4. CAUTION WHEN SERVICING THE ENGINE
1) Cleaness
Engine has a lot of precisely machined (grinding, polishing, lapping) surfaces. Thus, there should
be great cautions for cleaness when servicing the engine components. Apply the engine oil on the
sliding surfaces when assemblying the components. Every component should be disassembled
and reassembled in accordance with the correct sequences. Before servicing the engine, the
negative cable should be diconnected from the battery. Otherwise, some electric or electronic
components could be damaged.
2) Servicing
(1) Lifting up the vehicle
Always keep the safety precautions.
To prevent the vehicle from rolling down, put the chocks under the tires (when using a 4-post
lift).
Make sure to support the correct lifting points (when using a 2-post lift) -
-
-
(2) Exhaust system
Wear the safety glove when removing the exhaust pipe.
Make sure that the exhaust pipe is cooled before removing it. -
-Before service work, be sure to disconnect battery negative (-) terminal to prevent damages
by bad wire and short.
To prevent the foreign material from getting into engine cylinder, cover the inlet of air cleaner
if the air cleaner has been removed -

(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. -

5. STANDARD BOLTS SPECIFICATIONS
Metric bolt strength is embossed on the head of each bolt. The strength of bolt can be
classified as 4T, 7T, 8.8T, 10.9T, 11T and 12.9T in general.
Observe standard tightening torque during bolt tightening works and can adjust torque to be
proper within 15 % if necessary. Try not to over max. allowable tightening torque if not required
to do so.
Determine extra proper tightening torque if tightens with washer or packing.
If tightens bolts on the below materials, be sure to determine the proper torque. 1)
2)
3)
4)
Aluminum alloy: Tighten to 80 % of above torque table.
Plastics: Tighten to 20 % of above torque table. -
