A radiator’s job is pretty straightforward – it cools down the engine. Engine combustion creates a lot of heat, and that heat needs to go somewhere. The radiator receives hot coolant from the engine – it's basically a network of really thin tubes and fins. Air flows over these fins – either from you driving or from the electric fans – and that airflow pulls the heat out of the coolant. The cooled coolant then cycles back to the engine to absorb more heat. It’s a continuous process. Think of the radiator as a key part of the whole cooling system. It works with things like the water pump, thermostat, and hoses to keep everything at a safe operating temperature. The coolant flows from the engine to the radiator, back to the engine, and so on. Without a properly functioning radiator, that heat would build up quickly and cause serious problems. It's pretty central to preventing overheating. Overheating is a major engine killer. If things get too hot, you could end up with warped cylinder heads, blown head gaskets, or even a seized engine – and those repairs are expensive. The radiator acts like a shield, protecting the engine from that extreme heat. You’ll notice if your radiator is failing because you might see the temperature gauge creeping up, steam coming from under the hood, or even a sweet smell – that's usually coolant leaking. Keeping an eye on your coolant levels is a good idea, of course.
