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
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.
(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. -
-
(3) Cautions before service
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
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
Clean the mating surfaces before tightening.
Place the marks with paint to tighten by angle if the angle wrench is not available. -
-
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. -
-
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.
