Coolant Replacement and Air Bleeding
|
|
- Make sure the engine and radiator are cold to the touch.
- Remove the radiator cap.
- Loosen the drain plug and drain the coolant.
- Tighten the radiator drain plug securely.
- Remove, drain and reinstall the reservoir tank. Fill the tank halfway to the MAX mark with water, then fill to the MAX mark with antifreeze.
- Fill the radiator with water through the radiator cap and tighten the cap.
For the most effective air bleeding, slowly pour in the coolant and squeeze the upper/lower radiator hoses.
- Start the engine and let it reach normal operating temperature. Wait until the cooling fan operates several times. Increase engine speed to help purge trapped air. Stop the engine.
- Wait until the engine has cooled down.
- Repeat steps 1 through 8 until the drained water is clean.
- Slowly fill the mixture of coolant and water (45~60%) (except North America, Europe and China: 45~50%) through the radiator cap. Squeeze the upper/lower radiator hoses to easily bleed air.

- Use only genuine antifreeze/coolant.
- For best corrosion protection, the coolant concentration must be maintained year-round at a minimum of 45~60%. A coolant concentration below 45~60% may not provide sufficient corrosion or freeze protection.
- Coolant concentration above 60% reduces cooling efficiency and is not recommended.
- 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.
- Start the engine and allow the coolant to circulate.
- When the cooling fan is operating and the coolant is circulating, add coolant through the radiator cap.
- Repeat step 11 until the cooling fan has switched on 3~5 times and sufficient air has been bled from the cooling system.
- Install the radiator cap and fill the coolant reservoir to the "MAX" (or "F") mark.
- Run the vehicle at idle until the cooling fan has cycled 2–3 times.
- Stop the engine and wait for the coolant to cool down.
- Repeat steps 10-15 until the coolant level stops dropping, bleeding air from the cooling system.
Coolant capacity: 8.4 L (8.88 US qt, 7.39 Imp qt, 2.22 US gal)
To bleed air from the cooling system and refill coolant, when the coolant has completely cooled, recheck the coolant level in the reservoir tank 2-3 days after coolant replacement.
