Remove the cap and fill the radiator. Start the car. When the stat opens the fluid will go up and down until the stat opens. Then youll see steam and the fluid will drop in the radiator. Fill it and cap it. Then fill the coolant jug. Ty for using 2 carpros

Some cars have a hard time getting all of the air out of the coolant system.
This is a way that I do it on most cars.
