How much coolant does a 350 hold?

A typical small-block Chevrolet 350 engine holds approximately 4 to 5 quarts of coolant in the engine block itself. However, when considering the entire cooling system, including the radiator, hoses, and heater core, the total capacity can range from about 10 to 15 quarts, depending on the specific vehicle and its cooling system design. Always refer to the vehicle's service manual for the exact specifications.
