 Following are the Main Parts of the Cooling System in the Car:

1. RADIATOR:

It cools off the anti-freeze/coolant mixture by allowing air to pass through the tube/fin area to dissipate the heat generated by the engine.

2. WATER PUMP:

It draws the cooled anti-freeze from the radiator and pumps it through the engine block, cylinder head(s), heater core, and back to the radiator.

3. FREEZE PLUGS:

It is actually a steel plug designed to seal holes in the engine block and cylinder head(s) created from the casting process. In freezing weather, they may push out if there is not enough anti-freeze protection.

5. HEATER CORE:

It provides heat to the interior of the car by using heat removed from the antifreeze and blown in by the blower motor. May cause steam, odor, or actual dripping inside the car when it leaks.

6. THERMOSTAT:

It controls the minimum operating temperature of the engine. The thermostat is closed when the engine is cold to speed warm-up and opens when normal operating temperature is reached to allow the anti-freeze/coolant to pass through the radiator.

7. HOSES (Radiator, Heater, By-pass):

It connects the other main components of the cooling system. Hose manufacturers recommend replacing it every 4 years regardless of appearance because there may be deterioration of the inside of the hose which cannot be seen.

8. COOLING FAN:

Most front wheel drive cars use this because of the transversely mounted engine. It is turned on by a system of sensors and relays when the engine reaches about 230 F and stays on until R is cooled to about 200 F.

9. PRESSURE CAP:

A pressure cap, also known as a radiator cap, is a device that seals a vehicle's cooling system to maintain pressure and increase the boiling point of the coolant.

10. TEMPERATURE SENSOR:

A coolant temperature sensor (CTS), also known as an engine coolant temperature sensor (ECT), measures the temperature of the coolant in a car's cooling system.
