2008 GEELY FC engine

Preface
Geely “FC” is an automobile with high performance/price ratio and it meets the requirement
of national safety, energy saving, emission regulations and personal use. This automobile is
a completely new and excellent model produced by Zhejiang Geely Automobile Co., Ltd with
development in self-reliance of Geely group and with self-dominated intellectual property
right. It characterizes elegant appearance,
energy conservation and environmental protection,
safety and comfort. “FC” is a product opening a completely new viewpoint of automobile
selection, because it is developed on the basis of creative design thinking that breaks through
all established customs and it features perfectly balanced performance of power, space,
safety, manipulation and comfort. “FC” is a competitive product for Geely developing brand
and exploring mid-level automobile market, which takes over the company philosophy “make
good cars that common people can afford, and let Geely cars go to the whole world” of Geely
automobile. “FC” is combination of creativity and intelligence of quite a large number of
automobile experts, who have been developing and searching with great concentration for
more than 30 months, and it fully embodies persistent Geely style of fashion appearance
and high performance/price ratio.
“FC” is equipped with engine JL4G18 completely developed and produced by Geely group.
Engine JL4G18 applies the following advanced technology such as VVT, full aluminum cylin-
der body, plastic intake manifold, completely new VVT inside seal method, completely new
OCV valve filtering method etc. with M7.9.7 electric injection system of BOSCH, and its
index on power efficiency, economical efficiency, and safety efficiency etc. reaches leading
level of national model with the same type. This engine features strong power, low fuel
consumption, low noise and high power per liter etc.
We start to compile “FC” Automobile Maintenance Manual, which is divided into 27 sec-
tions with detailed description of overall structure and maintenance of engine 4G18.VVT;
inspection and repair of engine BOSCH M7.9.7 electric control fuel injection system; struc-
ture and maintenance of chassis; structure and maintenance of FC electrical equipment;
structure and maintenance of ABS anti-lock brake system; structure and maintenance of
SRS air bag; structure and maintenance of auto air conditioning system; structure and main-
tenance of vehicle body etc. Information is detailed and accurate, contents are in systematic
coherence and description is concise and comprehensive.
This manual is compiled from structure, which prompts “FC” service personnel to master

necessary maintenance, repair and malfunction knowledge on the basis of understanding
main structure characteristics and simple principle of vision automobile. Electric control sys-
tem of “FC” automobile is particularly described with detail, and detailed steps and methods
are given for trouble shooting process. All kinds of malfunction could be eliminated quickly
and efficiently within the shortest time as long as you detect as the repair steps of this manual.
In addition, this manual is compiled with the following characteristics: in proper sequence,
clear demarcations, easy to understand, excellent in picture and its accompanying essay,
simple and clear, which is very applicable for a quite large number of “FC” automobile main-
tenance technicians and service personnel to refer to.
This manual is mainly compiled by Geely International Corporation; Geely Automobile En-
gine No. 2 Plant and engineering technicians of service corporation help complete this work.
Defects and mistakes are inevitable in this manual for limited level of compiler and limited
time, please contact Geely International Corporation if you find mistakes and careless omis-
sions in using and we can correct in time and reverse in next version.
