How Does a Car Radiator Work?

Lead Image

The car radiator is the device that keeps the engine from overheating. If there is a problem in any of the parts of the cooling system, from the car radiator to the thermostat, it can cause many problems for your vehicle.

The Major Parts of the Cooling System

The cooling system in your vehicle has several parts. The radiator, the water pump, the fan, and the thermostat are all major components of the cooling system. They must work together for the engine to stay cool and avoid overheating. A problem with just one part, if not taken care of quickly, can cause the cooling system to fail. This can result in an expensive repair.

How the Parts of the Cooling System Work Together

You place the coolant into your radiator. The surface area of the radiator, as well as the fan located near the radiator, helps keep the coolant at a low temperature. The thermostat regulates the flow of the coolant. When the temperature of the engine increases, the thermostat allows the coolant to flow through the engine and cool it down. When the engine temperature drops, the thermostat blocks the flow of the coolant.
