1. Pull hood release (A) and raise hood.

2. Check coolant level on side of de-aeration tank. Level should be at or above Min Cold line (D). If level is low, before adding coolant check for any signs of leakage. Repair if necessary.

   IMPORTANT: Do not open de-aeration tank cap (B) when engine is warm. Doing so will add air to coolant system.

   NOTE: If coolant level is low, but there is no sign of an external leak, there may be an internal coolant leak. Contact your John Deere™ dealer.

3. NOTE: 15 L engine, fill rear coolant tank (F) through de-aeration tank cap (B).

   Radiator pressure cap (E) controls pressure in coolant tanks and for water pump.

   Wait until engine is cool. Remove de-aeration tank cap (B) and add coolant as specified in Fuel, Lubricants and Coolant section of this Operator’s Manual. Do not fill above Max. cold line (C). Reinstall de-aeration tank cap.

4. Lower and secure hood.
