2008 GEELY MK engine

Geely “MK” series sedans (JL7132U,JL7132HU,JL7152U,JL7152HU,JL7162U) are brand
new superior models developed by Geely Group who has fully proprietary intellectual property
rights. As a result of the three years of involvements and efforts of the experts from Geely Automo-
bile Research Institute, these sedans reach international leading level in model design, power,
sense of comfort, safety and manufacturing technology while featured in beautiful appearance,
economy, environment protection and safety. The meaning of MK implied that Geely Automobile
has a great development from caterpillar to butterfly. With respect to the power, Geely “MK” series
sedans are equipped with 1.3L, 1.5L, and 1.6L EFI engines developed and manufactured by Geely
itself, and has reached “Chinese III” (Euro III) emission standard.
This manual contains a detailed description of the structures and principles, servicing and adjustment,
removal, assembling technology and matching clearance of the parts of the Geely “MK” sedans
with torque information of the bolts and nuts as well as schematic diagram for special tool operation.
This manual also introduces the transmission control system of the automatic transmission models,
vehicle electric circuits and elaborates ABS system, SRS, BOSCH M7.9.7 electronic control fuel
injection and ignition system, rear parking radar, sound, air conditioning and onboard hands-free
phone system. You can refer to this manual for the information about the regular maintenance,
servicing, adjustment, troubleshooting, removal and installation procedure, specific operations of
the “MK” sedans.
This manual covers the matching relation among the engine assembly, transmission assembly and
the vehicle, but does not have the further description of the structures and principles of the engine
and transmission assemblies and their servicing process. You can refer to the service manuals
solely prepared for engine assembly and transmission assembly for these information.
All information in this manual is based on the latest products released at the time of publication of
this manual. However, the specifications and procedures may need to be modified, and the subse-
quent change will be revealed in later versions.
This manual is prepared by Geely Automobile Research Institute under the assistance of technical
staff from Zhejiang Geely Automobile Co., Ltd and Geely International Corporation. Readers
discovering during the use of this manual the errors and careless omissions due to limited skills of

Make sure to wear the helmet and safety shoe
when more than 2 persons work together, be sure to pay mutual attention to the safety.
when it is required to run the engine, you have to pay attention to the ventilation of the workshop.
When handling the high-temperature, rotating, moving and vibrating parts, be careful not to be scalded
or hurt.
When lifting the vehicle, safety stand should be used to support the specified position.
When lifting the vehicle, safety devices should be used.
The diagnosis requires full understanding of the trouble and effective operation.
Before the parts are removed, check the assembly for distortion and damage.

General Information - Repair Instruction1-93. Electronic Control Device
(1) Removal of the battery terminal cable
a. Before performing electrical servicing, disconnect the nega-
tive (-) cable from the battery in order to avoid short for burnout.
b. When disconnecting the terminal cable, turn off the ignition
and light switches, loosen the cable nut and raise the cable straight
up without twisting or prying it.
c. When disconnecting the terminal cable from the battery, all
information stored in the clock, radio and DTC shall be deleted,
therefore, these information shall be checked before disconnection.
(2) Processing of Electronic Parts
a. Do not open the cover or case of the ECU unless absolutely
necessary. (If the IC terminals are touched, the IC may be destroyed
by static electricity.)
b. To pull apart electrical connectors, pull on the connector itself,
not the wires.
c. Be careful not to drop electrical components, such as ECU
or relays. If they are dropped on a hard floor, they should be replaced
and not reused.
d. When steam cleaning an engine, protect the electronic
components, air filter and emission-related components from water.
e. Never use an impact wrench to remove or install tempera-
ture switches or temperature sensors.
f. When checking continuity at the wire connector, insert the
tester probe carefully to prevent terminals from bending.
4. Remove and Installation of Engine Intake Parts
(1) If any metal scrap is mixed in the inlet pass, that may give
a bad effect to the engine.
(2) When removing and installing of the inlet system parts, close (6) Airbag ECU
a. Never reuse the airbag ECU involved in a collision when the SRS has deployed.
b. The connectors to the airbag sensor assembly should be connected or disconnected with the airbag ECU
mounted on the floor. If the connectors are connected or disconnected while the airbag ECU is not mounted to
the floor, it could cause undesired inflation of the supplemental restraint system.
c. Work must be started after 60 seconds from the time the ignition switch is turned to the "LOCK" position
and the negative (-) terminal cable is disconnected from the battery, even if only loosing the set bolts of the
airbag ECU.
(7) Wire Harness and Connector
The SRS wire harness is integrated with the instrument panel wire harness assembly. All the connectors in
the system are a standard yellow color. If the SRS wire harness becomes disconnected or the connector becomes
broken due to an accident, etc., repair or replace it.Negative(-)

General Information - Repair Instruction1-103.Precautions for Use of Jack and Safety Stand
(1)always use the wheel stoppers when performing servicing on
level ground.
(2)use safety stand and rubber support as shown in the illustration.
(3)use the jack and safety stand to support specified location.
(4)When jacking up the front wheels of the vehicle, release the
park brake and place stoppers only behind the rear wheels. When
jacking up the rear wheels, place stoppers only before the front wheels.
(5)During the job, make sure to use safety stand instead of jack
only to support the vehicle.
(6)When only jacking up the front wheels or rear wheels, place
stoppers before or after the wheels touching the ground.
(7)when lowering the vehicle with its front wheels lifted, release
the park brake, and place the stopper only before the rear wheels.
When lowering the vehicle with its rear wheels lifted, place the stop-
per only after the front wheels. the opening of the removed inlet system parts and the engine with a
clean shop lag or gum tape.
(3)When installing the inlet system parts, check that there is no
mixing of a metal scrap.
5. Handling of Hose Clamp
(1)Before removing the hose, check the clamp position to re-tighten
it for sure.
(2)Replace a deformed or dented clamp with a new one.
(3)In case of reusing the hose, install the clamp on the hose where
it has a clamp track.
(4)For a steel band circlip, make it adjust by adding force to the
arrow mark direction after the installation.II. Vehicle Lift and Support Location1. Vehicle Conditions To Be Under Attention During Lift
(1)Generally speaking, when being lifted, the vehicle should be empty, do not lift the heavily loaded vehicles.
(2)When removing heavy parts such as engine and transmission, the center of gravity of the vehicle will move.
Place balance weight to prevent the vehicle from rolling or use special jack to support the vehicle.
2. Precautions for Use of Four-tappet Lift
(1)follow the safe operation instruction described in this manual.
(2)do not damage the tire or rim.
(3)use wheel stopper to retain the vehicle.Rubber SuportSteel Band Circlip
