Re: What have I done? Video attached: Bad sound after oil change on ol' Blue

That does sound like the fan intermittently hitting something. Can you grab the fan blades and wiggle them a little, after shutting the engine off, of course? Maybe your water pump bearing is going out, looks like there is a little drip of something on the crossmember under the fan.
