I just replaced my belts and idle/tensioner pullies to find out that my water pump is the one that was makes grinding noise. Obviosly I want to replace it.

My questions are:

1. How much of coolant do I have to let out and how do I do this?
2. My dad mentioned something about being careful of air getting into the cooling system! ?? anyone know if I should be worried about this?

Btw, here's the video of my water pump

P.S. It wasn't like this prior to belt change. I would notice it if it was like this before.
