temporary "humming noise"

Discussion in '2002 - 2005 Ford Thunderbird' started by MarkW, Nov 11, 2017.

  1. After 2004 t bird is warm, there is a hum that is emmitted from the engine compart......seeems to cease after a few minutes....any advice?
  2. A little more info - where does the hum seem to come from - if you can open the hood and pin point the sound by listening closely, also are there any vibrations or changes in engine idle/performance that accompany the hum?
  3. thnx for reply..I did notice it runs hotter, then drops back when "humm" ceases.......
  4. Sounds like the electric fan motor for the radiator
