Radiator
Heat, then a seize
Short answer
A radiator keeps the engine from cooking itself. Water still matters. Leaks still happen.
Also: car radiator · engine radiator
How it works
Radiators are a named car part. Empty or ruined means you are walking soon.
What to do
Look at it before a long drive. Don't ignore the temperature because the bit is funny.
Don't
Don't invent a kilometre table.
