Draining

Taps are provided in the bottom tank of the radiator and at the rear of the
cylinder block on the right-hand side. As the cooling system is pressurised
it will be necessary, when draining, to remove the radiator cap (E) (Fig. 5).
If a heater is fined, ensure that the tap (C) (Fig. 5) is open before draining.

Anti-Freeze Mixtures

Protect the cooling system during frosty weather and reduce corrosion to
a minimum, by use of an inhibited anti-freeze. The use of Smith's "Bluecol",
Duckham's Anti-freeze, Esso
" Snowflake " or Mobil Permazone Anti-freeze (inhibited Glycol base
compound) is recommended. The cooling system is fitted with a thermostat
and there is a risk of the radiator block freezing while the engine is running
during the warming up period when the thermostat is shut, even though the
car has been left in a warm garage and water is not frozen at the start of the run.
Provide ample protection for the cooling system against a sudden fall in
temperature down to 0°F. (-18°C.) during frosty weather by using 3 pints
(Imperial) of anti-freeze.
In countries where sub-zero temperatures prevail, consult your Triumph
dealer regarding the quantity of anti-freeze required.
Do not use the same anti-freeze for more than one season since the
inhibitor becomes exhausted and the components in contact with the
cooling water may corrode.
This is one of the most important subjects in connection with the upkeep of a
car, and careful attention to the following instructions will be amply repaid by
the results obtained.
For the recommended periods of lubrication, see the lubrication
chart (page 54). The correct lubricants to be used are given on pages
.
