The Infiniti cooling fan is an essential part of the engine cooling system, helping to provide a flow of cool air into the engine compartment to keep the engine safe from overheating. The engine cooling system requires a constant flow of air through the radiator to assist in the engine cooling process, used to dissipate the heat gathered by the liquid coolant as it travels through the engine to lower engine temperature. The momentum of the vehicle as it travels at normal driving speeds will generate enough airflow into the engine compartment to maintain a safe operating temperature for the engine. However, when the vehicle is idling or traveling at slow speeds the assistance of the Infiniti cooling fan is needed to draw air in through the radiator. The Infiniti cooling fan is powered with an electric motor in most late model vehicles and front wheel drive vehicles. The electric Infiniti cooling fan uses a thermostatic switch to rotate the fan blade only when the temperature in the engine compartment rises to a level that indicates the need of its assistance to prevent overheating, conserving power when it is not needed. In some older model vehicles, the Infiniti cooling fan is operated by a belt and pulley system, drawing the power to rotate its blade directly from the engine. Many of these belt driven Infiniti cooling fan systems use a fan clutch to produce a variable speed for the fan blade, slowing the rotation when its use is unnecessary.
