deflecting the air through the fins for giving more
efficient cooling
The radiator filler cap (Fig. 20) has been placed under
the hood on all new cars to aid in giving a streamline
appearance to the car and to prevent the spilling of
anti-freeze solution and rusty water, on the hood.
Fig. 20. The radiator filler cap is located under the
hood. It is on the left side on the 370-C and 452-C and
on the right side on the Cadillac V-8 and La Salle, to
correspond to the location of the oil level indicator
The filler opening is on the same side of the engine
as the oil level gauge, it being on the right-hand side
in the 345-C and 355-C cars and on the left-hand side
in the 370-C and 452-C. When filling the radiator,
the water level should be brought to a point about 1 ½
inches below the filler opening.
The construction of the radiator shutter and auto-
matic shutter control is identical with that of the
Water Passages
