more of the radiator is covered by the fan. The radiator
top tank is larger, increasing reserve cooling capacity.
The new radiatdr grille also has greater opening area
and provides better air distribution.
A new seven bladed fan having symmetrically spaced
blades delivers exceptionally large volumes of air, yet
is unusually quiet.
Thermostatically operated radiator shutters are provided.
The thermostat is now in the rear of the radiator
top tank which improves service accessibility and protects
the thermostat from cold air blasts which might
otherwise cause irregular operation. The bayonet type
of pressure valve filler cap is used.
ELECTRICAL SYSTEM
A large 21 plate 164 ampere hour battery is used in the
Sixteen. It is mounted under the right side of the
front seat.
The battery is maintained at full capacity by an
improved Peak Load Generator. Both voltage regulation
and current control features are provided which
insure a constant rate of proper charge throughout the
car's speed range, depending upon battery condition
and the number of electrical accessories in use. Generator
charging ability at low speeds has been increased.
An unusual feature of the new Sixteen generator is
its drive gear. Both fan and generator are driven by
the same dual belts, but a friction generator drive is
provided which lifts the generator speed above the fan
speed. This is accomplished by a rubber driving ring
against which is pressed the generator driving wheel.
The fan mounting bracket is adjustable, permitting it
to be raised or lowered for belt tension. The generator
front cover is secured to the fan mounting bracket so
