A coolant recovery
tank
kit is supplied with each Westerbeke diesel engine.
The
purpose
of
this recovery
tank
is
to
allow for engine coolant expansion
and
contraction, during engine operation, without the loss
of
coolant
and
without introducing air into
the
cooling system.
This
coolant recovery tank kit is supplied with
each
Westerbeke diesel engine.
The
purpose
of
this
recovery
tank
is to allow for engine coolant expansion
and
contraction, during engine operation, without
the
loss
of
coolant
and
without introducing
air
into
the
cooling system.
This
coolant recovery tank should be installed at,
or
above, engine manifold level,
in
a location where it
can
be
easily monitored
and
where coolant
can
be
easily added
if
needed (see
the
figure below). A
stainless steel mounting bracket is supplied with
each
kit along
with
a 30
inch
length
of
clear
plastic hose
and
clamps to connect
the
hose between the engine's manifold fitting to
the
hose spud on
the
base
of
the
recovery tank.

Tank
COOLANT RETRACTION
COOLANT EXPANSION
Coolant
from
the engine,
when
heated during engine operation, will expand, lifting
the
spring-loaded
manifold pressure cap,
and
enter the recovery
tank
by way
of
the
hose connecting the recovery
tank
to
the
manifold.
When
the
engine is shut down and cools, a small check valve in the pressure cap is opened by
the
contraction
of
the engine coolant, allowing some
of
the
coolant in the recovery tank to
be
drawn
back into
the engine's cooling system, free
of
air without loss. Periodically check
that
the passage (A) between
the
90° fitting
on
the
manifold
and
the filler neck in the manifold is clear so coolant flow
in
either direction.
