So, Why Does Coolant Even Matter? 

Think of coolant as your engine’s chill pill. It circulates through the radiator and engine, grabbing onto all that fiery heat and carrying it away. Without it? Your engine starts cooking like arroz con gandules left too long on the stove. Over time, coolant gets dirty. It picks up rust, scale, and all kinds of gunk that slows it down. When that happens, your radiator can’t do its job, and things start to overheat—fast.
