(3) Cautions before service
Prolonged exposure to the engine oil make cause a skin cancer or an irritation.
Used engine cotains the hazardous material that may cause the skin cancer. Do not allow the used
engine to make contact with your skin.
Make sure to wear the protection gloves and goggle when handling the engine oil. If contact
happens, rinse affected areas immediately with plenty of water. Do not wash it with gasoline or
solvent. If irritation persists, consult a doctor.
Improperly disposed engine oil can pollute the environment. Dispose used engine oil in accordance
with local environmental regulations. -

(5) Tightening the fastener
If fine dust or foreign material enters into DI engine's fuel system, there can be serious damages
between HP pump and injectors. So, be sure to cover removed fuel system components with cap
and protect removed parts not to be contaminated with dirt. (Refer to cleanness in this manual
while working on DI engine fuel system)
When working on the fuel line between priming pump and injector (including return line), always
plug the openings with caps to prevent foreign materials or dust from entering to the openings and
connections.
The HP fuel supply pipe (HP pump to fuel rail) and HP fuel pipe (Fuel rail to injector) should be
replaced with new ones when removed. 1.
2.
3. Scalding hot coolant and steam could be blown out under pressure, which could cause serious injury.
Never remove the coolant reservoir cap when the engine and radiator are hot.
(4) Lubrication system
3) Fuel and Oil System
If work on the fluid system such as fuel and oil, working area should be well ventilated and smoking
should be prohibited.
Gasket or seal on the fuel/lubrication system should be replaced with new ones and bolts and nuts
should be tightened as specified. -
-Clean the mating surfaces before tightening.
Place the marks with paint to tighten by angle if the angle wrench is not available. 1.

4. CHECK AND INSPECTION
1) Cylinder
(1) Compression pressure test
Specified value ▶
Compression ratio16.5 : 1
Test conditionat normal operating temperature (80˚C)
Compression
pressureStandard32 bar
Minimum18 bar
Differential limit between cylindersMaximum 3 bar
The compression pressure test is to check the conditions of internal components (piston, piston ring,
intake and exhaust vale, cylinder head gasket). This test provides current engine operating status.
Measurement ▶
Warm the engine up to normal operating temperature (80°C).
Disconnect the fuel rail pressure sensor connector to cut off the fuel injection.
Remove the air cleaner duct and glow plugs. -
-
-
Place the diagram sheet to compression
pressure tester and install it into the plug
hole. 1. Before cranking the engine, make sure that the test wiring, tools and persons are keeping away
from moving components of engine (e.g., belt and cooling fan).
Park the vehicle on the level ground and apply the parking brake.
Do not allow anybody to be in front of the vehicle. -

Plug the removed components with clean and undamaged sealing caps and store it into the box to
keep the conditions when it was installed. 6.
Fuel filter assembly
Follow the job procedures. If you find a defective component, replace it with new one. 5.
Once disconnected, the fuel pipes between HP pump and fuel rail and between fuel rail and each
injector should be replaced with new ones. The pipes should be tightened tospecified tightening
torques during installation. Over or under torques out of specified range may cause damages and
leaks at connections. Once installed, the pipes have been deformed according to the force during
installation, therefore they are not reusable. The copper washer on injector should be replaced with
new one. The injector holder bolt should be tightened to specified tightening torque as well. If not, the
injection point may be deviated from correct position, and it may cause engine disorder.
To supply the fuel to transfer line of HP
pump press the priming pump until it
becomes hard. 7.
Priming pump
Check the installed components again and connect the negative battery cable. Start the engine and
check the operating status.
With Scan Tool, check if there are current faults and erase the history faults. 8.

How To Use Pressure Tester ▶
Press the "TEST" button on the tester to
check if the message "TEST?" is displayed.
If the button is pressed again at 4 seconds
after starting engine cranking, the highest
pressure is displayed on the tester. 1.
2.
The fuel rail pressure value can be checked using a diagnostic device.

03-172210-01
HP pump pressure test ▶
Prepare a special tool for high pressure test
and clean it thoroughly to prevent foreign
materials from entering. 1.
Disconnect the high pressure fuel supply pipe
on the HP pump and install the close rail in the
tool kit. 2.
Connect the other end of the close rail to the
fuel rail for test. 3.
Disconnect the return hose for HP pump and
connect the clear hose and connect its the
other end to the return port of the fuel rail for
test. 4.
Connect the digital tester connector to the
sensor connector of the fuel rail for test.
Crank the engine 2 times for 5 seconds after
removing the IMV connector and fuel rail
pressure sensor connector.
Read the pressure value displayed on the
tester display is within the specified. 5.

1. OVERVIEW
The components in fuel system supply the fuel and generate the high pressure to inject the fuel to
each injector. They are controlled by the engine ECU.
The common rail fuel injection system consists of fuel tank, fuel line, low pressure line which supplies
low pressure fuel to the low pressure pump (including high pressure pump), common rail which
distributes and accumulates the high pressurized fuel from the fuel pump, high pressure line which
connected to the injector, and the engine control unit (ECU) which calculates the accelerator pedal
position and controls the overall performance of vehicle based on the input signals from various
sensors.
