Cooling System: Description and Operation

GENERAL DESCRIPTION

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].
