COOLING FAN COMPONENT CONSTRUCTION/OPERATION [L8, LF, L5]

id0112g1141900


Construction

Note
•  There are four types of cooling fan components, A, B, C, and D. Types A, B, C, and D can be identified from the number of blades and fan motor connector terminals on the cooling fans No. 1 and No. 2.
•  The cooling fan component consists of the radiator cowling, cooling fans, cooling fan motors, and coolant reserve tank.
•  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.
•  Coolant reserve tank can be removed from the radiator cowling.
