Fan clutch can cause that as well, the type that needs air pressure to release. I'd isolate it and see if that solves the problem. It's hard to diagnose otherwise because you can't hear the leak with the engine running and the clutch stays engaged with the engine off. I noticed it when I had someone shut the engine down and heard a brief sssst at the fan when it engaged.
