3) General Instructions
Before lifting up the vehicle with a lift, correctly support the lifting points.
When using a jack, park the vehicle on a level ground and place the wheel chocks under the tires.
Position the jack under the frame and lift up the vehicle and then support with chassis stand before
service work.
Make sure to disconnect the negative (-) cable from the battery to prevent any damage to electric
systems.
If you have to work on vehicle, cover the seats and floor with protection covers to avoid any
damage and contamination.
Brake fluid and anti-freeze can damage the painted surface of body. So carefully handle them
during service work.
To improve the efficiency of service work, use only recommended and specified tools.
Use only Ssangyong genuine spare parts.
Never reuse the cotter pin, gasket, O-ring, oil seal, lock washer and self-locking nut. Replace them
with new ones. If reused, normal functions cannot be maintained.
Store the disassembled parts as a set based on disassembly order and unit.
Pay particular attention not to miss or mix the fasteners.
If necessary, especially for inspection, clean the removed parts completely.
Apply the oil or grease on the running and sliding surfeces before installation. Use the specified
sealant and gasket to prevent leakage if necessary.
Tighten the fasteners with the specified tightening torque.
As a final stage of service work, check if the serviced system is working properly and the problem
has been eliminated clearly. (1)

4) Basic Inspection
(1) Horn operation
Listen for the horn sound when pressing the horn pad on the steering wheel. -
(2) Brake operation
Check if there is any abnormal noise, unusually long braking distance, or uneven braking force. If the
brake warning lamp does not go out even after starting the engien or are flashing during driving,
have the brake system checked immediately.
Check the brake pipes and hoses for connection, oil leak, crack or interference after changing the
position of tires. When replacing the tires, check the brake disc for surface condition and wear.
Check the parking brake cable and brake operation. Shorten the checking interval if the parking
brake is used frequently. -
-
-
(3) Exhaust system
Be aware to any changes in sound or smell from the exhaust system. These may be caused by leak or
overheat. Have the exhaust system checked and repaired immediately.
Inspect the exhaust system including catalytic converter. Inspect all the components and body frame
near the exhaust system. -
-
(4) Tires
Unusual vibration of the steering wheel and seats or pulling to one side on the straight and level roads
may indicates the uneven tire inflation pressure or poor wheel balance. -
(5) Steering and suspension system
Inspect the front and rear suspension and the steering system for damage, looseness or missing
parts, signs of wear or lack of lubrication. Inspect the power steering line and the hoses for
connection, leak, crack and chafing. Inspect the drive axle boot and seals for damage, tear or leak.
Replace or repair the system if necessary. -
(6) Engine oil
Check the oil level when the engine is still warm and add the specified engine oil if necessary. -
(7) Coolant
Check the coolant level in the coolant reservoir, coolant conditions (contamination, foreign material),
and hoses for damage and leak. Replace or add the Ssangyong genuine coolant, if needed. -
(8) Engine drive belt
Check all drive belts on the engine for wear, crack and looseness. Retighten or replace the belt, if
needed. -

10. FLYWHEEL AND DRIVE PLATE
1) DMF (Dual Mass Flywheel)
The dual mass flywheel, or DMF, eliminates excessive transmission gear rattle, reduces gear
change/shift effort, and increases fuel economy. There is a friction ring located between the inner and
outer flywheel that allows the inner and outer flywheel to slip. This feature is designed to alleviate any
damage to the transmission when torque loads exceed the vehicle rating of the transmission. The friction
ring is the weak spot in the system and can wear out if excessive engine torque loads are applied
through it. The system also has a center support bearing that carries the load between the inner and
outer flywheel, and is fitted with damper springs to absorb shocks.
2) Drive Plate
Drive plate receives the power from the start motor when starting the engine. With this, the drive plate
initially drives the power train system. And, it is connected to the torque converter to transfer the engine
torque to the power train system.Components

2) Inspection of Turbocharger
On-board Inspection 1.
Check the bolts and nuts foe looseness or missing
Check the intake and exhaust manifold for looseness or damage
Check the oil supply pipe and drain pipe for damages
Check the housing for crack and deterioration -
-
-
-
Inspection of turbine 2.
Remove the exhaust pipe at the opening of the turbine and check, with a lamp, the existence of
interference of housing and wheel, oil leakage and contamination (at blade edge) of foreign
materials.
Interference: In case where the oil leak sign exists, even the small traces of interferences on the
turbine wheel mean, most of times, that abrasion has occurred on the journal bearing. Must
inspect after overhauling the turbocharger.
Oil Leakage: Followings are the reasons for oil leakage condition -
-
Problems in engine: In case where the oil is smeared on inner wall section of the exhaust gas
opening.
Problems in turbocharger: In case where the oil is smeared on only at the exhaust gas
outlet section. *
* When problem occurs with the turbocharger, it could cause engine power decline,
excessive discharge of exhaust gas, outbreak of abnormal noise and excessive
consumption of oil.
Idling for long period of time can cause oil leakage to the turbine side due to low pressure of
exhaust gas and the rotation speed of turbine wheel. Please note this is not a turbocharger
problem.
Oil Drain Pipe Defect
In case where oil flow from the turbocharger sensor housing to the crank case is not smooth would
become the reason for leakage as oil builds up within the center housing. Also, oil thickens (sludge)
at high temperature and becomes the indirect reason of wheel hub section. In such case, clogging
and damage of the oil drain pipe and the pressure of blow-by gas within the crank case must be
inspected.
Damages due to Foreign Materials
When the foreign materials get into the system, it could induce inner damage as rotating balance of
the turbocharger gets out of alignment. -
-

3) Inspection of Turbine
Thoroughly check the followings.
Interference: In case where is trace of interference or smallest damage on the compressor wheel
means, most of times, that abrasion has occurred on the journal bearing. Must inspect after the
overhaul.
Oil Leakage: The reason for oil leakage at the compressor section is the air cleaner, clogged by
substances such as dust, causes the compressor inlet negative pressure. -
-
Rotating in high speed at no-load for extended period of time can cause oil leakage to the
compressor section as oil pressure within the center housing gets higher than pressure within the
compressor housing.
Overuse of engine break (especially in low gear) in down hill makes significantly low exhaust gas
energy compared to the time where great amount of air is required during idling conditions of the
engine. Therefore, amount of air in the compressor inlet increases but the turbocharge pressure
is not high, which makes negative pressure at the compressor section causing the oilleakage
within the center housing. a.
b.
No problem will occur with the turbocharger if above conditions are found in early stage but oil
leaked over long period of time will solidify at each section causing to breakout secondary
defects.
Damages by foreign materials: In case where the compressor wheel is damaged by foreign materials
requires having an overhaul. At this time, it's necessary to check whether the foreign materials have
contaminated intake/exhaust manifold or inside of engine.
Must absolutely not operate the turbocharger with the compressor outlet and inlet opened
as it could damage the turbocharger or be hazardous during inspection.

3. TROUBLESHOOTING
The followings are cautions to take in handling defects of turbocharger, which must be fully aware of.
1) Cautions
After stopping the engine, check whether the bolts on pipe connecting section are
loose as well as the connecting condition of vacuum port and modulator, which is
connected to the actuator.
During idling of the engine, check for leakage in the connecting section of pipe (hoses
and pipes, duct connections, after the turbocharger) by applying soap water. The
leakage condition in the engine block and turbine housing opening can be determined
by the occurrence of abnormal noise of exhaust.
By running the engine at idle speed, abnormal vibration and noise can be checked.
Immediately stop the engine when abnormal vibration and noise is detected and make
thorough inspection whether the turbocharger shaft wheel has any damages as well as
checking the condition of connections between pipes.
In case where the noise of engine is louder than usual, there is possibility of dampness
in the areas related with air cleaner and engine or engine block and turbocharger. And
it could affect the smooth supply of engine oil and discharge.
Check for damp condition in exhaust gas when there is sign of thermal discoloration or
discharge of carbon in connecting area of the duct.
When the engine rotates or in case where there is change in noise level, check for
clogging of air cleaner or air cleaner duct or if there is any significant amount of dust in
the compressor housing.
During the inspection of center housing, inspect inside of the housing by removing the
oil drain pipe to check for sludge generation and its attachment condition at shaft area
or turbine side.
Inspect or replace the air cleaner when the compressor wheel is damaged by inflow of
foreign materials.
Inspect both side of the turbocharger wheel after removing inlet and outlet pipe of the
turbocharger.
- Is the rotation smooth when the rotor is rotated by hand?
- Is the movement of bearing normal?
- Inspect whether there has been any signs of interference between two wheels. 1.

Basic principle at low speed
At low speed, it utilizes the principle of venturi. For
example, when air flows through the venturi tube,
the flow speed is faster and the pressure is lower
at the point "A". In this case, if the inner diameter
of venturi is more narrowed, the flow speed is so
much faster (refer to the equation).

4. OPERATING PRINCIPLES
The E-VGT is designed to get more improved engine power in all ranges by controlling the turbine as
follows:
1) How it Works at Low Speed
Normal turbocharger cannot get the turbo effect because the amount of exhaust gas is not enough and
the flow speed is slow in a low speed zone, but VGT allows the flow passage of exhaust to narrow,
resulting in increasing the flow speed of exhaust gas and running the turbine quickly and powerfully.
Therefore, as VGT can intake more air than normal turbocharger, it can give the benefit of the increased
output even in a low speed zone.
Turbocharger lag
The turbocharger is at idle speed when there is no load or it is in the normal driving condition. During
this period, the amount of exhaust gas passing through the turbine is not enough to turn the
compressor wheel (impeller) fast. Therefore, the intake air is not compressed as needed.
Because of this, it takes time for turbocharger to supply the additional power after the accelerator
pedal is depressed. This is called "turbocharger lag".
