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.

When the engine is cold, components wear out faster. Furthermore, 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.
  • Also, thermostat, to control the temperature of the coolant.
  • Radiator, to cool the coolant.
  • Also important, radiator cap, to control the pressure in the system.
  • Interconnecting hoses.
  • Heater Core, to heat the interior.
  • Overflow or expansion tank.
  • Coolant level sensor.
  • Above all, engine coolant temperature (ECT) sensors.
  • Finally, electric cooling fans.

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

Above all, each one of these components, is crucial for sustaining the functionality, of the cooling system. So, if just one of them were to break, it would affect, the entire engine cooling system process.
