SYSTEM DESCRIPTION

COMPONENT PARTS

Radiator

INFOID:0000000012197546

• A side flow radiator with an aluminum radiator core and plastic tank

is adopted.

Cooling Fan

INFOID:0000000012197547

• A cooling fan with plastic shroud is adopted.

• The cooling fan is controlled by the ECM (engine control module)

based on the vehicle speed, coolant temperature, and A/C signals.

• For details about the control, refer to 

EC-646, "COOLING FAN

CONTROL : System Description"

.

Water Pump

INFOID:0000000012197548

• The water pump adopts an outer bearing type pump.

• The water pump is driven by the drive belt. For the drive belt path, refer to 

EM-186, "Inspection"

Multi-way Control Valve

INFOID:0000000012197549

A motor-driven valve that integrates the thermostat and water control

valve and that can open and close the flow of water to the heater, oil

cooler, and radiator according to the coolant temperature is adopted.

• When the water temperature is low, the water channels to the

heater, oil cooler, and radiator are closed, accelerating warming of these parts.

• After they are warmed up, the radiator water channel is opened and closed to control the hot water tempera-

ture (100 to 105 

°C), raising the engine oil temperature for reducing friction and improving fuel economy.

For control, refer to 

EC-647, "THERMAL MANAGEMENT CONTROL : System Description"

DESCRIPTION

Engine Cooling System

INFOID:0000000012197550

• The radiator adopts a side flow aluminum radiator core.

• A drive belt is adopted for water pump operation.

• A multi-way control valve is adopted to control the water temperature.

• A shallow bottom is adopted for the cylinder block water jacket for optimizing cooling performance.

• An electric cooling fan is adopted. The cooling fan is controlled by signals from the ECM (engine control

module).
