  • Hi Bill.

    You mention the fans are noisy, they should run smoothly, so they might be bad, or it could something else.

    Have you checked for any related DTCs?

    1. Check the thermostat for proper operation
    2. Check the coolant system making sure there are no leaks, and no radiator restrictions. To free your radiator of restrictions:
      • clean the outside of the radiator to ensure unrestricted air flow
      • clean the interior of the radiator so it will not have deposits which restrict the flow of coolant.
    3. Check the cooling fan system:
      • the coolant temperature sensor
      • the fan relay
      • the fans
