How does coolant get into an engine?
The coolant in an engine is passed through tubes inside the radiator, where heat it has absorbed from the engine is dissipated into the atmosphere , before the coolant returns to the engine. Coolant enters the pipes in an overheated state, causing it to become highly pressurised (aided by turbulence inside the radiator pipes).
