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

Starting and Charging System-
Starting System5-23. WiringII. Starter assembly replacement (MR479Q, MR479QA, MR481QA)1. Remove starter assembly
(1) Disconnect starter connector.
(2) Remove nuts, disconnect starter cable.
(3) Remove 2 bolts and starter assembly.
2. Install starter assembly
Installation should be conducted in reversed direction of removal
Torque:
Bolt 37N.m
Wire harness 9. 8N.m (1) Check that connecting wire between positive pole of storage battery and starter must be firm and reliable,
outside shroud must be in good condition, so as to prevent generating electric spark and causing fire.
(2) Check whether wire is conducted, whether sheath is broken, if wiring harness is damaged, replace wiring
harness.Please Refer to "MK WIRING DIAGRAM"
