ENGINE COOLING –

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 <GDI> or drive belt <MPI>
from the crankshaft.
The radiator is the corrugated fin, down flow type
and is cooled by the electrical radiator fan.
For vehicles with GDI, the cooling fans are controlled
by a fan controller and the engine-ECU depending
on driving conditions.
For vehicles with MPI, the cooling fan is controlled
by the engine-ECU in accordance with the engine
running condition.
