Flow direction arrow on filter body should point away from tank. Remove old filter and install new filter. Replace two spring clamps. Remove clamp used between filter and tank. Check for leaks.

John Deere 1025R, 1023E Cooling System

Check Coolant Level

Raise hood. Check coolant level in the recovery tank. If engine is at operating temperature, coolant level is at the FULL HOT line. If engine is cold, coolant level is at the FULL COLD line on the recovery tank. To add coolant, remove recovery tank cap. Add recommended coolant if needed. Install recovery tank cap. Lower hood.

Drain and Flush Cooling System

Shut off JD 1025R, 1023E engine. Only remove filler cap when cool enough to touch with bare hands. Slowly loosen cap to first stop to relieve pressure before removing completely. Allow engine to cool. Raise hood. Slowly open radiator cap to the first stop to release all pressure. Close radiator cap tightly. Position a pan under the radiator drain tube. Open the drain plug and allow the coolant to drain from the system. Remove the drain plug from the engine block and finish draining coolant. When coolant drains from the recovery tank, remove the radiator cap. Close radiator drain plug and install drain plug. Fill the cooling system with clean water. Run engine until water passes through the thermostat to stir up possible rust or sediment.

Stop engine immediately and drain water from the system before rust and sediment settles. Fill cooling system with clean water and John Deere Cooling System Cleaner, or Cooling System Quick Flush or an equivalent. Follow directions on the container. After cleaning the system, drain cleaner and fill the system with clean water to flush the system. Start and run engine until water passes through the thermostat. Stop engine, and drain flushing water from the system. Close all drain orifices and fill cooling system to specification. Cooling system capacity - 3.7 L (3.9 qt).
