It has been noted that the Mercedes Benz has a mean engine, with top speeds of 300km/h that could only be a walk in the park on the Autobahn. But in the heat of things, it must be cooled down at times. Just like the engine, it must have an efficient cooling system to prevent overheating. Factors to be considered are the coolant and the radiator.
The coolant absorbs the heat form the engine, while the radiator dissipates heat. But the catalyst would be the radiator fan, for without it the radiator won't perform as it is design to do. Then, a malfunctioning cooling system will trigger a chain reaction of damage to the engine caused by overheating.
Also referred to as a condenser fan or the automotive fan, the radiator fan draws air outside to the radiator, which makes the radiator have an easier time to dissipate heat. Usually, more than one fan is mounted in the vehicle, with the fan installed just behind the radiator. Additional electric fans are mounted to cool the A/C condenser and other engine and A/C parts.
