Hello,

This could be leak from the water pump. There could be a seal that is leaking when cold but as it warms up and expands the leak stops.
You might want to do a pressure test of the cooling system to see if you can verify the leak. On a pressure test the cooling system is given pressure that simulates the pressure at engine operating temperature. This makes any more easily detectible.
You can get those testers at your local auto parts store to rent.

Here is a helpful video:

On this vehicle in order to replace the pump, the timing belt needs to be removed. It is recommended to change the timing belt if you are changing the water pump and vice versa.
