2. MAINTENANCE
1) Level Check
Park the vehicle on a level ground and apply the parking brake. Stop the engine and wait more
than 5 minutes.
Pull out the dipstick and wipe it with a clean cloth. Reinsert it all the way.
Pull out it again and check the oil level.
The oil level should be between the maximum (Max) mark and minimum (Min) mark on the oil
dipstick. Oil should be replenished before the level goes below the minimum mark. -
-
-
Operating vehicle with insufficient amount of oil can damage the engine. Make sure the engine
oil level is correct and add oil if necessary.
2) Replenishment
If the level gets to the lower point, open the filler cap on top of the cylinder block and add the
genuine oil without exceeding the level of the upper mark.
Recheck the oil level after 5 minutes.
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.
The oil should not go above the upper mark on the dipstick.
The engine oil may be consumed more if the engine is new. -

1. SYSTEM DESCRIPTION
1) Overview
The lubrication system supplies oil to each lubrication section to prevent friction and wear and to
remove heat from the friction part. As the engine runs, frictional heat is generated on each
lubrication section. If this condition persists, the bearing can be burned and stuck.
In other words, it creates an oil film on each sliding surface to convert solid friction to liquid
friction in order to minimize wear and prevent temperature increasing on the friction part.
For the D20DTF engine with no oil pressure switch, the engine ECU receives the low engine oil
level signal from the oil level sensor and communicates with the instrument cluster through the
CAN communication to turn on the warning lamp.

1) Coolant Level Check
Park the vehicle on level ground and apply the parking brake. Stop the engine and wait until it is
cooled down.
The coolant level should be between the MAX and MIN mark on the coolant reservoir.
Check the coolant level. If the level is below the “MIN” mark, immediately add coolant. 1.
2.
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.
Avoid any direct contact of the coolant to the painted body of the vehicle. -

3. CAUTIONS
If 100% of anti-freeze is added, the water pump vane can be damaged and thermal
conductivity can be decreased resulting in poor circulation in the cooling system which leads
to overheated engine.
Use of non-recommended coolant could cause damage to the cooling system and
overheating of the engine.
Opening the coolant reservoir cap while the engine is running or hot can cause burns by hot
steam or water.
To open the coolant reservoir cap, wrap the cap with a wet towel or thick cloth after the
engine is cooled down sufficiently.
If cool water is added to the heated engine, the engine or radiator can be deformed.
The anti-freeze in the coolant can damage the painted surface, so avoid the contact of the
coolant to the painted body.
The anti-freeze and water should be mixed in proper mixture ratio. Never add only water
when adding coolant.
If the anti-freeze content is too low, the coolant can be frozen while the engine can be
overheated if anti-freeze content is too high. -

Oil filter module
Thermostat
When the engine coolant
reaches 90℃, the thermostat
starts to open (fully open at
100℃) and lets the coolant
flow to the radiator to
maintain the engine
temperature.
Water pump
The water pump is driven by the engine drive belt and
supplies the coolant to each area of the engine.
Coolant reservoir
Long life coolant is used.

Electric fan
Circulates the fresh air forcibly to exchange
heat with the radiator core fin.
Radiator
Releases heat through fins and cools down the hot
coolant as the coolant passes through the tube of
the radiator core.
Coolant temperature sensor
Measures the coolant
temperature and sends the
result to the engine ECU.

Disconnect the cable connected to the
B terminal on the alternator. Connect
one end of the ammeter to the B
terminal and the other end to the cable
connected to the B terminal.
Measure the maximum output value.
(Maintain the engine speed between
2,500 and 3,000 rpm.)
(Turn the headlamp and all the electrical
switches on.) 1.
2.Pass: If the measured current is
45 A or higher.
Fail: If the measured current is
less than 45 A.
Check the current of the B
terminal. -

Move the gear selector lever to the
neutral position.
Maintain the engine speed at 2,500 rpm
with the vehicle unloaded.
(Turn all the electrical switches off.) 1.
2.Open circuit: If the measured
current is 5 A or higher. -
Disconnect the negative cable from the
battery.
Remove the B terminal and turn off the
ignition switch.
Measure the resistance between the L
and F terminals with an ohmmeter. 1.

3.Pass: If the measured resistance
is between 3 and 6 Ω.
Faulty rotor coil or slip ring: If the
measured resistance is less than
3 Ω or greater than 6 Ω. -

Alternator
The alternator charges the battery and
supplies power to each electric unit by
converting the mechanical energy to the
electrical energy.
1. SYSTEM DESCRIPTION
1) Overview
The charge system is designed to supply electrical energy to the vehicle while driving, and
supplies a constant direct current voltage by converting mechanical rotational movement to
electrical energy.
The voltage regulator on the back of the alternator controls the generated voltage in all rotating
ranges and adjusts the system voltage according to the electric load and ambient temperature
change.
2) System Layout (Locations)
Battery
It converts the chemical energy to the
electrical energy and supplies power to
the corresponding electric units when
starting the engine.
