I am jim from greece and I have an
aqad40. I restored it, the exchanger was
fully clogged and overheated to the
previous owner.I resurfaced the head and
there is a small crack between the valves
in the 5th cylinder(only visible if you
use a hand focus), but the pressure test
showed no leaking and I reinstalled the
head. Injectors are new, heat exchanger is
cleaned (both head and exchanger works
carried out from special personnel and i
am also mechanic).Engine runs as new and
the cooling system works perfect but I lose
some coolant, about a liter per 10 hours.I
can't find any external leaking and also I
try to find if it's loosing coolant when
engine is resting.My worse thought is what
if there is leaking in the cylinder under
several conditions and how much could be
that loss? a liter per 10 hours seems too
much for me.What is your opinion? Regards,
Jim.
