Nissan Pathfinder engine fan failure due to bad bearings, requires replacement on Nissan Pathfinder

Some Nissan Pathfinder owners report experiencing engine fan failures due to bad bearings, which can lead to noise and overheating. This issue is particularly common in models from 2013 to 2020, where worn fan motor bushings may cause the fan blade to wobble and hit the fan shroud, resulting in additional noise problems. Owners have noted that an overheated engine can lead to significant mechanical failures, making it crucial to address radiator fan issues promptly. The radiator fan is essential for preventing engine overheating and avoiding costly damage, and if the fan stops working, the engine temperature can rise rapidly, potentially resulting in engine failure if not resolved quickly. Therefore, replacing the fan unit is often necessary to maintain optimal engine performance and longevity.
