Weird buzzing noise upon cold start...
My truck has a erratic, buzzing sound coming from the front, passenger side area of the engine bay. It is louder when the truck is first started and is cold. The last few days its been 3-6 degrees below zero out and the truck has the "buzzing" noise which is pretty loud.
It disappears when the truck is up to operating temps and it is not there during the summer when it's warm.
The noise is coming from the area of the belts between the engine and the fan. I have a video of the noise so I'll try and figure out how to upload it.
