Why Do Original Radiator Fan Assemblies Fail?
Radiator cooling fans fail for a number of reasons, all stemming from the heat and stress they endure while trying to cool an engine. Bearings can melt from high temperatures, fan blades can break, sensors can fail, and mechanical pieces can stop working over time.
When radiator fans don't work correctly, the radiator can't serve its purpose to keep the engine cool. When an engine overheats, it can cause a number of problems, and make the vehicle inoperable altogether. That's why replacing a broken radiator fan should be an immediate priority.
