Adjustment is made by loosening cap screws and nuts (D), (E), and (F).
When proper position has been obtained be sure to tighten screws
and nuts.
WATER PUMP
A six vane impeller packless type water pump, Fig. 15, driven by the fan belt,
is used on all models. No attention, other than periodic lubrication is required.
LUBRICATION — At intervals of 1,000
miles the water pump should be lubricated
through the metered grease fitting, located on
the top of the body, with a high grade
aluminum soap base lubricant, or other suit-
able water resistant grease.
ANTI-FREEZE
Before installing any anti-freeze w h e n
p r e p a r i n g f o r w i n t e r o p e r a tion it is
good practice to always drain and flush the
cooling system to insure unrestricted circula-
tion. Also carefully check all hose and gaskets
for leaks or signs of deterioration.
The use of Hudson Anti-Freeze,
available through all Authorized Hudson
Dealers, is recommended, as it adequately
meets all the requirements of a good, reliable
anti-freeze.
Avoid the use of anti-freeze solutions containing calcium salts, or other
ingredients which promote electrolytic action. Glucose and honey clog the
radiator ; kerosene and fuel oil when hot expel inflammable vapors and,
therefore, solutions containing these ingredients should never be used.
The following anti-freeze table will be helpful in determining the quantity of
anti-freeze required for proper protection :
