what does the radiator do

A car radiator helps keep the engine from overheating by moving heat out of the coolant and into the air. It is a key part of the cooling system, and its job is to let the engine keep running at a safe temperature.

How it works

• Coolant absorbs heat from the engine.
• That hot coolant flows through the radiator.
• Air passing through the radiator removes the heat.
• The cooled coolant goes back to the engine and repeats the cycle.

Why it matters

Without a working radiator, engine heat can build up fast and cause serious damage or breakdowns. If you want, I can also explain how to spot a bad radiator or explain it in even simpler terms.
