Radiator: Just the Facts

- May 22, 2019-

When it comes to cooling down your car's engine, no other part does it better than the radiator. It helps lower engine temperature through the simple process of heat exchange. As coolant flows through the engine, the fluid absorbs much of the engine block's heat. This keeps engine temperature at manageable levels, preventing the dangers of overheating.After taking heat from moving engine parts, the hot coolant returns to the radiator. The radiator is usually equipped with one to three rows of finned tubes that can hold heated coolant. The heat exchange process happens when air blown in through your vehicle's grille picks up heat from hot coolant, leaving the coolant at a lower temperature.The radiator's tubes are, however, thin and delicate. Front-end collisions can easily break these tubes, rendering the radiator useless. If you discover water dripping under your car, or you notice the engine's coolant level dropping unusually fast, then chances are good that the whole eadiator is busted.A replacement is probably due, but don't worry.

Because most automotive engines run on internal combustion, engine heat is a major problem. The many explosions that take place in the engine cylinders while the engine is running put off a fair amount of heat – and if this heat is uncontrolled, it can damage the engine itself. Savvy drivers, then, understand that it is important to monitor engine temperatures at all times. The best way to keep your engine running smoothly is with a good engine cooling system. The cooling system is anchored by the radiator, which is responsible for carrying warmed coolant fluid so that the heat can dissipate back into the external environment. Liquid coolant is pumped through a series of channels that pass through the engine compartment. Generally, the coolant is a mixture of water and chemicals known as antifreeze. Engine cooling mechanisms are most often placed near the front of the vehicle, just behind the grille. This allows for plenty of air flow in and around the cooling system, allowing for more efficient heat transfer.
