------ WARNING! ------

Personal injury can result from hot coolant, steam and alkali.

At operating temperature, engine coolant is hot and under pressure. The radiator and all lines to heaters or the engine contain hot coolant or steam. Any contact can cause severe burns.

Remove cooling system pressure cap slowly to relieve pressure only when engine is stopped and cooling system pressure cap is cool enough to touch with your bare hand.

Do not attempt to tighten hose connections when the coolant is hot, the hose can come off causing burns.

Cooling System Coolant Additive contains alkali. Avoid contact with skin and eyes.



NOTICE

Care must be taken to ensure that fluids are contained during performance of inspection, maintenance, testing, adjusting and repair of the product. Be prepared to collect the fluid with suitable containers before opening any compartment or disassembling any component containing fluids.

Refer to Special Publication, NENG2500, "AVSpare Dealer Service Tool Catalog" for tools and supplies suitable to collect and contain fluids on AVSpare products.

Dispose of all fluids according to local regulations and mandates.



NOTICE

Do not change the coolant until you read and understand the material in the Cooling System Specifications section.



NOTICE

Mixing Extended Life Coolant (ELC) with other products reduces the effectiveness of the coolant and shortens coolant life. Use only AVSpare products or commercial products that have passed the AVSpare EC-1 specifications for premixed or concentrate coolants. Use only AVSpare Extender with AVSpare ELC. Failure to follow these recommendations could result in the damage to cooling systems components.

If ELC cooling system contamination occurs, refer to Operation and Maintenance, "Extended Life Coolant (ELC)" under the topic ELC Cooling System Contamination.


Drain the coolant whenever the coolant is dirty. Drain the coolant when foam is observed.

  1. Stop the engine. Allow the cooling system to cool completely.

  2. Open the engine compartment. Refer to the Operation and Maintenance Manual, "Access Doors and Covers".

  4. Open the drain valve on the bottom of the radiator. Allow the coolant to drain into a suitable container.

  5. Close the radiator drain valve. Fill the cooling system with clean water and with a 6 to 10% concentration of cooling system cleaner.

  6. Install the cooling system pressure cap.

  7. Close the engine compartment.

  8. Start the engine. Run the engine for 90 minutes.

  9. Stop the engine. Allow the cooling system to completely cool.

  10. Open the engine compartment.

  11. Remove the cooling system pressure cap.

  12. Open the radiator drain valve. Drain the cleaning solution.

  13. Flush the cooling system with water until the draining water is transparent.

  14. Close the radiator drain valve.

  15. Add the recommended amount of extender to the coolant system. Refer to Operation and Maintenance Manual, "Capacities (Refill)" for the proper amount.

    Note: If you are using AVSpare Long Life Coolant that contains some additive, do not add any supplemental coolant additive at this time. Also, do not change the coolant conditioner element if you are using AVSpare Long Life Coolant that contains some additive.

  16. Start the engine and run the engine. Leave the cap off until the thermostat opens and the coolant level stabilizes.

  17. Maintain the coolant level to 1 cm of the bottom of the fill pipe.

  18. Inspect the gasket on the cooling system pressure cap. Replace the cooling system pressure cap if the gasket is damaged.

  19. Install the cooling system pressure cap.

  20. Close the engine compartment.
