fuel filter GEELY MK 2008 Workshop Manual

2-11a. Keep air filter clean, Block of air filter affects engine air induction efficiency and increases fuel
consumption. So it must be cleaned and replaced in time.
b. Keep ignition system under good work condition. Bad connection or electricity leak of ignition coil and
power distributor or inappropriate gap or carbon residue of spark plug decreases ignition power supply
and efficiency, which leads to engine fuel consumption increase. So they need regular inspection and
repair to keep their good work condition.
c. Fuel feeding system works well. Often check if fuel feeder pipe leaks, and check if injectors and other
parts perform well on regular basis (electrical injection engines).
d. Keep regular tire pressure. If the tire pressure is not enough, vehicle rolling resistance increases and
engine fuel consumption increases accordingly. So tire pressure must be checked on time (around once
a week).Usage and Maintenance of MK Series - Usage of MK Series

2-12Section 2 Maintenance Category and Content of MK SedanAs the vehicle is being used, its technical performance changes as the mileage accumulates and being affected by
various factors, which results in decrease of power, fuel economy, safety, and increase of emission pollutions,
noise and incidents. So timely maintenance during vehicle usage eliminates potential risks and prevents incidents
from happening, improves vehicle integrity and technical functionality, and prolongs useful life of the vehicle.
According to the vehicle technical requirements and usage history, maintenance of freedom Cruiser sedan can be
classified into several categories.I. first time maintenanceFirst time maintenance is also called breaking-in maintenance. It is performed when the vehicle mileage has
accumulated to 1500~2500km in breaking-in period. First time maintenance must be conducted at the appointed
service shops. It includes:
1. Check if there is any leak in engine, transmission, and differential. Fix if there is any.
2. Replace engine oil filter, engine oil and ATF for A/T.
3. Check the level of engine coolant, braking fluid, windshield washing fluid, power steering fluid and if there
is any leak. Refill if the level is too low and repair if there is any leak.
4. Check if there is any damage in triangle arm and ball joint, connection ball joint, triangle arm flexible hinge,
or the ball joint is loose. If there is, fix or replace it.
5. Check if the drive shaft dust cover is damaged. If there is, replace it.
6. Check if there is any leak in steering mechanism, or front and rear absorber and fix it there is any.
7. Check the tire pressure, front 230kpa, and rear 210kpa.II. Regular maintenanceAfter first time maintenance, the vehicle is in regular usage life. During regular use, the vehicle needs to be
maintained regularly according to the way it is used in.
1.Regular maintenance for vehicles used under extreme bad conditions. Any of the condition below is defined
as extreme bad condition:
(1) Frequent start.

2-18Section 3 Daily Maintenance of MK SedanDaily maintenance means operation of vehicle regular inspection, cleaning, fastening, and refilling according to
vehicle usage and condition on the basis of regular maintenance to make sure the vehicle is at good status. Daily
maintenance can be performed by driver or professional automotive mechanics in daily use of vehicle. But some
of the items must be conducted by professional mechanics at service shops.
1. Maintenance of air cleaner
Air cleaner filters the air that is coming into engine for the first time. Dust and other dirt filtered out gathers in the
induction tube. Air cleaner filters a lot of dust and dirty, so it must be cleaned in time.
2. Maintenance of air filter
Air filter does not only filter the dust and dirt in the air, but also keeps smooth ventilation. Its status has great effects
on the fuel economy and power of the engine, so it must be checked and maintained in time.
Before it is time to replace air filter, maintain it. Remove the filter, knock it with hand or stick to get rid of dust
on the filter and remove dirt inside the filter cover according to the cleanness of the road that the vehicle usually
runs on.
ATTENTION: do not clean the filter with wet cloth. Fasten the filter well when installing it back.
3. Maintenance of battery
Battery is used to start the vehicle and supply power to electrical facilities. Its status directly affects the regular
usage of the vehicle, especially for vehicles equipped with electrical controlled facilities. Keeping the battery in
good technical status and connections is especially important. It is necessary to often perform the following
inspections and maintenance in regular usage:
(1) Clean the outside of battery Inspect if the battery case or cover surface is dirty or has dirt, oil, or other dirty
things regularly. Clean it and keep the surface dry to avoid electrical leak caused by cover deformation.
(2) Check battery connections Bad connection between battery electrode and cable results in low engine start
speed which makes it difficult to start the vehicle or the vehicle cannot be started because of low output voltage
from battery. Loose connection at battery end leads to damage of electrical components and loss of trouble code
and other information stored in RAM of the computer system as a result of low voltage. Therefore, it is necessary
to check if the connection of cables on the battery electrode is good. When it is found loose, it must be fastened.
If there is any rust, the cables must be loosened, washed clean and be connected again.
4. Maintenance of tires and wheels
(1) Keeping tires and wheels under good condition is very important to vehicle fuel consumption and driving
safety. Therefore, inspect and maintain the tires regularly. Every 10000 km, the wheels should be adjusted. Follow
the sequence in picture 3:
Judge if there is any hidden problems in vehicle chassis mechanism by observing wear in different places, andfinding out the hidden problems does not only help you to understand
the technical status of the vehicle, but also benefits driving safety.
a. Serious wear on both edges of tire tread, means tires often
work with low tire pressure.
b. Wear of middle of the tire tread is mainly because the tires
are used with high tire pressure.This kind of wear shortens
the useful life of tires, and may result in sudden flat tire
when the vehicle runs on uneven road surface or meets any
obstacles.Usage and Maintenance of MK Series - Daily Maintenance of MK Sedan

Chapter 3 Fuel SystemSection 1 Check Fuel System PressureOn-board inspection
1. Check the operation of the fuel pump.
(1) Connect the positive and the negative of the battery to
appropriate connector sockets of the fuel pump (see Figure 3-1).
Attention: Do not start the engine.
If there is pressure present, you will hear that the fuel is flowing.
If there is no pressure present, check the fusible cutout, fuse, EFI
open-circuit relay, fuel pump, ECM (Electronic Control Module) and
circuit joint.
(2) Turn the ignition switch to "OFF".
2. Check the pressure of the fuel.
(1) Check whether the battery voltage is more than 12V.
(2) Disconnect the negative wiring cable from the battery.
(3) Mount a pressure gauge on the fuel input pipe
(see Figure 3-2).
(4) Connect the negative terminal of the battery.
(5) Measure the fuel pressure.
Fuel oil pressure: 265-304kPa
If the pressure is low, check the fuel pipe and connection,
fuel pump, and fuel filter. If the pressure is too high,
replace the regulator.
(6) Start the engine. Measure the fuel pressure at idle speed. The
fuel pressure is 265-304KPa. If the pressure is unsatisfactory, checkFigure 3-1
Figure 3-3 Figure 3-2Fuel SystemCheck Fuel System Pressure3-15the fuel pump, pressure regulator, and injector, and replace if necessary.
(7) After shutting down the engine, check the fuel pressure and
keep the specified pressure for about 5 minutes. The fuel pressure is:
147KPa.
3. The fuel oil pressure regulator (DR) (see Figure 3-3).
Mounting position: On the distributing pipe for fuel.
Faults: Too low or too high fuel pressure, or hard to start.
General causes: Using poor fuel for a long time results in: 1.
strainer blocked; 2. serious leakage caused by particles and impurities.
Other reasons: Man-made mechanical damage, etc.
Maintenance precautions: During maintenance: 1. Never impact the diaphragm element with high pressure
gas; 2. Never clean it with aggressively corrosive liquid; 3. No distortion caused by external force.
Easy measuring method: For the system with oil return, connect a pressure gauge for the fuel on the suction
pipe, start the engine, and run at idle speed. Now, the fuel pressure in the engine should be about 260KPa; pull out
the vacuum pipe of the fuel pressure regulator, and the pressure should be 300KPa approximately.Battery

Symptom
Poor idle speed, malfunction etc
Symptom
Fail to start5-125 Repair precautions:
1. according to engine requirement, electric fuel pumps with different flows are available, they have the same
appearance, mountable fuel pump may not be exactly suitable, during repair, part number of fuel pump used must
be consistent with original one, wrong replacement is not permitted;
2. in order to prevent fuel pump from damaging, please do not run it in dry state for a long time;
3. in case fuel pump needs to be replaced, please pay attention to clean fuel tank and pipeline and replace fuel
filter.
(2) Simple measuring method:
(Remove joint) turn digital multimeter to ohm position, connect two meter pens with fuel pump pins
respectively, measure internal resistance, it should not be zero or infinite (namely not in short circuit, open circuit
condition).
(Connect joint) connect fuel pressure gauge on sucker, start up engine, run the engine at idle speed, now fuel
pressure of engine should be about 260kPa; unplug fuel pressure regulator vacuum tube, now fuel pressure should
be about 300KPa.
11. Canister control valve
(1) Canister in fuel evaporation control system adsorbs oil vapor from oil tank until saturated. Electronic
control unit controls opening of canister control valve, fresh air and saturated fuel vapor in canister form
regeneration stream, which is led into engine intake pipe again. Electronic control unit changes duty ratio of pulsing
signal to canister control valve solenoid according to different operating conditions of engine, thus controls flow
of regeneration stream. In addition, this flow is also influenced by pressure difference at both ends.
Possible cause
Entering of foreign matter into valve inside results in
corrosion or poor leak tightness etc
Repair precautions:
1. To install, airflow direction must meet the specification;
2. when black granules inside valve body result in malfunction of control valve, and control valve needs to be
replaced, please check the condition of canister;
3. avoid water, oil etc liquids from entering valve as far as possible during repair;
4. in order to avoid transfer of solid-borne noise, it is recommended to install canister control valve suspending
on the hose or use soft rubber to fix.
(2) Simple measuring method:
(Remove joint) turn digital multimeter to ohm position, connect two meter pens with canister control valve pins
respectively, rated resistance at 20°C is 22 - 30 ohm.
12. Ignition coil
(1) When earthing channel of primary winding is connected, this primary winding is charged. Once ECU cut
off primary winding circuit, charging stops, high voltage is induced in secondary winding at the same time, so spark
plug discharges. Ignition coil ZSK 22 (both ends of 2 secondary windings are connected with a spark plug
respectively, so these two spark plugs ignite simultaneously.
Possible cause
Too heavy current leads to burnout, damaged by external force Repair precautions: it is prohibited to use "short circuit ignition testing method" to test ignition function, soEngine EFI System-
