Dear all,
I just had to remove the heat exchanger from my motor,
a VETUS M2.05 0 hp diesel (marinized Mitsubishi) from 1985,
because it had rusted through at one end and water from the raw
water circuit came spouting out.
I realize not many of you have this particular motor, but maybe
you can give me some general advice (assuming these units work
similarly on most diesels). I am trying to figure out what all the
"orifices" are good for. There is of course a raw water inlet in the
front and a hose going to the mixing "knee" in the back. In addition,
there are two openings in the side that directly mate to similar openings
in the engine block, with gaskets. From what I can tell, these holes
simply lead to a pipe that goes through the coolant tank - in, straight
through, out. What could this be? The coolant tank itself of course
has a filler cap, but also a sideways connection (via a thick, short
rubber hose that seems to contain some mechanical valve or
similar) to the front part of the engine block. Then, in the back bottom,
another short rubber hose connects to an "exhaust" (?) pipe from the
engine, which was filled with coolant when I removed the unit.
However, this must be the exhaust because the "mixing knee" is
directly connected (with its large opening) to the rear end of the
heat exchanger. Is that correct?
If this sounds confusing, it's because I'm confused. Any ideas to make
sense of this are welcome.
