To check if your water pump is leaking you can place a piece of paper or cardboard under your vehicle overnight and check in the morning for any liquid on the paper. If so, you may have a faulty water pump. You can also gently rock the water pump pulley back and forth to see if it has any give. If so, it is most likely the bearings are going and you will need to replace the water pump. You can also inspect the water pump for any noticeable leaks or cracks.
