GENERAL INFORMATION

The cooling system is designed to keep every part
of the engine at appropriate temperature in
whatever condition the engine may be operated.
The cooling method is of the water-cooled, pressure
forced circulation type in which the water pump
pressurizes coolant and circulates it throughout the
engine. If the coolant temperature exceeds the
prescribed temperature, the thermostat opens to
circulate the coolant through the radiator as well
so that the heat absorbed by the coolant may be
radiated into the air.
The water pump is of the centrifugal type and is
driven by the timing belt or drive belt from the
crankshaft.
The radiator is the corrugated fin, down flow type
and is cooled by the electrical radiator fan.
The cooling fans are controlled by a fan controller
and the engine-ECU depending on driving
conditions.
