2001 Mercury Cougar V6 6 Cyl 2.50L

Preventive Maintenance

A loud intermittent humming sound - seems to come from fan area.

The sound happens when I take my foot off the gas, or intermittently while sitting at an idle. As soon as I press the gas pedal it goes away. It's a sound that goes up and down, sounds kind of like an loud low-pitch kind of hum or echo. Someone looked at it and said it could be the fan or a belt, but no one seems to be able to pin down what it is. thank you for any assistance you can offer.

Sounds like it could be the fan from your description. Can you disconnect the fan and see if the noise goes away?
