So a couple days ago I turned on my car and I heard this whistling noise after about twenty minutes of that I noticed that my coolant was leaking and I got to see that it was leaking from the belt side. Right underneath the alternator I have not moved the car since. Any suggestions?

I would suggest borrowing a cooling system pressure tester from the local auto parts store (AutoZone, Advance Auto, Oreilly) and hooking it up to the radiator. Basically, you will pump up the pressure and then look around to see where it is leaking from. From your description, it sounds like you have a pinhole sized leak in a cooling system hose that is connected to the water pump or the water pump itself is leaking. The pressure tester will help you to diagnose where it is coming from. I am including a link to our guide on running that pressure test. https://www.2carpros.com/articles/radiator-pressure-test

If you want, you can take pictures of the leaking part and we will help you identify what it is and help you fix it. Good luck and keep us posted.
