COOLING FAN COMPONENT CONSTRUCTION/OPERATION [L8, LF]

id0112b4141900

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

Item | Specification

Cooling fan | Number of blades | 5
Outer diameter | (mm {in}) | 360 {14.2}
Cooling fan motor output | (W) | 120

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 ELECTRICAL FAN CONTROL OUTLINE [L8, LF].)
• The cooling fan may keep operating for a few seconds or minutes after the ignition switch is turned off depending on the engine coolant temperature. (See ELECTRICAL FAN CONTROL OUTLINE [L8, LF].)
