4. When coolant is added, coolant level
may drop the first time the engine is
started. After operating tractor briefly,
allow system to cool and recheck
coolant level.
5. To drain coolant, always open both
coolant cocks located at the crankcase
side and at the lower part of the radia¬
tor; simultaneously open the radiator
cap as well. With the cap tightly closed,
a complete drain of coolant is impossi¬
ble.
Checking Level, Adding and Changing Coolant
(See Figure 42)
■^NOTE
The radiator screen must be removed before
the radiator pressure cap can be removed.
Refer to RADIATOR SCREEN CARE.
1. Remove the radiator pressure cap, and check to
see if water reaches the supply port.
2. In the event of insufficient coolant, fill the radiator
with proper coolant. In addition, check two drain
cocks at the lower part of the radiator and the
side of the crankcase to see if they are securely
closed.
Tractors shipped in the United States and Canada
have the cooling systems filled with antifreeze solu¬
tion.
Hot Weather Operation
We recommend the use of water with the addition of
cooling system conditioner. The boiling point of
WATER LEVEL FULL

ethylene glycol solution is higher than that of water,
but the ability to transfer heat is less. As a result, the
engine will run cooler with conditioned water.
Other than Hot Weather Operation
We recommend the use of antifreeze with a mixture
ratio to protect the coolant to the lowest anticipated
temperature or a minimum of 33 percent antifreeze for
rust and corrosion protection.
RADIATOR COOLANT MIXTURE
Total coolant -1 U.S. gallon (8 pints).
Coolant consists of 50-50 mixture - 2 quarts water, 2
quarts antifreeze (ethylene glycol).
■i^NOTE
Water and antifreeze must be mixed prior to
filling radiator.
RADIATOR SCREEN CARE
▲ WARNING
Do not service the radiator screen when the
engine is running.
A WARNING
Use care to avoid burns from hot engine
when servicing radiator screen.
A
CAUTION
Radiator screen must be cleaned before
each use and kept free of debris.
■^NOTE
Radiator screen must be cleaned more fre¬
quently in dusty and high grass cutting con¬
ditions. This is to prevent overheating of the
engine.
To remove the radiator screen, lift the hood and
remove the wing nut and washer from the upper rear
corner of the right side panel. Pull outward on the
