How a Cooling System Works

A cooling system is a collection of components and liquids that interact seamlessly to manage a motor’s running temperature for maximum efficiency.

This system consists of pathways within the motor block and its heads, a water pump, a drive belt, a thermostat, a radiator with a cap, and coolant hoses.

The fluid coolant that runs throughout cooling equipment tolerates severe heat and cold and includes rust preventatives and oils that ensure the cooling system operates efficiently.

Water Pump

The impeller of the water pump centrifugally pulls antifreeze out of the radiator and forces it inside of the motor block.

Any time this pump detects a leaky seal, damaged case, snapped impeller, or gear failure, the whole cooling system can be adversely affected and begin overheating.

As antifreeze courses throughout a cooling system, it is heated by the motor prior to reaching the thermostat, where its temperature is measured and a pathway opened for it to pass into the radiator.

Should the thermostat get jammed or just stop functioning, the whole cooling system will be impacted.

After it’s discharged from the thermostat, heated coolant passes through a tube where it is cooled down by the radiator. Based on the automobile’s speed, ventilation is supplied as the vehicle drives down the street and by special fans.

Radiator obstructions (including those that block both air and coolant flow) will hinder its heat-dispersing capability. A faulty electrical cooling fan or clutch may restrict air from passing throughout a radiator and can result in serious water pump deterioration.

When the temperature of antifreeze rises, the amount of pressure within a cooling system increases as well. The radiator cap typically controls this pressure.


The right pressure is needed to keep the water pump properly sealed and lubricated. Raising the pressure within the system also increases the antifreeze’s boiling temperature.

With every extra pound of pressure, the boiling temperature increases by 3˚F. Once the pressure exceeds the fixed pressure limit, a spring-triggered cap flap will open to discharge the pressure.

Any time a motor overheats, its thermostat and radiator cap ought to be changed.

It is wise to routinely check the quality of a cooling system’s gear bands and hoses. Worn out hoses and/or oil-clogged bands cause major damage over time to the whole cooling system. Maintaining the correct degree of belt stretch is another essential element.

Users should check their vehicle maker’s handbook to identify the ideal kind of antifreeze for their car. The correct combination of antifreeze with purified water is a crucial component in preventing a system from overheating.

Many part suppliers today sell premade formulations of antifreeze and water. Although it might appear to be an unneeded additional cost, ensuring the purity of the premade formula is worth it in the long run.
