What exactly does a radiator and antifreeze do?

830 views

So I drive a pretty old SUV and it’s had a radiator leak for awhile. I can deduce that anytime I start to run low on antifreeze it begins to overheat. But I don’t exactly understand the causation behind it. Clearly, no antifreeze—overheat. But how exactly does that happen?

Ps. I am not mechanically inclined. I never had anyone teach me about any of this so I’m learning on my own. My mechanics are really helpful! But I don’t want to bother them as they’re super busy. Thank you all!

The engine is very hot unless something is present to take away the heat. The radiator fluid, made up of antifreeze and water, is heated up by the engine and then is cooled by air in the radiator, allowing the engine to be cooled
