COOLING SYSTEM
The cooling system is a water-cooled pressurized, forced circulation type which offers the following features.
D
To improve the reliability of cavitation at a high engine speed and to increase the amount of engine
coolant, output control system in which a thermostat is installed at the outlet of engine coolant from
the engine to the radiator has been adopted.
D
To improve the engine cooling performance and save weight, a plastic tank and an aluminium radiator
fins have been introduced.
D
The speed of electric cooling fan is optimally controlled by a radiator fan controller and the engine-ECU
according to driving conditions so that the fan operating noise is minimized and the fuel efficiency
is improved.
