Losing coolant

[Pete Masterson]

Greg,

Your description fits what's in the DD Series 60 engine model as
well. The "fill tank" is pressurized and the overflow just goes out
via a tube onto the ground. There is a volume of air as headroom in
the tank. The sight glass is intended to be half-full when the water
level (cold) is correct. That leaves 3 or 4 inches above the water as
expansion space.

While BB didn't design a puke tank into the system, it wouldn't be
difficult to add one, if you should desire to, assuming you can find
a practical location that doesn't interfere with the other odds and
ends in the engine room.
