A 2006 Chevy Impala typically requires about 7 to 8 quarts of antifreeze for a complete cooling system fill, which is roughly 1.75 to 2 gallons. It's important to check the owner's manual or the vehicle's specifications for the exact capacity, as it can vary slightly based on the engine type. Always ensure that you use the correct type of antifreeze specified for your vehicle.
I have a 2002 Chevy Impala. I think the gas tank holds about 15 gallons. Actually, it's 17 gallons.
