[Nu 2.0 MPI]

CAUTION: Never remove the radiator cap when the engine is hot. Serious scalding could be caused by hot fluid under high pressure escaping from the radiator.

NOTE: When pouring engine coolant, be sure to shut the relay box lid and not to let coolant spill on the electrical parts or the paint. If any coolant spills, rinse it off immediately.

Make sure the engine and radiator are cool to the touch.
Remove radiator cap (A).

Remove the engine room under cover.
(Refer to Engine and Transmission Assembly - "ENGINE ROOM UNDER COVER ")
Loosen the drain plug (A) and drain the coolant.

Tighten the radiator drain plug securely.
After draining engine coolant in the reservoir tank, clean the tank.
Fill fluid mixture with coolant and water (55-60%) (except for North America, Europe and China: 45-50%) slowly through the radiator cap. Push the upper/lower hoses of the radiator so as bleed air easily.
NOTE:
- Use only genuine antifreeze/coolant.
- For best corrosion protection, the coolant concentration must be maintained year-round at 55% (except for North America, Europe and China: 45%) minimum.
  Coolant concentrations less than 55% (except for North America, Europe and China: 45%) may not provide sufficient protection against corrosion or freezing.
- Coolant concentrations greater then 60% will impair cooling efficiency and are not recommended.
CAUTION:
- Do not mix different brands of antifreeze/coolants.
- Do not use additional rust inhibitors or antirust products; they may not be compatible with the coolant.
Perform the engine coolant filling mode on KDS to bleed air out of the cooling system.
NOTE: As an electric thermostat (opening temperature 100°C(212°F)) is applied in the engine, fill up the coolant and use the KDS to enter the coolant filling mode and let out the air.
