(2) Close the draincocks (13) on the radiator bottom extension tube and on the left side of the engine.
(3) Fill the radiator with clean water. When filling the radiator with antifreeze, allow room for expansion. Fill the
radiator until the antifreeze solution is about one-half of an inch below the overflow pipe.
Caution: If the engine overheats because of lack of coolant, allow it to cool before filling the
radiator; otherwise, there is danger of cracking the cylinder head and block. If it is necessary to fill
the radiator before the engine has cooled, be sure to fill it very slowly with the engine running at fast
(4) Start the engine and check all connections for leaks.
a. Description. The radiator consists of the top tank (1), radiator core (4), and bottom tank (11). The radiator filler (2)
