Raise front of vehicle at least 6 inches. Crawl under on you back about dead centre of the wheels. Looking up on the aluminum engine block, you will see some round frost plug holes about 1 and one half inch in diameter. One of the wholes has a red colored plastic sending unit in it with a wire attached to it. Immediately below it is a 14mm plug. Unscrew the plug, you will need a long breaker bar because it is in really tight.

You cannot change the coolant just using the radiator drain, because you will only get out 2 litres.
