Coolant Solution A mixture of 50% ethylene glycol and 50% water must be used in this machine. This mixture is used if the lowest ambient temperature is above -34°F (-37°C). If the temperature is lower, adjust the mixture to 60% ethylene glycol, 40% water. It is recommended that ethylene glycol and water be used in your machine all year.

NOTE: NOTE: After you fill the cooling system, mix the ethylene glycol and water completely by running the engine at operating temperature for approximately five minutes. This procedure must be done when the machine is in temperatures below 32°F (0°C). WARNING: Hot coolant can spray out if radiator cap is removed. To remove radiator cap: Let system cool, turn to first notch, then wait until all pressure is released. Scalding can result from fast removal of radiator cap. Check and service engine cooling system according to maintenance instructions. SA023
Coolant Level
Check the radiator coolant level when the coolant is cold and the engine is st o p p e d . O p e n th e re a r d o o r a n d remove the radiator cap. The coolant level must be up to the radiator cap opening. IMPORTANT: Only add the correct mixture of ethylene glycol and water to the radiator.
