Coolant Refilling And Air Bleeding
• When working on high voltage system, the work should be performed by technicians who have completed the relevant training. It is because that lack of knowledge of the high voltage system can lead to serious accidents due to electric shock or electric leakage.
• When working a high voltage system, the technician must be recognized and observe "General Safety Information and Caution". If do not follow, serious accidents like electric shock and short circuit are caused.
• When working on high voltage system, make sure to check the Personal Protective Equipment (PPE) and high voltage shut-off procedures.
• Use a fender cover to protect the painted surface.
• Be careful not to damage the connector when disconnecting.
• Follow the instructions below when releasing the quick connector.- Remove the while pressing the quick connector clamp (A) in the direction of the arrow.- Do not touch the rubber seal (B) inside the hose.
• Check the color of the coolant in the pressure cap label and reservoir tank when replacing or replacing the coolant.
1.Disconnect the battery negative ( - ) terminal and the service interlock connector.(Refer to Battery Control System - "Auxiliary 12 V Battery - 2WD")(Refer to Battery Control System - "Auxiliary 12 V Battery - 4WD")
2.Open the reservoir tank pressure cap (A).
3.Install the radiator cap adapter (A).
4.Connect the radiator cap connection hose (A) to the radiator cap adapter (B).
5.Connect the opposite of the radiator connection hose (A) to the air pressurization valve of the SST (0K253 - J2300).
6.Install the air hose (A) to the air inlet valve of the SST (0K253 - J2300).
7.Turn the regulator adjusting knob (A) to set pressure gauge (B) to 0.2 Mpa.
8.Remove the front under cover.(Refer to Motor and Reduction Gear System - "Front Under Cover")
9.Disconnect the battery Electric Water Pump (EWP) cooling hose (A) after releasing the quick connector.[2WD]
10.Install the coolant drain adapter and hose (A) to the battery EWP and EWP cooling hose.[2WD]
11.Put the oppo site of the coolant drain adapter and hose (A) to a bucket (B).
12.Turn the pressurization valve (A) of the SST (0K253 - J2300) in the direction of the arrow to drain coolant.
13.Close the pressurization valve after draining coolant, and then install the battery EWP cooling hose (A).[2WD]
14.Drain coolant and inside the reservoir tank, and then clean it.
15.Disconnect the radiator cap connection hose (A) to the pressurization valve on the SST (0K253 - J2300).
16.Connect the radiator cap connection hose (A) to the vacuum valve of the SST (0K253 - J2300).
17.Open the vacuum valve (A) of the SST (0K253 - J2300) in the direction of the arrow, and then close when the vacuum gauge (B) reaches the green area (C).
18.Connect the coolant suction hose (A) to the SST (0K253 - J2300) coolant filler valve and place the opposite hose in the bucket (B) containing new coolant.
19.Open the suction valve (A) of the SST (0K253 - J2300) in the direction of the arrow.Turn the suction valve (A) in the direction of the arrow to fill new coolant, and then close it when the vacuum gauge reaches to '0'.

| Long range (ℓ) | 12.7 | 12.7 | |
• Use only genuine antifreeze.
• Do not mix antifreeze/coolant from different brands.
• Do not add any anti-rust.
• Use only distilled water when mixing antifreeze with water.
• If the concentration of coolant is less than 50%, corrosion or freezing may occur, and if the concentration of coolant is more than 60%, the cooling effect may be reduced, so the concentration of coolant shall be maintained at 50 to 55%.
20.Remove the radiator cap adapter (A).
21.Connect the KDS, and then perform the "Battery EWP Operation Mode for Degassing and circulation.
22.When the battery Electric Water Pump (EWP) begins to operate and the coolant begins to circulate, fill the reservoir tank with coolant.
• Friction may damage the bearing if the EWP is operated without coolant.
• If the coolant circulation is not smooth or air bubbles are still visible, repeat step 21 - 22.
• Operate the battery EWP until the air bleeding is complete.
23.Stop the battery EWP operation after air bleeding, and then fil coolant up to "MAX" line of the reservoir tank and install the reservoir cap.
• If the noise is less during EWP operation and there is no air bubbles in the reservoir tank, the cooling system air bleeding is complete.
• The cooling system air bleeding and coolant injection are performed perfectly when the coolant is completely cooled. Check the coolant level of the reservoir tank for 2 - 3 days after flushing the coolant.
• Make sure the quick connector (A) is installed securely.
24.Start the vehicle and then check the coolant hose and pipe connections for leakage.
25.Install the front under cover.(Refer to Motor and Reduction Gear System - "Front Under Cover")
