C. Close the drain plug
Important: Do not install the radiator cap.
D. Operate the engine for 5 minutes or until the
coolant temperature indicates 82° C (180° F), and
then stop the engine.
CAUTION
The cleaning solution is hot and can
cause burns.
Stay away from the discharge end of the
coolant drain.
E. Open the drain plug for the radiator, and drain
the cleaning solution into a drain pan.
F. Clean the threads on the drain plug and apply 3
layers of PTFE sealing tape.
G. Close the drain plug.
3. Flush the cooling system as follows:
A. Open the filler-neck cap.
B. Fill the radiator with clean water

G. If the water drained from the radiator is dirty,
perform steps

H. Close the drain plug
Filling the System with Coolant
Important: You must fill the cooling system properly to
prevent air locks in the cooling passages. Failing to vent
the cooling system properly can severely damage the
cooling system and engine.
Important: Use a mixture of 50% ethylene glycol and
50% water mixture or equivalent in the machine. The
lowest ambient operating temperature for this mixture
is above -37° C (-34° F). If the ambient temperature is
lower, adjust the mixture. Use a mixture of ethylene
glycol and water or equivalent in the machine all year.
1. Park the machine on a level surface, stop the engine,
and remove the ignition key.
2. Remove the radiator cap
3. Fill the radiator with coolant until the fluid level is up
to the bottom of the filler neck
Note: The coolant capacity of both the engine and
the radiator is 16.8 L (17.7 US qt).
