Replacement and Air Bleeding

When KDS is available, conduct coolant change and air bleeding following the below procedure. 

1. When KDS is available, conduct coolant change and air bleeding following the below procedure.
2. Remove the pressure cap (A).

3. Remove the engine room under cover.

   (Refer to Engine And Transaxle Assembly - "ENGINE ROOM UNDER COVER ")

4. Drain engine coolant by removing the drain plug (A).

5. After coolant drain is completed, retighten the drain plug.
6. Drain coolant in the reservoir tank and then clean reservoir tank.
7. Install the coolant refill tank on the radiator and then add the mixture of anti-freeze and water (55 - 60%) (except for North America, Europe and China: 45 - 50%)
   CAUTION: Fill coolant as far as possible with engine and all power supplies shut off.

   Coolant capacity 

   Approx.9.2 l  (2.4 U.S.gal., 9.7 U.S.qt., 8.1 Imp.qt.)

   NOTE:

   • Push the upper/lower hoses on the radiator so that the air can get out easily.
   • 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 than 60% will impair cooling efficiency and are not recommended.
   • Do not mix different brands of antifreeze/coolants.
   • Do not use the additional anti-rust additives.
8. Connect the KDS.
9. Select the "ITM coolant filling mode" in the Vehicle S/W Management.

10. Start the engine.
    NOTE: Keep the engine idle.
11. Warm up the engine for 20 minutes after cooling fan operates 1 time.
12. After disconnecting the KDS, turn the ignition switch to OFF and then restart engine.
13. Install the pressure cap (A).

14. Add coolant if it is insufficient.
15. Install the engine room under cover.

    (Refer to Engine And Transaxle Assembly - "ENGINE ROOM UNDER COVER ")

When KDS is unavailable, conduct coolant change and air bleeding following the below procedure. 

1. Check that the engine and radiator cool down sufficiently.
2. Remove the pressure cap (A).

   NOTE:

   • When disconnecting the integrated thermal management module (ITM) connector, be sure to recheck that the engine and all power supplies are shut off.
   • Be careful not to allow the static electricity and any other voltage are not applied to the integrated thermal management module (ITM).
   • Keep away the magnetic objects (Ex. magnet) from the integrated thermal management module (ITM).
9. Start the engine.
   NOTE: Keep the engine with idling.
10. Warm up the engine for 20 minutes after cooling pan operates 1 time.
11. After turning the ignition switch to OFF, reconnect the integrated thermal management module (ITM) connector (A).

    NOTE:

    • When reconnecting the integrated thermal management module (ITM) connector, moisture and oil in the connector must be completely removed and foreign materials should not enter.
    • When replacing the integrated thermal management module (ITM) connector, be sure to use the specified connector.
12. Start the engine.
13. Check the integrated thermal management module (ITM) for operation by operating sound.
    NOTE: Before/after starting up the engine, integrated thermal management module (ITM) operating sound can be generated.
14. Repeat the engine ON/OFF and check the engine warning lamp OFF.
    1. Wait for 5 seconds with engine ON and then turn OFF the engine.
    2. Repeat the step  1 3 times.
    3. Check the engine warning lamp OFF when engine is turned ON a fourth time.
15. Drive a vehicle until cooling fan operates and check the remaining amount of coolant in reservoir tank while engine is hot.
16. Add coolant if it is insufficient.
17. Install the engine room under cover.
