Small circulation: when coolant temperature is below 82 ± 2°C, the thermostat closes. Coolant only circulates 
inside the cylinder block, and warms up other engine parts where need heat. Water pump assembly circulates 
the engine coolant through cylinder block, electronic throttle assembly, oil cooler assembly and cylinder head. 
The coolant does not radiate heat through the radiator.
Large circulation: when coolant temperature is higher than 103 ± 1°C, the thermostat opens fully, and all the 
coolant, which flows out of cylinder block, enters the radiator where coolant heat is lost. The heat-radiated 
coolant returns to the cylinder block for circulation by water pump. Due to the heat lost in radiator, the engine 
coolant temperature drops quickly to prevent engine from overheating.
For CVT model, coolant will enter the transmission oil cooler assembly under the large circulation, so that the 
temperature of transmission oil in transmission decreases.
When engine operates properly, the cooling fan operates under the following conditions:
a. If engine coolant temperature sensor malfunctions, the cooling fan remains rotate when engine operates 

properly;

b. When A/C compressor is operating, the cooling fan operates at low speed.
c. When A/C compressor is operating and receives request signal from the A/C pressure switch, the cooling 

fan operates at high speed.

d. When coolant temperature is higher than 96°C, the cooling fan starts to operate at low speed;
e. When coolant temperature is higher than 102°C, the cooling fan starts to operate at high speed;
f. When coolant temperature is below 99°C, the cooling fan stops at high speed;
g. When coolant temperature is below 93°C, the cooling fan stops at low speed.
