Change Coolant

causym CAUTION: Do not open cap (A) of expansion tank before coolant temperature is below boiling point. First loosen the cap to relieve pressure, then remove cap completely.

NOTE: If COOL-GARD is not used, the drain interval is reduced to 2 years or 2000 hours of operation.

1. On tractors with cab, turn the heater control as far as it will go to the right.

2. First loosen cap (A) and then take it off.

3. Turn connect/disconnect control (B) anti-clockwise as far as it will go.

4. Place a container under the drains to trap the coolant as it emerges. Open drain plug (C) and drain screw (D).

As soon as system is empty, close drain plug (C) and drain screw (D) and fill the system with clean water.

Run the engine until it reaches operating temperature. Shut off engine and drain cooling system.

Close drain plug and drain screw again and fill the system with clean water.

IMPORTANT: Never pour cold water or coolant into the hot engine. Always use warm water or wait until engine has cooled down.

Again run engine until it has reached operating temperature. Shut off engine and drain system again.

Close the drain plug and tighten the drain screw to 14 N·m (10 lb-ft). Add the prescribed coolant (see Fuel, Lubricants, Hydraulic Oil and Coolant section) to the system until coolant is level with the max. mark on both tanks.

Slacken off the clamp (E) on the coolant pump until coolant emerges from the loosened connection. Re-tighten clamp (E).
