If you're talking about the spot where the arrow is pointing in my picture, I believe it is the weep port for the water pump.

If it's actively leaking you probably need a new water pump. If it's just dripping occasionally you're probably ok. You can see some drops of coolant in it in my pic, but it's not actively dripping.

That's it... Oddly enough haven't seen it leak in the past few days. It definitely leaked with the unit off with a decent size puddle underneath. I'll monitor going forward, thanx for replying. 

I have a new Coleman 2021 400 with about 10 miles on it. I noticed yesterday that it appears to be leaking coolant. After spending some time tracking it down, appears it's coming from a fitting that sticks out of the block near the oil filter. (maybe the water pump bleed port) Almost looks like there should be a hose on it. I reviewed the service manual to see if I could find what it was, but saw nothing on it. I can get a pic of it and post it, but was wondering if anybody knew what this fitting was for?
