3. ENGINE COMPARTMENT LAYOUT
Do not work on the engine compartment while the engine, radiator, exhaust manifold, muffler or
catalytic converter is hot. Always turn the engine off and allow it to cool before starting the
maintenance.
Regularly check the engine oil level and add Ssangyong genuine engine oil if necessary.
Clean the dipstick with clean cloth so that any foreign materials cannot get into the engine. -

3. 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.
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. -

4. GUIDELINES ON ENGINE SERVICE
To prevent personal injuries and vehicle damages that can be caused by mistakes during engine and
unit inspection/repair and to secure optimum engine performance and safety after service works, basic
cautions and service work guidelines that can be easily forgotten during engine service works are
described in.
Cautions before service works
For safe and correct works, you must observe the working procedures and instructions in this
manual. And, use the designated tools as follow:
Engine stand / Heavy duty engine jack
To prevent the engine from starting abruptly, do not allow anybody to get in the vehicle while
servicing in engine compartment.
Before work on engine and each electrical equipment, be sure to disconnect battery negative (-)
terminal.
Before service works, be sure to prepare the works by cleaning and aligning work areas.
Do not allow the foreign material get into the fuel injection system.
When removing the engine, use only the safety hook on engine and engine hanger. Do not support
the bottom of oil pan with a jack.

▶
Completely drain the engine oil, coolant and fuel from engine before removal.
Before disassembling/assembling the engine components, carefully read the working procedures in
this manual.
Make sure to keep the specified tightening torques during installation.
Clean and properly lubricate the parts before reassembly.
Carefully check that there are not any interference while servicing. -

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)

1) Chain Drive
(1) Overview
The drive chain is single chain drive system with simple design and variable performance, and it utilizes
the hydraulic tensioner to reduce the wave impact generated by the chain\
. This chain is light weight and
has high durability through single bush chain. Shoulder bolts are used f\
or better NVH.
7. CHAIN AND GEAR DRIVE SYSTEM
D20DTR engine uses single stage chain drive system. Timing chain drives the exhaust side and gear
drive the intake side. Timing chain is single bush ty pe. Upper chain drives HP pump connected to intake
Camshaft by driving exhaust camshaft sprocket, and lowe r chain drives oil pump to lubricate the engine.

(2) Tensioner
Tensioner adjusts the chain tension to keep it tight during engine running. This reduces the wear in
guide rail and spoke.
Operating principle
- Use the spring tension in tensioner and hydraulic pressure
Tensioner type
- Compensation and impact absorbing

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.
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.
To supply the fuel to transfer line of HP pump
press the priming pump until it becomes
hard. 7.

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.

2) Diagnostic Test for Engine Fuel System
(1) Overview
If a DTC is displayed on the diagnostic device, check the low pressure- and high pressure fuel systems
before removing the components.
To run the system properly, the electric system must be intact but for the DI engine, the fuel pressure
should be measured also when there is a malfunction even after the diagnostic test with a diagnostic
device.
