Filling the Cooling System

CAUTION: Prevent possible injury from hot spraying coolant. DO NOT remove radiator cap unless the engine is cool. Turn cap slowly to the stop. Release pressure before removing cap.

IMPORTANT: Use only permanent-type, low silicate, ethylene glycol base antifreeze in coolant solution. Other types of antifreeze may damage cylinder seals.

FREEZING TEMPERATURES: Fill with permanent-type, low silicate, ethylene glycol antifreeze (without stop-leak additive) and clean, soft water. Add TY16004 John Deere Coolant Conditioner or equivalent.

NOTE: All machines are shipped from the factory with a 50-50 mixture for protection to -34°C (-30°F). Adjust mixture accordingly to provide freeze protection for your machine.

FILL

• Remove cap (A) and fill radiator until coolant is visible in sight glass (B).

DEAERATION

The cooling system requires several warm-up and cool down cycles to deaerate. It will NOT deaerate during normal operation. Only during warm-up and cool down cycles will the system deaerate.

• Start engine. Run engine until coolant reaches a warm temperature.
• Stop engine. Allow coolant to cool.
• Check coolant level at recovery tank.
• Repeat Steps 1-3 until coolant level is repeatedly at the same level (stabilized).

NOTE: The level of the coolant in the cooling system MUST BE repeatedly checked after all drain and refill procedures to ensure that all air is out of the system which allows the coolant level to stabilize. Check coolant level only when the engine is cold.
