Changing Coolant

causym CAUTION: Do not open cap (A) 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).

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

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

Close drain plug 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 drain plug again, and this time fill the system with the specified coolant (see section "Fuel, Lubricants, Hydraulic Oil and Coolant").

On tractors with AutoPowr, hose (D) must also be removed from the intercooler.

Add coolant up to the "max." mark.
