Remove the radiator cap again and insert a funnel into the radiator filler hole.

Pour approximately 1.7 quarts of coolant into the radiator or fill until you can see coolant near the filler neck. Use one hand to stabilize the funnel to prevent spills.

Towards the end of refilling the cooling system, take short breaks in filling to allow air bubbles to work their way out of the system. You can turn the engine on for a couple seconds to help pull coolant through the system.
