Kia Stinger: Cooling System / Coolant

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.

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 the radiator cap (A).

Remove the engine room front 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.

Disconnect the coolant vent hose (A).

Fill with fluid mixture of coolant and water (55 - 60% / or 45 - 50% in North America, Europe and China) slowly through the radiator cap. Push the upper/lower hoses of the radiator so as to bleed air easily.

• Use only the specified antifreeze/coolant. • For best corrosion protection, the coolant concentration must be maintained year-round at 55% (or 45% in North America, Europe and China) minimum. Coolant concentrations less than 55% (or 45% in North America, Europe and China) may not provide sufficient protection against corrosion or freezing. • Coolant concentrations greater then 60% will impair cooling efficiency and are not recommended. • 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.

When the coolant flows out through the disconnected vent hose, connect the vent hose securely to the nipple.

Connect the KDS

Start the engine.

Turn off the A/C and heater, and then keep it idle for 10 minutes to raise the engine coolant temperature.

Perform the "Engine coolant filling mode".

After confirming that the condition of the vehicle is satisfied with the inspection condition, and then press the "OK" button.

Check the engine coolant filling mode entry conditions and then press the "Read" to check the current coolant temperature.

Check the current coolant temperature and then press the "OK".

The current temperature of coolant is above 75°C (167°F), engine coolant filling mode can be performed.

If the coolant temperature is above 75°C (167°F), press the "OK" to performing engine coolant fill mode.

The engine coolant filling mode is maintained until the temperature of coolant becomes 75°C (194°F).

When the engine coolant filling mode completed, press the "OK".

Disconnect the KDS.

Maintain engine RPM at 2,000 to 3,000 for about 3 minutes to promote cooling water circulation.

Keep the engine idle for 3 minutes to check the cooling fan is operating.

Maintain 15 minutes after turn off the engine.

Install the radiator cap (A).

Check the coolant level and then fill the reservoir tank to the "F" line with coolant.

Install the engine room front under cover.
