Section A (Cooling System)
To test
Suspend unit in a vessel of water with a reliable
thermometer.
Heat the water slowly, noting the thermometer
reading and stirring the water continually.
The thermostat valve should commence to open
and be fully open at the temperatures given in the
Data Section under "Cooling System".
Thermostats are sealed and their setting and manu
facture is specialised work. Always renew if doubt
exists. If a replacement is not immediately available,
it should be left out, as a faulty unit could cause
serious overheating.
RADIATOR-TO Remove and Refit
Drain cooling system.
Disconnect top and bottom water hoses.
Remove fixing bolts that secure radiator to baffle
plates.
Replacement is made in reverse order. Fixing bolts
and their cage nuts should be lubricated with thick
oil to prevent rusting of the bolt threads.
WATER TEMPERATURE GAUGE
This instrument is electrically operated and consists
of two units, the temperature element (trans
mitter) in the thermostat housing, and the
temperature gauge in the instrument panel. These
units are connected by a single insulated wire in
the wiring harness, and temperature is only
recorded when the ignition is switched on.
Removal of element
Drain the radiator enough to allow removal of
element without loss of water or anti-freeze.
Disconnect battery.
Remove the insulated lead from element terminal.
Unscrew and remove element.

It
is
most important that the interconnecting cable
between
the gauge and
·the
temperature element
should not
be
shorted to earth when the Ignition is
switched on. If this occurs
the
temperature gauge
winding will burn out and for this reason the
battery
should be
disconnected
or
the
end of the lead Insulated
when it
is
removed from the element terminal.
Removal of Temperature Gauge
Two electrical leads have to be disconnected and
the two knurled instrument fixing nuts removed to
allow the instrument head to be lifted out of the
instrument panel.
To Check Temperature Gauge Reading
Remove the temperature element and earth its
outer body to the thermostat housing and switch
on the ignition. Immerse the element in a small
container of almost boiling water and take the
temperature of this water with a reliable glass
thermometer. A comparison of the glass thermo
meter reading with the instrument will show if the
later is reasonably correct.
WATER PUMP
To remove and refit
Remove radiator.
Slacken by-pass hose.
Remove thermostat housing.
Slacken dynamo mounting bolts.
Remove driving belt and fan blades.
Disconnect heater hose (if fitted).
Remove four bolts and withdraw pump.
Reassemble in the reverse order, renewing
.
any
faulty joints or water hoses. When replacing the·
fan belt adjust so that there is
•r
(16 mm.) belt
slackness in the centre of the longest run of the belt.
To dismantle
