What exactly does a radiator and antifreeze do?

831 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!

If there are no visible puddle. Check that fluid is not leaking into the engine. When was the last time you changed your oil? Is the oil thick or is it watery? Is your engine producing excessive white smoke indicating water is going out the exhaust? A new radiator will not fix these issues if they exist.
