2008 GEELY MK transmission

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
the preparers and tight schedule are encouraged and pled to contact Geely International in time for
our timely correction of the mistakes.ForewordGeely International Corporation

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

inspect for leaks. Check if there is oil/water marks at static joints,
or if there is oil/water drops dripping down at dynamic joints
10min after the vehicle is stopped, there is a leak; if there is oil/
water marks/drops, but it does not drip down, there is seepage.Measure the temperature of transmission oil inspection hole.
Usually it is not higher than ambient temperature.
Check the surface temperature of wheel trim column. Usually
it is no higher than ambient temperature.

a circle with same steering wheel angle, and accelerate from
low to high speed, the diameter of the circle increases gradually.

2-9 c. Check levels of braking fluid, engine coolant, engine oil, transmission oil, power steering fluid, and
washing fluid to see if there is any leaking.
d. Inspect if brake pedal, clutch pedal, accelerator pedal, transmission shifter, steering wheel, choke are
loose or stuck. The free travel of clutch pedal is 5~15mm, the free travel of brake pedal is 1~6mm and
the free play of steering wheel is less than 30mm(measurement point at margin of steering wheel). if it
is out of this normal range, the clutch needs to be tuned.
e. Inspect if the connection of battery, lamps and signal lights are normal, and if the wire routing and
position are correct and not loose.
f. Inspect if the tire pressure is correct.
(2) On-road inspection If the inspection result of the above items is good, start the engine and test the car on
road, and perform the following inspections.
a. Acceleration pedal, see if the operation is smooth and if it is loose.
b. Clutch, see if there is any stuck or abnormal noise, and slip when driving.
c. Transmission,check if shifting is smooth,or rough and wrong shifting.Inspect if the display of A/T
shift lever is normal.
d. Steering, check if steering is light and smooth, and if the steering wheel turns back after steering.
e. Brake pedal, apply brake pedal to check if the braking functions well when vehicle speed is at
40km/h and if the vehicle runs off track.
f. Park brake, when parking brake handler is pulled, there should be 6~9 clicking sounds. Pull park brake
when vehicle is running at the speed of 20km/h and transmission is at neutral gear to see if it brakes.
g. Vehicle speed meter, observe the vehicle speed meter while driving. When speed changes, check if the
indicator is moving steadily or shakes.
h. Heating and air-conditioning.Try every control button to see if both heating and cooling system work
well.
i. Abnormal noise, listen carefully to see if there is any abnormal noise from engine, drive line system or
any other parts of the vehicle at a steady speed and during accelerating, and decelerating.
(3) Inspection after test ride check if there is anything abnormal in the vehicle while driving and conduct the
following inspections after the vehicle is parked.
a. Check electrical fan When engine coolant temperature is beyond 92.5°C, the radiator fan should be
running; When A/C is on and the pressure of refrigerant is more than 1.5 cooling ton, air conditioning
cooling fan should be running.
b. Check headlamp, method: park the car 5m away from the inspection surface (inspection board, curtain,
or wall) to the front bumper, and check if the beam from headlamp is good. The upper level if headlamp
should be 540mm above the ground, and the distance between headlamps on the two sides is 900mm.
c. Inspect engine idle speed,idle speed of hot engine is 800r/min±50r/min,when A/C compressor works,
the idle speed should be 900r/min±50r/min. If idle speed is abnormal, adjust the idle speed adjust
ment screw to adjust it.
(4) Usage of new cars in breaking-in period Follow the instructions below in the first 1500~2500km breaking
mileage to avoid wear and abnormal damage in breaking-in period, and to improve vehicle performance, fuel
economy and to extend vehicle useful life.
a. Drive steadily during breaking-in; do not accelerate harshly to avoid running engine at high speed.
Engine should not exceed 4500r/min in any gears. Especially at the early stage of breaking-in, vehicleUsage and Maintenance of MK Series - Usage of MK Series
