my 05 is leaking coolant at the water pump. It's not coming from the gasket between the case and the pump but from the little hole that is in the bottom of the pump cover. does anyone know what that means? bad pump? replace the impellar? it's dripping at a decent pace...not shooting out but about a drip every 5 seconds. I didn't search the forums since i am in kinda a hurry....sorry. Thanks!
