INFINITI QX56 noisy radiator auxiliary fan possibly due to bad bearings on INFINITI QX56

Some INFINITI QX56 owners report experiencing issues with a noisy radiator auxiliary fan, which may be caused by bad bearings within the fan assembly. Common problems reported include the radiator fan not working due to issues with the fan assembly, fan clutch, or coolant temperature sensor. Additionally, a loud clicking noise on startup could indicate problems with the coolant temperature sensor or cooling fan relays. For those bothered by the radiator fan noise, expert mechanics provide useful tips for diagnosing and fixing the issue. Some owners also report a roaring noise from the engine cooling fan assembly, often accompanied by inadequate air conditioning performance, which may necessitate replacing the engine cooling fan assembly and the IPDM E/R. Regular maintenance and prompt repairs are recommended to ensure the optimal performance of the vehicle's cooling system.
