Cooling System: Description and Operation

^ The engine cooling system consists of a down - flow radiator which features high heat - dissipation performance, an electric motor fan, a water pump, a thermostat, and an engine coolant temperature sensor.

^ The reserve tank is designed to eliminate the need for replenishing coolant.

^ On models without an air conditioner, the ECM sends an ON or OFF switch signal to the radiator fan in response to signals from the engine coolant temperature sensor. On models with an air conditioner, the ECM sends ON or OFF switch signals to the radiator main fan and sub fan in response to signals from the engine coolant temperature sensor, vehicle speed sensor 2 and A/C switch.
