Phil,
Just an FYI. I had the same 10kw quiet diesel in my Monaco and unknown to me the previous owner had it serviced and the servicing dealer overtightened the drain plug.
Since this part of the radiator is a material made of a hard plastic, the over tightening cracked the housing that the plug went into. They tried to repair it with some type of epoxy but it only lasted about a year.
When I bought the coach and changed out all the fluids, I found the crack as I had some seepage after refilling the radiator. I ended up buying a new radiator from Cummins Power South in Jax and they installed it. I don't have the invoice in front of me but I remember around 1800 for the radiator and the install. I think the radiator cost was in the $750-850 range.
Find out if the leak is around this plug and when you replace it, take great care in using the proper torque to reinstall the plug or you may be back to square one.
