7. Engine Cooling System
A. Ge’neral
.
Cooling system service requires much more than maintaining the proper coolant
level ,in the radiator.
During warm seasOns and in warm climates, when plain water
is used as a coolant, the system must be protected against rust by a rust inhibitor
odd itive.
During cold seasons and in cold climates, the system must, of course,
be protected against freezing. At no time should the system be operated for any
length of time on plain water, without a rust inhibitor or antifreeze.
Draining,
cleaning, and filling the cooling system are covered in Para. 7, E thmugh H.
