Water pump shaf

t is a little wet, is it flinging coolant up on top?

 

Can't really tell with that pic but...If it's the water pump shaft leaking it's time to replace it..The thermostat housing isn't the leaker right ??? And sometimes the coolant comes out a small weep hole in the shaft casting area as well.... Fun, fun, fun...
