COLD WEATHER
PRECAUTIONS
As the
cooling
system
is
pressurized,
relatively high
temperatures
are
developed
in
the
radiator
upper
tank. For
this
reason
anti-freeze
solutions having
an
alcohol
base
are
unsuitable
owing
to
their
high
evaporation
rate
producing
rapid loss of
coolant
and
a
consequent
interruption of
the
circulation of
coolant.
Only
anti-freeze
solution of
the
ethylene
glycol
type
incorporating the
correct type
of
corrosion inhibitor
is
suitable for
use
in
the
cooling
system,
and the
recommended
make
is
Bluecol,
or any
anti-freeze
solution
which
conforms
to
Specification
BS.
3151
or
BS.
3152.
The
anti-freeze
solution
should
be
made
up
in
the
proportions
given
in
the
table
below.
It
is
advisable
for
vehicles
with
an
anti-freeze
solution
in
the
cooling
system
to
have
an
identification
mark
on
the header
tank of
the
radiator.
The following
precautions
are necessary
on
vehicles
so
marked.
Make
sure
that
the
strength
of the
mixture
is, in
fact
up
to
that
instructed
on
the
container of
the
particular
anti-freeze
solution
used.
The
strength of
the
mixture
must
be
maintained
by
topping
up
with the
anti-freeze
solution
as
necessary
when
the
system
is
hot. Topping
up
with
water
alone
will reduce
the
degree of
protection
provided.
If the
cooling
system
has
to
be
emptied
run
the
contents
into
clean
containers,
strain,
and
use
again.
Anti-freeze
can
remain in
the
cooling
system
for
two
years
provided that
the
specific
gravity of
the
coolant
is
checked
periodically
and anti-freeze
added
as
required.
Specialized
equipment,
which
can
be
obtained
from
the
anti-freeze
manufacturer,
is
necessary
to
check
the
speci■c
gravity.
After
the
second
winter,
drain
the
system
and flush
out.
Re■ll
with fresh
water
or
the
recommended anti-freeze
solution.
If
for
any reason
the
coolant
is
lost
and the
system
is
■lled
with
water
remove
the
identi■cation
mark from
the
radiator header
tank.
