Which outcome occurs when overheated engine coolant boils within a closed cooling system?

💡 Explanation

When coolant boils due to engine overheating, the phase transition increases pressure within the sealed cooling system due to the much larger volume of water vapor based on the ideal gas law, exceeding material limits. Therefore radiator rupture occurs, rather than cavitation, converter failure, or piston seizure which arise from unrelated overheating mechanisms.
