C - De-aeration Cap

Thermostat, thermostat gasket, and de-aeration tank cap should be replaced whenever system is flushed.

INITIAL change interval is 6 years or 6000 hours, provided cooling system is topped off using only John Deere Cool-Gard II™ and premix and coolant is tested at recommended intervals. After initial service, the SCHEDULED interval (2 years or 2000 hours) can be extended up to 6 years or 6000 hours depending on coolant used and if coolant is tested at recommended intervals. Follow recommendations in ”Drain Intervals for Diesel Engine Coolant” in Fuels, Lubricants and Coolant section of this manual.

NOTE: When service is performed on cooling system, make sure to check coolant daily for the next three days of operation. The most effective way to check coolant level is when tractor engine is cool. If coolant is low, fill de-aeration tank to mark on tank.

CAUTION: Explosive release of fluids from pressurized cooling system can cause serious burns.

Shut off engine. Only remove cap when cool enough to touch with bare hands. Slowly loosen cap to first stop to relieve pressure before removing completely.

  1. Park tractor, turn key switch to OFF and allow radiator to cool.

    NOTE: Throughout the draining, flushing and filling procedure, set cab temperature to highest setting (B) and leave set to the highest setting to ensure that fluids are drained from heating/Air conditioning unit. If either cab temperature setting (B) is not set to highest setting or key switch is not turned to Run, system will not completely drain.

    See your John Deere™ dealer for recommendations on cleaning solutions.

  2. Turn key to RUN Position (A), then set cab temperature setting (B) to highest setting.

  3. Open hood and remove de-aeration tank cap (C).

  4. Place catch pan under radiator drain valve (A).
