(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.

(2) Cylinder pressure leakage test
If the measured value of the compression pressure test is not within the specifications, perform
the cylinder pressure leakage test.Specified value ▶
Perform this test in the sequence of firing order.
Do not test the cylinder pressure leakage with wet type test procedure. (do not inject the
engine oil into the combustion chamber) -
-
Test condition: normal engine operating
temperature (80˚C)Specified value
Whole engine below 25%
at valve and cylinder head gasket below 10%
at piston ring below 20%
Crank the engine for approx. 10 seconds
by using the start motor. 2.
Record the test result and measure the
compression pressure of other cylinders
with same manner. 3.
If the measured value is out of specified
value, perform the cylinder pressure
leakage test. 4.
