COOLING
SYSTEM
(a)
Place the two pulleypressings together,
the flatter one
with
the
drilled
hole
uppermost and the second pressing on
top; feed the hub through the pressings
with
its keyway lowermost.
It
is neces-
sary
that
this
procedure is followed
for
it
ensures a visual check of
setting
the engine at T.D.C. on Nos.
1
and 4 cylinders.
(b)
Position the six bolts and secure the
hub extension
with
the nyloc nuts.
On
early production
cars,
nuts and
locking plates were used.
(c)
Insert
the rubber bushes in the fan
assembly and locate the metal sleeves
through the centres of these bushes.
(d)
Feed the four fan attachment bolts
through the
larger
diameter plain wash-
ers
and metal sleeves of the fan assem-
bly and
secure
the latter to the hub
extension.
(e)
Using
a
jig,
ascertain
the lighter side
of the assembly and
fit
the balancer
to that side. This
can
be
moved to
obtain
perfect
balance.
(f)
When
the balanced condition
is
at-
tained a
&"
drill
hole should be put
through the thinner edge of the balan-
cer and fan assembly webs until it
makes
a small dimple in the face of the
hub extension. Withdraw the four
bolts and remove fan assembly from
hub extension.

ANTI-FREEZE
PRECAUTIONS
During frosty weather it is necessary to pro-
tect the engine from damage and this
can
be
effected by
draining
the
cooling
system by
opening the tap at the lowermost portion of
the radiator, and the second tap at the right
hand side of the cylinder block.
In severe frosty weather an anti-freeze
additive to the
cooling system is strongly
recommended, for it is possible for the lower
portion of the radiator to become frozen,
even when the
car
is being driven,
restricting the circulation of the water as
well as causing ssible damage to the
P"
radiator itself. Be ore adding the anti-freeze
compound thoroughly flush out the radiator
and cylinder block, and ascertain that
all
hoses and connections are in perfect con-
dition.
Check
also that the cylinder head
nuts are tight, for
if
due to leaks, any
anti-freeze solution finds its way into the
cylinder bores serious damage may result.
The anti-freeze solution itselfdoes not usually
evaporate, thus apart from leakage, it should
only be necessary to top up with water as the
level in the radiator head drops.
This Company uses and recommends
Smiths
"Bluecol", and for protection hm various
degrees of frost the following propomons
are recommended.

Other reputable anti-freeze compounds are
available and the compound chosen should
be
used
in accordance
with
the manufac-
turer's instructiom.
It is
a
very wise precaution when using anti-
freeze
i.1
the cooling system to employ some
method of indicating the fact for the enlight-
enment of repairers who may be
called
upon
to
carry
out adjustments or the replacement
of parts.
