How many gallons antifreeze does a 5.7 hemi take?

A 5.7 Hemi engine typically requires about 16 to 18 quarts of coolant, which is approximately 4 to 4.5 gallons. However, the exact amount can vary based on the specific vehicle model and whether the entire cooling system is being filled or just a partial refill. Always consult the owner's manual for the most accurate specifications.
