The cooling system is a water-cooled pressurized, forced circulation type
which offers the following features.
- To stabilize engine coolant temperature, the thermostat is located at the coolant inlet port from the radiator.
- To improve engine cooling performance and save weight, a plastic tank and aluminium radiator fins are used.
- The speed of the radiator fan is controlled by a fan controller. The engine-A/T-ECU detects driving conditions and controls the controller so that the fan operating noise is minimized and fuel efficiency is improved.
