Thread: does fan ever operate

  1. #11
    The service manual for my 07 says the fan will come on at 428 degrees and go off at 356 degrees with the key on. with the key off the fan will operate at 338 degrees and go off at 302 degrees. Yes i did dictate that correctly.

    Ya I think it must be reading cylinder temperature because I'm pretty sure that oil breaks down quickly at above 300. either that or its a typo in the manual

    So the fan is controlled by the ECM? If so, can its on/off temps be modified with ECMspy?
