COOLING SYSTEM

14-2

GENERAL DESCRIPTION

M1141000100360

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 circu-
lation type in which the water pump pressurizes cool-
ant and circulates it throughout the engine. If the
coolant temperature exceeds the prescribed temper-
ature, 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 drive belt from the crankshaft. The radi-
ator is the corrugated fin, down flow type and is
cooled by an electrical radiator fan. And if the engine
coolant temperature reaches 110

°C (230°F) or

higher, the radiator fan control rotates the radiator
fan for up to 5 minutes even after the ignition switch
is turned to the "LOCK" (OFF) position [the fan stops
its rotation when the engine coolant temperature
decreases to 110

°C (230°F) or lower].
