vehicle part change is necessary, please use a part with
the same part number or part number specified by the Great
Wall Motor Co., Ltd. Never use a part that has not been au-
thorized by the Great Wall Motor Co., Ltd.

Transmission's Proper Use and Care
1. Transmission's proper operation
1.1 Shift the gear gently, not excessively.
1.2 Do not start with high speed.
1.3 To avoid premature abrasion of the gear shift fork, do not rest your hand on the \
gear lever while driving.
2. Model number of the lubricant to be used:
GL-4 80W-90 (For China domestic model)
GL-4 75W-90 (For alpine region model)
GL-5 140 (For high-temperature region model)
Caution: Please only use the lubricant with model numbers specified by t\
he Great Wall Motor Co., Ltd.
Do not mix lubricants with different model numbers. Only fill with clean lubricant.
3. Areas of importance for new vehicle usage:
3.1 Before using a new vehicle, be sure to check the transmission and all exposed connectors and fastening
pieces, so as to avoid failure due to faulty installation or loose conne\
ctions.
3.2 Since the new vehicle is still in the run-in period, the transmission's lubricant should be replaced after 5000 km
distance.
4. Transmission three-level maintenance:
4.1 Transmission level-one maintenance: During the first level of maintenance, the liquid level of the lubricant
should be checked to ensure that it is up to the oil-filling mouth. Add more if insufficient. Excessive low
oil level can lead to ineffective lubrication, as well as burning of the bearings and gears. Excessive high oil
level, however, can overheat the transmission or cause oil to leak. In addition, during the first level of main-
tenance, the breather plug should be checked and cleaned. If the breather plug is clogged, internal pressure
will build up and oil will leak from the transmission.
4.2 Transmission level-two maintenance: The transmission's lubricant should be replaced the first time that the
vehicle undergoes the second level of maintenance. Clean the transmission with kerosene. The quality of the
lubricant should be inspected during the future second level of maintenance practises. The lubricant should
be replaced if diluted, gummy, or dirty.
4.3 Transmission level-three maintenance: During the third level of maintenance, it should be removed for in-
spection, cleaning, and oil changing.

3. Installing the ABS rear wheel speed sensor with brack-
et assembly.
Use three hexagon head bolts, spring washers, and flat
washer subassembly connecting pieces to connect the sensor
to the rear hub unit, rear twist beam, and vehicle body.
ABS General Problem Maintenance and Areas of Importance
Common problems and solutions
1. When braking, the ABS hydraulic pressure unit noise is overly loud.
When the ABS is working, the motor inside the hydraulic pressure unit is ceaselessly rotating. At this time the
driver can feel the brake pedal bouncing back. However, this bounce back feeling will be entirely different
depending on the speed and road condition. Also, when performing an actuator movement test, the sound of the
running motor may also be sensed. When the vehicle is being driven and the brake is off, the sound of the motor
running can still occasionally be heard. This is the ABS undergoing component inspection, not a malfunction.
If the ABS hydraulic pressure unit noise is irregular, a movement test can be initiated. Compare the noise to that
of normal vehicles to determine if ABS hydraulic pressure unit noise is abnormal.
2. Inlet and outlet solenoid valve failure.
Once the ignition switch is ON, the ABS control unit automatically initiates a self-check. If an inlet and outlet solenoid
valve short circuit or open circuit is found, it will record the failure, light up the fault light, and abort the operation. If using a
scanner to adjust the problem code, make sure to use the movement test t\
o confirm that the solenoid valve has a problem and
then replace the hydraulic pressure unit directly.
X431 data flow: While the ABS is functioning, the inlet and outlet solenoid valves rapidly change operating
conditions.
EVFL - Front inlet valve LHOff / On
AVFL - Front outlet valve LHOff / On
EVFR - Front outlet valve RHOff / On
AVFR - Rront outlet valve RHOff / On
EVRR - Rear inlet valve LHOff / On
AVRR - Rear outlet valve LHOff / On
EVRR - Rear inlet valve RHOff / On
AVRR - Rear outlet valve RHOff / On
3. Wheel speed sensor malfunction.
With the engine running, use a oscilloscope to measure the voltage between the sensor's signal line and the
ground.
Output signal when wheel is stationary:
Output signal when the wheels are rotating: signal type is 0.44 V and 1.26 V square wave signal, duty cycle: 50: 50.
