Repair Procedures

Coolant Replacement and Air Bleeding

Hyundai Palisade. Repair procedures
  • Be careful not to damage parts located under the vehicle (floor under cover, fuel filter, fuel tank, and canister) when lifting the vehicle with a lift. (Refer to General Information - Jack Lifting Points and Support Points)
Hyundai Palisade. Repair procedures
  • Never remove the radiator cap when the engine is hot. Serious scalding may be caused by hot coolant spraying out of the radiator under high pressure.
Hyundai Palisade. Repair procedures
  • When filling the engine coolant, close the relay box cover and be careful not to spill coolant on electrical parts or paint. Wipe up any spilled coolant immediately.
  1. Make sure the engine and radiator are cold to the touch.
  2. Remove the radiator cap (A).

  3. Remove the engine cover. (Refer to Engine and Transaxle Assembly - Engine Cover)
  4. Loosen the drain plug (A) and drain the coolant.

  5. Tighten the radiator drain plug securely.
  6. Remove, drain and reinstall the reservoir. Fill the tank halfway with water up to the MAX mark, then up to the MAX mark with antifreeze.
  7. Fill the radiator with water through the radiator cap and tighten the cap.
    Hyundai Palisade. Repair procedures
    • To bleed air most effectively, slowly pour in water while squeezing the upper/lower radiator hoses.
  8. Start the engine and let it warm up to normal operating temperature. Wait until the cooling fan turns on 2-3 times. Rev the engine to help purge trapped air. Turn off the engine.
  9. Wait until the engine has cooled down.
  10. Repeat steps 1 through 8 until the drained water is clean.
  11. Slowly fill with a mixture of coolant and water (45-60%, or 45-50% in northern regions: America, Europe and China) through the radiator cap. Squeeze the upper/lower radiator hoses to easily release air.
    Hyundai Palisade. Repair procedures
    • Use only the specified antifreeze/coolant.
    • For best corrosion protection, the coolant concentration must be maintained year-round at a minimum of 45-60%. Coolant concentrations below 45-60% may not provide sufficient corrosion or freeze protection.
    • A coolant concentration above 60% reduces cooling efficiency and is not recommended.
    Hyundai Palisade. Repair procedures
    • Do not mix antifreezes/coolants of different brands.
    • Do not use additional rust inhibitors or anti-corrosion products; they may be incompatible with the coolant.
  12. Start the engine and let it run until the coolant begins to circulate.
  13. When the cooling fan is operating and the coolant is circulating, add coolant through the radiator cap.
  14. Repeat step 11 until the cooling fan has cycled 3-5 times to bleed air from the cooling system.
  15. Install the radiator cap and fill the coolant reservoir to the "MAX" (or "F") line.
  16. Run the vehicle at idle until the cooling fan has cycled 2–3 times.
  17. Stop the engine and wait for the coolant to cool down.
  18. Repeat steps 10 through 15 until the coolant level stops dropping to bleed air from the cooling system.
    Hyundai Palisade. Repair procedures
    • Bleed air from the cooling system and refill coolant only after the coolant has completely cooled. After coolant replacement, recheck the coolant level in the reservoir 2-3 days later.
    Coolant capacity: approx. 12 L (3.16 US gal, 12.66 US qt, 10.54 Imp qt)
