Engine whine/whistle in the morning when cold.
 

2006 4.4i 65k miles.
In the morning, especially that now the temp is lower there is a strong engine noise. when the car warms up after about 15 minutes of driving it goes away. Recently it has gotten louder.
Has anyone experienced this?

Thanks for the help.

Could be pulley or belts...get a diagnosis.

Here's a possible reason/solution (new post)
