Electrical equipment ▶
Electric devices should be handled more carefully.
Currently, the engine has a lot of electric devices. there could be poor engine performance,
incomplete combustion and other abnormal symptoms due to short circuit or poor contact.
Before work on engine and each electrical equipment, be sure to disconnect battery negative
(-) terminal.
When replacing the electric device, use only genuine part and check the conditions of
connections and grounds. Loosened connection or ground make cause a fire and personal
injury. -
-Fuel and lubrication system ▶
Do not allow the fluid and engine oil to make contact with the body paintwork and hoses.
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.
After removal/installation works, be sure to check whether there is leak on the connecting
section. -

If fine dust or foreign material enters into DI engine's fuel system, there can be serious damages
in HP pump and injectors. Thus, be sure to plug the inlets of removed fuel line 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)

The strut type tensioner automatically adjusts the belt tension to provide the reliability and
durability for the system. And, the belt tension is decreased to minimize the friction loss and
improve the belt operating noise.

2) Belt Tensioner
(1) Overview
The torque deviation from crankshaft affects the components in belt drive system and the belt
movement. The auto tensioner system is to adjust this deviation automatically.
In D20DTR engine, one of the mechanical tensioner, pivot damped tensioner is used to keep the
damping force, system reliability and durability. The single belt drive system needs to use the
automatic belt tensioning device to transfer the power to pulleys effectively. To get this, the
tensioner uses the spring and damping unit.

Vacuum pump
Pump capacity: 210 cc/rev
Camshaft speed:
375 to 3,000 rpm
Lubrication temperature:
-40 to 155°C
Oil: 5W30
Drive type: Driven by exhaust
Camshaft sprocket
EGR cooler bypass valve
This valve is controlled by ECU. When the
engine is cooled, the exhaust gas goes to
combustion chamber without passing through
EGR cooler because the valve is closed by
vacuum pressure.
2. VACUUM PUMP
Vacuum pump generates the vacuum pressure and supplies it to EGR cooler bypass solenoid.
This pump is single vane type and displacement is 210 cc/rev. The lubrication oil is supplied
through the hole in hollow shaft.
