With the drain plug loose but not fully removed, flush out the system with running water. Loosen Tighten Tighten Loosen To change coolant WARNING Removing the Cooling System Cap: Removing the cooling system cap while the engine is running or hot is dangerous. This might lead to cooling system and engine damage and could result in serious injury from escaping hot coolant or steam. Turn off the engine and wait until it's cool. Even then, be very careful when removing the cap. Wrap a thick cloth around the cap and slowly turn it counterclockwise to the first stop. Step back while the pressure escapes. When you're sure all the pressure is gone, press down on the cap ― still using a cloth ― turn the cap, and remove it. 1. Remove the cooling system cap. 2. Only when the engine is cool, loosen the radiator drain plug and drain the coolant into a suitable container. Properly dispose of the used coolant. 4. Drain the system completely and retighten the plug. Add as much ethylene-glycol-based coolant mixture and water as necessary to provide freezing and corrosion protection. 5. In extremely cold climates, add the mixture percentage recommended in the coolant mixture percentage table. 6. Reinstall the cooling system cap. 7. Run the engine at idle for about 10 minutes, then turn it off. If the coolant level warning light comes on during this time, turn the engine off. After turning off the engine, inspect the drain plug and the water hoses for leaks. 8. After the engine has cooled, remove the cooling system cap and inspect the coolant level. If it's low, repeat steps 5 to 7. 8-17 Form No.8T69-EA-04G
