5. RECOMMENDED FLUIDS AND LUBRICANTS
- Use only Ssangyong recommended fluids and lubricants.
- Keep the specified levels when adding or replacing the fluids.
- Do not mix any different types or brands of oils or fluids. This may cause damages.

(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.

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.

5. CYLINDER HEAD COVER AND OIL SEPARATOR
The cylinder head cover is made by high strength plastic to reduce the weight. The multi twist type
oil separator improves the oil consumption.

Location of Expansion Plugs
1) Cylinder Head
(1) Overview
The cylinder is made by gravity casting and the water jacket is integrated type.
The cylinder oil passage is drilled and sealed by cap.
The Camshaft bearing cap is also made by casting and installed on the cylinder head.

Intake/Exhaust Camshafts
2) Camshaft
(1) Overview
Hollow type camshaft contains cam, octagon cam, HP pump gear and intake/exhaust gears.
Camshaft operates the intake/exhaust valves, vacuum pump and HP pump, and transfers the
engine oil to vacuum pump through the internal oil passage.

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 for better NHV.
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 type. Upper chain drives HP pump
connected to intake Camshaft by driving exhaust cam shift sprocke, and lower chain drives oil
pump to lubricate the engine.
