    Instructions
    1
    Move the Pontiac Grand Prix to a level area and set the parking brake. Then, pop the hood and touch the radiator. If it's warm to the touch, allow it to cool off before you continue.


    2
    Twist the radiator cap one full turn. Then, step back to make sure it doesn't erupt from internal pressure. Even when radiators are cool to the touch, they can still pose a risk of spewing coolant on anyone in the area.


    3
    Place a bucket underneath the radiator and blow the drain plug. Make sure the bucket can hold 2 gallons of liquid. The drain plug on a Pontiac Grand Prix is usually on the driver's side bottom of the radiator facing the engine. However, on some models the drain plug is on the front of the radiator.


    4
    Loosen the drain plug and allow the old coolant to drain completely from the radiator into the bucket. You may need a crescent wrench to loosen the drain plug.


    5
    Dispose of the old coolant by pouring it into a sealable container. Place the bucket back under the drain plug when you finish. Because coolant is extremely toxic to people and pets, you need to very careful with it during the radiator flush.


    6
    Shut the radiator drain plug and fill the radiator with distilled water. Loosen the plug to drain the water and then, replicate this process of filling and draining until the water runs free of debris into the bucket. You can use tap water from a garden hose, but this water may damage your coolant system by leaving sediment behind in the radiator.


    7
    Close the drain plug and fill the radiator with fresh coolant until it's about an inch from overflowing. You will need 3 gallons of coolant for the regular Pontiac Grand Prix model and 4 for the GXP model. Be sure to check the drain plug for any leakage.


    8
    Start the Pontiac Grand Prix and turn the heating system to high. Allow the car to keep running until the cooling fan turns on twice. After that happens, switch off the engine and check the coolant level. If it went down, add more coolant. If not, put the radiator cap back on and close the hood.
