engine GEELY FC 2008 Workshop Manual

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.

Engine control systemEFI systemOn-vehicle inspection1. Inspection of the voltage of power steering oil pres-
sure sensorMeasure the voltage between PS terminal and E2 terminal
with ohmmeter2. Inspection of stepping motor(a) With engine running at idle speed, pull out the connection harness of stepping motor, and the change
of engine rotating speed indicates that the stepping motor operates normally.
(b) Pull out the connection harness of stepping motor, and measure the terminal current with universal
meter. When engine is running, there being impulse current output at the terminal indicates that there
is no trouble with ECU and stepping motor control system, and if idling is not stable at the moment
and deviates greatly from specified value, the stepping motor should be replaced. If there is no
impulse current output at the terminal, turn on air conditioner to test again, and still no impulse
current output indicates that there is trouble with ECU and stepping motor control system circuit.
(c) Check the malfunction of stepping motor circuit with diagnostic instrument.Engine control system·- EFI system 8Conditions Voltage (V) Not turning steering wheel with

Engine control system·- EFI systemInspection1. VVT control solenoid valve assembly (4G18-1006200)(a) Resistance inspection
(1) Measure the resistance between terminals with ohmmeter
Resistance: (b) Operation inspection
Connect battery positive (+) wire to No.1 terminal and negative (-) wire to No. 2 terminal, and check
valve operation.
Note: ensure that the valve is not stuck.
Hint: if there are foreign matters in the valve, the valve could not be closed tightly and will
thus result in slight pressure being lifted toward higher direction.2. Throttle body components (4G18-1001240)(a) Inspection of throttle body
(1) Throttle valve shaft should not swing.
(2) All channels should not be blocked.
(3) Throttle valve plate should rotate flexibly and act smoothly.
(4) When the throttle is at closed position, there should be no clearance between throttle stop bolts and
throttle lever.
Note: it is not allowed to adjust the throttle stop bolts.3. Throttle position sensor (4G18-3600080)(a) Resistance inspection
(1) Remove the wiring harness connectors of throttle posi-
tion sensor.
(2) Measure the resistance between 1# pin and 2# pin with
ohmmeter, resistance value: .
(3) Connect 2 terminals respectively to 1# pin and 3# pin,
and turn the throttle, the resistance value varies linearly
with the opening of throttle, but 2# pin and 3# pin are
contrary to this.
Note:pay attention whether there is great jump with
resistance value when observing resistance change. 9
