Coolant Helps Keep Vehicle Engines at Safe Temperatures
A car engine gets very hot while it runs.
Coolant is a liquid that travels through the engine and picks up extra heat.
It then goes to the radiator, where it cools down.
After that, it travels through the engine again.
This cycle helps the engine stay at a safe temperature.
In cold weather, antifreeze in the coolant helps stop the liquid from freezing.
Keeping the cooling system working properly helps protect the engine.
Coolant, also called antifreeze, helps keep a vehicle’s engine at its optimum operating temperature.
It circulates through passages in the engine block and cylinder head, absorbing heat from combustion.
The heated coolant flows to the radiator, where it cools before circulating back through the engine.
Without an effective cooling system, an engine can overheat, lose performance, or suffer damage.
Antifreeze in the coolant mixture helps prevent freezing and engine-component damage in cold weather.
