Is it a fast leak or a slow leak? The best way to troubleshoot this is to fill the tank again and try to see where the coolant is leaking from. If you can't see the exact place where it is leaking, try to find the area where it is leaking. This way you will know if it is the water pump or a hose. You may even just have a loose hose.
