WHAT IS A COOLANT?
Engine creates a lot of energy and heat while the car is moving. It is the job of the exhaust and cooling system to make sure the engine stays cool. The coolant absorbs the heat from the engine and stops the engine water from boiling in the summer.
A coolant is a special heat transfer fluid substance that is used to regulate the temperature of engines and machines. It is also known as antifreeze, which has mostly ethylene glycol or propylene as the main ingredient. Coolant is generally 50-50 of antifreeze and water, which provides the best heat transfer. It protects the engine from freezing and also prevents corrosion of metal parts due to corrosion inhibitors that are present. They are of different types and usually appear in different colours such as green, blue etc
HOW DOES IT WORK?
Automobile engines generate a lot of heat while running and so must be cooled gradually to avoid the engine from being damaged.
The mechanisms behind a cooling system is that the coolant is passed through passages in the engine heads and blocks, as it flows it absorbs heat from the engine. The heated fluid then moves through a rubber hose to the radiator of the machine. As it passes in the thin tubes of the radiator, air streams entering the engine compartment from the grill in front of the car cools the hot liquid. When the liquid is cooled, it is sent back to the engine to absorb more heat, this is made possible by the water pump which is responsible for the fluid movement through the passages and the entire system.
Overheating can bring about an increase in the breakdown of the engine and the oil itself, so therefore, the coolant gives a significant balance in the removal of engine heat that is very essential in ensuring that the engine operates smoothly.
IMPORTANCE OF COOLANT
The heat that is generated during continuous combustion internally in engines can eventually destroy it and water alone cannot keep the cooling system working efficiently because the high temperature will boil and evaporate, and also during cold weather, if the engine is not in use the water will freeze making the cooling system not effective.
The combined action between the antifreeze (glycols) and water which makes up a coolant is what brings about the effective and efficient performance that a coolant exerts in different weather conditions at any given time. Also the presence of extra chemicals added to it such as corrosion inhibitors provides protection against corrosion and rusting.
Just like every other part in an automobile of any machine, it is important to maintain a cooling system. Coolant flushes are mostly recommended as it brings about many benefits and helps the system work efficiently.
Different engines come with different designs and models, this brings about variation in terms of maintenance. However, coolant flushes are always carried out once a year, but it is always advisable to check the user manual to know the various maintenance schedules, to know how they can be regulated and changed, also for selecting the right coolant for your engine.
At Gz supplies, we offer good quality antifreeze and engine coolants that will help your engine work effectively and protect it from high risk of damage.
