Adding Coolant

CAUTION:

TS281-UN-15APR13

High Pressure Fluids

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

IMPORTANT: Never pour cold liquid into a hot engine, as it may crack cylinder head or block. DO NOT operate engine without coolant for even a few minutes.

John Deere Cooling System Sealer may be added to the radiator to stop leaks on a temporary or emergency basis only. DO NOT use any other stop-leak additives in the cooling system. Leaks should be permanently repaired as quickly as possible.

Coolant level should be kept between the MIN COLD and MAX COLD marks on surge tank. Add coolant as follows:

1. Remove surge tank cap.

   IMPORTANT: Avoid coolant contamination. When adding coolant to the system, use the appropriate coolant solution. See Diesel Engine Coolant (engine with wet sleeve cylinder liners) in Section 10 for mixing of coolant ingredients before adding to system.

   Do not overfill cooling system. A pressurized system needs space for heat expansion without overflowing.

2. Fill surge tank until coolant level is at the MAX COLD mark on surge tank.

3. Reinstall surge tank cap.
