Coolant is leaking from somewhere behind the beauty covers that shroud my pulleys, ( crank pully, water pump pully. Etc.). But there isn't any water leaks on the top side of my motor.( Hoses are fine. Thermastat isn't leaking. Etc.) Could this be my water pump? It doesn't leak right away. Only when the coolant cap is on. And its warmed up. I take the coolant cap off. And it quits?

Probably is a water pump leak, the engine covers will have to be removed and the system pressure tested to find out for sure.
