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

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 mechanismEngine assemblyInspection1. Check coolant.
2. Check engine oil.
3. Check battery.
4. Check air filter assembly.
5. Check spark plug [4G18-3705113].
6. Check drive belt [4G18-1307107].Hint: do not check belt tension, because automatic tensioner is applied.7. Check ignition timing.(a) Warm up engine.
(b) Connect timing lamp to engine.
(c) Check ignition timing at idle speed.
Ignition timing: before top dead center Note: when checking ignition timing, place
transmission at neutral position.
Hint: After run the engine for 5 seconds with rotating
speed of 1000-1300rpm, check the engine could
recover to idle running.8. Check engine idle speed.(a) Warm up engine and run it at idle speed.
(b) Read engine rotating number in data flow with diagnostic instrument.
(c) Check idle speed.
Idle speed: about 750-850rpm
Notes:When checking idle speed, place cooling fan at OFF position.Turn off all auxiliary devices and air conditioner.Engine mechanism - Engine assemblyK-line 26
Engine mechanism - CamshaftWarning: if the air pressure in timing advance side oil duct is released earlier than that in
timing delay side oil duct, VVT driver assembly will move suddenly toward
delay side.This will cause the damage of lock pin.
(g) Remove VVT drive fixed bolts.
Notes:
It is strictly forbidden to remove other 4 bolts.
Under the condition of repeating using camshaft
timing sprocket, release lock pin at first, and then
install sprocket.12. Install VVT driver assembly.
13. Install camshaft.Put VVT driver assembly together with intake camshaft.
(a) As shown in the diagram, gently make VVT assembly
hold camshaft and turn it toward left until straight pin is
inserted into groove.
Warning: it is strictly forbidden to turn camshaft
timing sprocket toward timing delay side
(toward right).
(b) Check there is no clearance between sprocket flange
and camshaft.
(c) Fix camshaft timing sprocket and then tighten flange
bolt.
Torque: 70 ±5N.m
(d) Check VVT driver assembly could move to timing
delay side and is locked at max. timing delay position.
(f) As shown in the diagram, align alignment mark with
timing mark on camshaft timing sprocket, and install
timing chain on the timing sprocket.
(g) Check forward mark and figure, and tighten bolts as
sequences shown in the diagram.
Torque: 13 ±0.78N.m
(h) Align alignment mark on the chain with timing mark on
camshaft timing sprocket, and place exhaust camshaft
in cylinder head.Straight pin

then connect 2 terminals respectively to 1# pin and 3# pin of sensor, and ensure the voltage is 12V.
(b) Start engine, and phase signal is read by 2# pin via vehicle oscilloscope.2. Speed Sensor(a) Remove speed sensor joint.
(b) Place digital universal meter at ohm gear, and connect 2 terminals respectively to 2# pin and 3# pin of
sensor, and the resistance at should be 8601/2 ±801/2.
(c) Connect speed sensor joint.
(d) Place digital universal meter at AC voltage gear, and connect 2 terminals respectively to 2# pin and 3#pin of sensor, and start engine, there should be voltage output at the moment.(It is recommended to
check with vehicle oscilloscope)IgnitionIgnition systemInspection1. Spark plug(a) Clean spark plug.
Air pressure: below 588kPa.
Time: 20 s or less
(b) Check the damage condition of spark plug and insulator. If
there is something abnormal, please replace with new spark
plug.
