Checking Coolant Level (Coolant Recovery Tank)
1. Check coolant level at sight tube (A), BEFORE starting tractor. Level should be above lower mark when engine is cold. 2. If coolant level is low; a. Raise hood. b. Check for any signs of leakage. Repair if necessary. NOTE: If coolant recovery tank continues to require coolant be added and there is no sign of an external leak, this may indicate and internal coolant leak. Contact your John Deere Dealer for service. c. Remove coolant recovery tank cap (B) and add coolant, as specified in Fuel, Lubricants and Coolant section. d. Lower hood. |

Checking Coolant Level (Coolant De-aeration Tank)
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. Raise hood. 2. Slowly turn de-aeration tank cap (A) to relieve pressure. Remove cap. 3. Check de-aeration tank level. Tank will not be full of coolant when cap is removed. When looking in tank, if coolant tank is at least half full, do not add additional coolant. If tank is empty and recovery tank has been kept at least full cold, this indicates a leak that prevents system from recovering coolant from recovery tank. If recovery tank does not change levels between engine being cold and being warmed up, this is a sign of a leak or of being very low on coolant in the pressurized circuit. 4. Add coolant, as specified in Fuel, Lubricants and Coolant section. 5. Reinstall de-aeration tank cap. |

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