worn pully bearing

I'm finally getting annoyed with this endless chirping from my truck. A pully bearing just above the crank is dry and chirping, especially in the wet weather. Problem is my truck is kinda tall and I can't easily make out what it is or drives. Could someone show a belt diagram with all the pulleys around the crank named so I know how what to repair. I just managed to hit it with a little oil and the chirping stopped for a while, so I'm sure I found it but can't make out its purpose.

It's a 2008 3.0l

Thanks

Just above the crank would be the belt tensioner pulley . The entire assembly is removed by one bolt , NOT the bolt in the center of the pulley itself.
Take note of the position of the locator stud on the back when you remove it.

On my engine the tensioner is above the crank to the right, right above the crank is a larger pulley almost the same diameter as the crank pulley and I can see that its probably the coolant pump. I can just see hoses leading into a housing just behind it when I really crawl up in there. Are these pumps serviceable?
