The cooling heating system utilizes the radiator, fans, fan clutch, water pump, gaskets, engine block and heads, thermostat, hoses and the heater core.

So, The cooling heating system produces an enormous amount of heat – enough to cause serious damage to your engine.

So, A radiator is a type of heat exchanger. Consequently, Radiators work by circulating coolant through thin metal fins, which allow the heat to flow to the air outside.

Water Pump

A water pump is vital to a car engine’s operation because it ensures the coolant keeps moving through the engine. Also, Early signs of a water pump failure are coolant leaks, or a strong coolant odor.


The thermostat decides when coolant should be run through your engine. So, A faulty thermostat may cause your engine to meltdown if it decides to not send coolant to your engine.


So, Your car’s coolant is a mix of water and ethylene glycol. Consequently, Ethylene Glycol is what makes up your coolant as it stops the water in your car from freezing. Ethylene Glycol also lubricates the moving parts it may come in contact with, such as the water pump.

Finally, An engine generates so much heat from combustion that if it isn’t continuously cooled, it can suffer serious damage. Furthermore, Virtually all modern vehicle engines are liquid-cooled, using water blended with antifreeze to keep it from freezing.
