Will water leak out of a water pump bad enough to make a good size puddle if the car isn't running? There is coolant leaking from the water pump and I parked the car next to the garage. I haven't driven it for a few days and when I went out there, there was a good size puddle. I plan on putting on a new water pump, but want to make sure that there isn't something else that could be bad. I don't see anything sign of a hose leaking. When I grab them the seem good and don't leak. But the fluid is under the car more toward the oil pan. It is forsure coolant. Must just be seaping back there. The water pump is in the front passenger side of the car.
