Kia Cadenza: Cooling System / Cooling Fan Description and Operation
[Air conditioning type]
The cooling fan operates in 2 stages (HIGH/LOW). The engine
control module (ECM) controls the cooling fan according to the coolant
temperature, vehicle speed and A/C operation.

The cooling fan operates in 1 stages (HIGH). The engine
control module (ECM) controls the cooling fan according to the coolant
temperature, vehicle speed and A/C operation.
