(24)Cooling System - Changing Antifreeze Solution(1)
NOTE: When permanent antifreeze and water solutions are used in the cooling system, the solution should be drained and replaced every 2000 hours, or yearly.
When additions of inhibitor are made to the cooling system every 500 hours, or three months, it is not necessary to drain and refill yearly.
Whenever draining and refilling the cooling system, always recheck the coolant level when the engine reaches normal operating temperature.
Use clean water that is low in scale forming minerals - not softened water.
Check specific gravity of antifreeze solution frequently in cold weather to assure adequate protection.
Add AVSpare Corrosion Inhibitor. Follow recommendations given on container.
|
Inhibitor contains alkali, avoid contact with skin and eyes. |
|
NOTE: The engine cooling system is protected to -20°F (-29°C), with permanent-type antifreeze, when shipped from the factory.
- 1. Run engine until coolant is at operating temperature. Park machine on level ground and stop engine.
- 2. Loosen filler cap slowly to release pressure. Remove filler cap.
- 3. Open radiator drain valve and allow coolant to drain.
- 4. Remove drain plug from engine oil cooler.
- 5. Install engine oil cooler drain plug.
- 6. Close radiator drain valve.
- 7. Mix antifreeze solution to provide protection to the lowest expected ambient temperature.
- 8. Add coolant slowly to proper level.
- 9. Install radiator filler cap.
- 10. Start machine. Recheck coolant level after operating for a short period.
(1)If machine is to be stored in or shipped to an area with below freezing temperatures, cooling system must be drained completely, or protected to lowest expected ambient temperature.
