There's no quick fix. The leak is coming from a shaft seal in the water pump, and that one's not replaceable without some hydraulic press work. Even then, I believe the bearing/seal assembly is scarce and expensive, if it's available at all. Sometimes a seep leak will fix itself with a little run time and a few heat/cool cycles, but a gusher is a different kettle of fish!
