Re: humming sound (maxnix)
The problem is individual discriptions of sounds in writing vary. Is the whistle like a train or boat whistle, a dog whistle or a human whisting.How long does it last in seconds [exact please], does intensity or pitch vary.
Most people are not trained experienced NOVELIST and may not select the the EXACT appropriate paragraph to fully describe a Sound so that the reader can perfectly duplicate it in their mind.
Why not provide a link to an actual recording?

Re: humming sound (Q45tech)
My wild azz guess is he is hearing a squealing belt or failing idler pully bearing........or sleeping cat getting tangled in fan?
Re: humming sound (qship96)
maybe an armadillo in the fan
ok well i am a novice with this car.. so thx for the advice on posting.. yes the sound is like a train. it does it only right when started in really cold weather..the sound would be on maybe 5 seconds then will go off then sometimes comes back on sometimes doesnt.. i took a look today and it seemed like it was coming possibly from fan?? is there a pully on it or somethin that could go? pitch is lower with no change in pitch.. thank you
Re: (TmaCular)
I already told you what the problem is in my first post in this thread.

Re: (TmaCular)
I really do think it's an idler pulley bearing. They tend to lock for a few seconds during cold startup, causing a few seconds of a screech. Then you'll get several minutes of a howl that sounds just like a Ford power steering pump... That howl would change with the idle speed though.TmaCular wrote:not really definately not a cat... or a belt or pully..any otha ideas
A mechanic's stethoscope should help you narrow it down. http://www.harborfreight.com/c...41966

Re: (TmaCular)
try shaking the fan blade when the engine is off to see if there is any play in the clutch, the noise might be coming from the fan clutch
Re: (TmaCular)
also check the water pump. it sits behind the fan and is on the front of the engine, the noise could be transmitting to the fan
