engine coolant
Prevents motor overheating
Engine coolant is a liquid circulated through an engine to absorb and transfer heat, preventing overheating.
Typically a mixture of water and antifreeze, it also protects against freezing in cold weather and inhibits corrosion.
Check your engine coolant before a long trip.
Also called simply coolant or antifreeze, though antifreeze is technically just one component.
