So, the primary job, of the cooling system is, to keep the engine from overheating.

However, the engine in your car, runs best at a fairly high temperature.

Consequently, engine components wear out faster, when the engine is cold. As a result, the engine is, less efficient and emits more pollution.

Above all, the cooling system, needs to allow the engine to heat up, as quickly as possible. And, then keep the engine, at a constant temperature.

So, the cooling system is made up of:

  • Passages inside, the engine block and heads.
  • Water pump, to circulate the coolant.
  • A thermostat, to control the temperature of the coolant.
  • Radiator, to cool the coolant.
  • Also, a Radiator Cap, to control the pressure in the system.
  • Interconnecting hoses.
  • Also, a Heater Core, to heat the inside.
  • Overflow or recovery tank.
  • Coolant level sensor.
  • Engine coolant temperature (ECT) sensors.
  • Finally, electric cooling fans.

Consequently, all these parts must work together. And, that will make the whole system function as intended.

Above all, each one of these parts, is crucial for keeping the cooling system working the way it should. Because, if just one of them were to break, it would affect, the entire engine cooling system process.

So, How Does It All Work

So, the water pump sends engine coolant to the engine, where it absorbs the engine’s heat. Then, it exits the engine, and runs by the thermostat. Consequently, if the engine coolant is below the maximum temperature, the thermostat stays closed. Then, the coolant is sent back to the pump. However, if the coolant is overheated, the thermostat’s valve opens, routing the coolant through a radiator first. The radiator cools the coolant, by pushing its heat to the air, before returning it to the water pump.
