Engine Cooling System: General Description: Notes

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 aluminum radiator fins are used.
• The speed of the fan motor is controlled by a fan control module. The engine control module (ECM) <M/T> or powertrain control module (PCM) <A/T> detects driving conditions and controls the controller so that the fan operating noise is minimized and fuel efficiency is improved <3.8L Engine>.
