origin of coolant leak from D60??

[luckyron1]

We have a slow coolant leak that I first noted after getting a low
coolant warning upon start-up. I topped off the reservoir with the
appropriate diesel 50/50 mix and it did go away, at least for about 700
miles or so. So, I added some more 50/50 and ran the engine for about
an hour and checked it all around and underneath and no leaking at
all. So, I shut it off, slipped a piece of clean cardboard beneath the
block and this morning I noted a little puddle of coolant on the
cardboard at the left forward part of the block, which is the radiator
side on this bird--when viewed from the rear of the coach. It does
appear to be coming from behing the block, away from the radiator. I
know from looking at a basic D60 engine that the water pump isn't back
there. Hoses?? Any ideas???

Thanks

On the "left side" of the engine (standing in front) there are 4
coolant hoses (about 4 inches long each) that have "double" clamps
running parallel to the block (front to back), just above the "oil
filters" and "bus air conditioner lines". I would suspect 1 of them
has a "slight leak" and you can just tighen up the clamps.

Ron & Ruth,

Had a similar problem - found a slightly loose hose clamp. Would only
take about a 1/2 turn but it stopped the leak. Usually, the heat of the
engine would evaporate the moisture before I could find it. Some are
real hard to detect. I have found that toilet paper is great for
detecting small leaks as it shows the slightest dampness. An old
plumber's trick.

Hey thank you! I'll air it up, extend the jacks, and
have a close look at 'em.

My thanks to all those that responded on this issue.
I exercised the engine today and got underneath it and
sure enough spotted a little leak that appears to be
due to a loose hose clamp. Simple enough to fix if
you can get to it but unfortunately there's another
hose in the way and the clamp screw is pointed the
wrong direction. I'll have a mechanic take care of it
when I take it in for routine maintenance later this
month. At least now I'm not in the position where
they might be able to sell me a new water pump or
something. Ha!
