2013 SSANGYONG KORANDO engine coolant

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 o
r
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. -

Water pump
The water pump is driven by the engine drive belt and supplies
the coolant to each area of the engine.
Coolant reservoir
Thermostat
When the engine coolant
starts to open (fully open at
flow to the radiator to maintain
the engine temperature.
1. OVERVIEW
The coolant system is to keep the engine temperature stable.
2. COMPONENTS

2112-01
Coolant temperature
sensor
Measures the coolant
temperature and sends the result
to the engine ECU.
Radiator
Radiates the heat through fins and cools
down the hot coolant as the coolant
passes through the tube of the radiator
core.PWM fan
Circulates the fresh air forcibly to exchange
heat with the radiator core fin.
Coolant outlet port
