Sorry for the double post, but I forgot to change the subject.
As you can see from the story below, I had some issue with coolant. When
the engine was running, there didn't appear to be leakage, but when you
turned the engine off water freely leaked. I took the engine cover off
today and road around a bit so I could watch the engine. It doesn't leak
when under load, but does leak a little at idle and a lot when off. It
doesn't drain completely, just a little until the engine cools. It appears
to be coming from the water pump area. As you know, you can't really see
much in that area. I grabbed the water pump pulley from the top and pulled,
it moved a bit and make a small clang-type noise. Am I right in thinking
that I have a bad water pump?
Thanks in advance,
Eddie Pettit

On the way to VAB, I had noticed a station in Windsor VA that had regular
for $2.38/gal. We set off for the station and arrived without issue. Since
there wasn't a deadline, and I was feeling confident, I actually turned off
the RV even though the air temp was 100F. When I did that, I noticed that
coolant was freely flowing under the RV. It looked like it was being poured
through a small funnel. My temp gauge had been fine the entire trip, so I
wasn't too concerned about it, but the guys fueling their boat seemed a bit
concerned. I looked back to where the RV had sat, while I was waiting on a
pump and didn't see any fluid there, so I assumed it was just overflow.

Eddie,
Yes, most likely the water pump bearing is gone.
If let the belt tension off it will probably be real loose.
Drain and catch the coolant before you start anything.
Good Luck
