Well, think of how a small blow heater works. Your cooling system is kind of similar, but instead of pushing hot air around a room, it pulls heat away from your engine.
The cooling system works by pumping a mix of coolant and water through a series of passages and cavities on your engine. The fluid gets hotter as it circulates, it then gets transferred through hoses and a pump to a large radiator which is mounted at the front of your car.
The forward movement of your car and the fan then do their bit to disperse the heat to the atmosphere, keeping your engine’s temperature safe and just right.
So, that’s the engine cooling part covered – but your car’s cooling system isn’t done there. It also warms you up on those cold winter mornings as you turn up the heat dial, blowing warm air into the car’s cabin. It even helps to heat up your car engine when it first starts.
