Starting with Engine Warm or Hot
When restarting a hot engine, depress the accelerator pedal to about onethird of its travel before pressing the starter button, the choke control
should not be used.
Warming up
In order to minimise cylinder wear when starting from cold in winter,
the engine should be warmed up quickly. Idle the engine until the oil
circulates and then speed it up. It should not be allowed to idle for long
periods and must not be raced up to high speeds when cold. An engine
speed of approximately 1,500 r.p.m. may be regarded as a desirable
warming up speed.

COOLING SYSTEM
Filling
(see page 13).
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
Anti-freeze,
Castrol
Anti-freeze,
Shell
" 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.
LUBRICATION
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
52 and 53
.

GENERAL UPKEEP
Draining
To drain the engine, gearbox and rear axle, remove the plug provided
beneath each unit.
This process is assisted by opening the filler to allow
ingress of air and by draining when the oil is hot, i.e., immediately after
a run.
ENGINE
Only first quality oils are recommended for use in the engine sump. These are
of correct viscosity and character to afford complete lubrication protection
for normal driving.
protection must
Additives which dilute the oil or otherwise impair this
not be used.
Engine Oil Drain Period
The frequency of the drain period should be related to the driving conditions
to which the vehicle is subjected. 3,000 mile intervals are recommended for
average driving conditions as defined below.
This should be reduced for
unfavourable conditions and may be extended for those more favourable.
Favourable
Long distance journeys, with little or no engine idling, on well surfaced
roads, reasonably free from dust.
Average
Medium length journeys on well surfaced roads with a small proportion of
stop/start operation.
Unfavourable
Any of the following:
(a)
Frequent stop/start driving.
Operation during cold weather, especially when appreciable
(b)
engine idling is involved.
(c)
Where much driving is done under dusty conditions.
An upper cylinder lubricant may be used to advantage, during the runningin period of a new engine. The lubricant should be mixed with the fuel in the
proportions given on the container.
Such lubricants
may be used with
advantage throughout the life of the vehicle, particularly during wintry
weather.

The Oil Filter
The oil filter is designed to filter the
oil to a very fine degree. It will continue to do this provided that the old
cartridge (B) is removed and a new
replacement cartridge is fitted at periods
not exceeding 6,000 miles. Should this
operation be neglected, the cartridge
will become choked and unfiltered oil
will then be passed to the engine via the
balance valve in the filter. To renew the
cartridge,
unscrew the securing bolt
(C), remove the container and withdraw
the cartridge.
Wash out the container to remove
foreign matter trapped by the filter, and
discard the old container washer (A),
replacing it with a new one each time
the cartridge is renewed.
When reassembling the container, ensure that
the washer is correctly positioned in the
groove in the filter body.
Do not
tighten the bolt (C) more than is necessary to obtain an oil-tight joint.
Drain
the engine oil and refill with fresh oil
before re-starting the engine.

miles
remove the
dampers (indicated by arrows) and
replenish the dashpots with oil. The
oil level is correct when, utilizing
the damper as a dipstick its threaded
plug is approximately ¼"above the
dashpots,

Apply oil to the throttle linkage but
do not oil the bearings of the transverse rod attached to the bulkhead
as this will seriously deteriorate the
sealing compound.
