i have no visual leaks and i have replaced my water pump and radiator cap, along with new coolant my car keeps buzzing very loud like the little speaker is going to blow

 

Try the 2nd generation section.

 

If your coolant level is fine in the filler neck and it keeps beeping, your coolant level sensor might be shorted. I had a similar situation where the cord going to the coolant level sensor was disconnected and caused the same thing to happen.
