Changing Coolant
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. Loosen cap (A) and take off cap (B). 3. Turn connect/disconnect control (C) anti-clockwise as far as it will go. 4. Place a container under the drains to trap the coolant as it emerges. Open drain cock (D). As soon as system is empty, close radiator drain cock (D) and fill the system with clean water. Run engine again until it reaches operating temperature. Shut off engine and drain cooling system. Close drain cock 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 cock again, and this time fill the system with the specified coolant (see section "Fuel, Lubricants, Hydraulic Oil and Coolant"). On tractors with AutoPowr, hose (E) must also be removed from the intercooler. Add coolant up to the "max." mark. |

CAUTION:
Remove caps only when coolant temperature is below boiling point. First loosen the black cap (A) to relieve pressure, then remove the green cap (B) completely.

On tractors with AutoPowr: As soon as coolant emerges from hose (E), put the hose back onto the intercooler and secure it with a clamp. Start the engine and run it for 5 minutes. Shut down the engine and add coolant up to the "max." mark. Start the engine and bring it up to operating temperature. Shut down the engine and add coolant up to the "max." mark. Turn connect/disconnect control (C) clockwise as far as it will go. Re-install and close the filler cap (B) and relief valve cap (A). For efficient cooling, the radiator screen must be kept clean. Remove any dust or oil and carefully straighten any bent fins. |
