id011219141900
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.
• Coolant reserve tank can be removed from the radiator cowling.
