COOLING FAN COMPONENT CONSTRUCTION/OPERATION [LF]
E5U011215140N01
Construction
• The cooling fan component consists of the radiator cowling, cooling fan, and cooling fan motor.
• Electric cooling fan, which operates according to the fan control signal from the PCM, has been adopted. Due
to this, engine noise has been reduced and rapid engine warming-up is possible.
• The radiator cowling and cooling fan are made of plastic for weight reduction.
Cooling fan, cooling fan motor specification
Operation
• Cooling fan operates according to the engine coolant temperature and whether the A/C is on or off. Three-
stage control has been adopted to the cooling fan with high, middle, and low speed rotation allowing noise
reduction and power savings. (See 01–40–34 ELECTRICAL FAN CONTROL OPERATION [LF].)
