COOLING FAN COMPONENT CONSTRUCTION/OPERATION [13B-MSP]
id0112f2141900
Construction
• The cooling fan component consists of the radiator cowling, cooling fans, and cooling fan motors.
• Electric cooling fans No.1 and No.2, which operate according to the fan control signal from the PCM, have been adopted. Due to this, engine noise has been reduced and rapid engine warming-up is possible.
• The radiator cowling and cooling fans are made of plastic for weight reduction.

Operation
• Cooling fans No.1 and No.2 operate 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
STARTER CUT-OFF CONTROL OUTLINE [13B-MSP].)
