1. Set the heater temperature control lever to the highest temperature. Touch it to make sure the engine and radiator are cool.
2. Remove the radiator cap.
3. Unscrew the drain plug (A) and drain the coolant from the system.
4. Securely tighten the cooling system drain plug (A).
5. Remove the expansion tank of the cooling system. Drain the coolant from it and reinstall the tank.
6. Fill the tank halfway with water, then add antifreeze. The ratio of antifreeze to water is approximately 4:6.
7. Carefully pour coolant through the radiator cap. Wiggle the upper and lower radiator hoses to help remove air pockets.
Note:
- Use only ethylene glycol based coolants.
- For optimum protection against corrosion processes, the concentration of antifreeze in the coolant should be at least 50% throughout the year. A lower concentration of antifreeze is not able to provide protection against corrosion and freezing of the coolant in the winter.
- Antifreeze concentrations above 60% are also not recommended due to reduced cooling efficiency.
8. Start the engine and let it run for a while to allow the coolant to circulate within the system. When the electric fan of the cooling system starts working, add coolant through the radiator cap.
9. Repeat step 8 3-5 times to completely remove air from the cooling system.
10. Stop the engine and let it cool down. Screw in the radiator cap and fill the expansion tank with coolant up to the "MAX" mark.
11. Start the engine at idle speed. After the electric fan has been turned on two or three times, stop the engine and let it cool down.
12. Repeat steps 6 - 11 until the level in the expansion tank stops decreasing to completely remove air from the cooling system.
Note: Since the engine must be completely cool to completely remove air from the cooling system, recheck the fluid level in the expansion tank after 2-3 days.
