Pontiac G5 Radiator Fan Assembly

An engine produces vast amounts of heat as it continuously burning fuel in its confined combustion chambers. This makes it one of the greatest challenges for car owners to prevent the engine from overheating. A significant factor in keeping a car engine cool is the engine's cooling fan assembly. The most powerful fan assemblies are supported by a mounting cover, fan-blade, and engine all form the part of the engine cooling system. This works as the heat from the engine's coolant is transferred by supplying the radiator with enough air.

The radiator fan assembly allows for the cooling of the engine. These cooling radiator fans are particularly helpful if the vehicle is moving very slowly and you are stuck to the outside airflow and air can not pass over the grill. Depending on the vehicle's internal temperature, the electrical cooling radiator fan which switches on and off as required is an improvement over motor-driven fans which slows down as much as required.

When the thermostat opens, the coolant on the engine is pumped into the radiator and a series of coils are sent to cool the coolant. The radiator uses the airflow to cool the radiator coils, and if it reaches some point the radiator fan can increase the airflow. This cycle stops the car from being overheated the entire time that the engine is running.

Normally, a cooling fan assembly is mounted between the radiator and the engine. This can be mounted on the radiator or behind it. Especially important for modern vehicles with small grill dimensions is airflow in the radiator. The cooling fans are powered by either an electric motor or the crankshaft of an engine.
