AUSTIN-HEALKY SPRITE GENERAL MAINTENANCE
Frost Precautions: During freezing weather an anti-freeze com-
pound should be added to the coolant in the radiator.
Always flush the cooling system before adding an anti-freeze
solution, and again when removing it in the Spring.
The manufacturers of anti-freeze will provide a table indicating
the quantity to be used in providing full protection against any
degree of frost.
The strength of the solution must be maintained by topping-up
with anti-freeze solution as necessary. Excessive topping-up
with water will reduce the degree of frost protection.
The following are oflicially approved anti-freeze compounds:
Smith's 'Bluecol'; Shell 'Snowflake'; Esso 'Antifreeze'.
N.B. Where a heater is fltted under no circumstances resort
to draining the cooling system as an alternative to the use of
anti-freeze, due to the fact that it is not possible to drain the
heater unit completely by means of the cylinder block and
radiator drain cocks.
Radiator Drain Cock.
i. Drain cock.
2. Bonnet safety catch.
Turn the cock tn an anti-
clockwise direction to open.
Flushing the Radiator: To ensure efficient circulation of the
coolant and to reduce the formation of scale and sediment in the
radiator, the system should be periodically flushed with clean
running water, preferably before putting in anti-freeze in the
Autumn and again when taking it out in the Spring.
The water should be allowed to run through until it comes out
clean from the drain cocks.
HEATING AND DEMISTING~
heated fresh air to the car interior at floor level and to the wind-
screen for demisting and defrosting.
A tap controlling the flow of hot water through the heater unit is
fitted at the rear of the cylinder head. The tap is opened by turning in
an anti-clockwise direction when heating is required or shut off by
turning clockwise when the
system'is to be used for cool air ventila-
tion.
Air is drawn in to the system through a forward-facing intake and
the ram effect caused by the car's motion will provide sufficient quan-
tity of air for the heater's requirements at speeds above 25 m.p.h.
A blower motor is provided for use at lower speeds or when a greater
quantity of air is required. The blower is switched on by turning the
control on the fascia marked 'H' in a clockwise direction.
A shut off valve is incorporated in the air intake to prevent fumes
entering the car in traflic and is operated by pulling out the control
marked 'H'. The blower motor must be switched off before the valve
is closed and cannot be switched on again until the valve is returned
to the open position.
Two doors located forward at either side of the gearbox tunnel
control distribution of air between screen and car interior. F o r
heating, open the doors. For defrosting
(i.e., boosting flow of hot
air to screen) close the doors.
T HE Smith's heating and demisting system is designed to provide
Cylinder Bloclc Drain Cock.
The drain cock 'A' is lo-
cated on the left side of the
cylinder block, adjacent to
the engine rear mounting
plate. Turn i n a n a nti-
clockwise direction to open.
