What is a Coolant?

Coolants

Coolant is a fluid that flows through a vehicle’s engine block to keep the moving parts from becoming too hot. This can transfer the heat from the engine to the radiator which prevents the engine from overheating. It is made out of a substance called the glycol along with some other additives that prevent rust and is customarily mixed with water when in use.

 

These coolants contain properties that can prevent the fluid from freezing and this is commonly known as antifreeze. Antifreeze is a chemical additive that can lower the freezing point of a water-based liquid and the mixture is used to achieve freezing point depression for the cold environments as well as achieve the boiling point evaluation to allow higher coolant temperature. Therefore, it is important to check the levels of this vital fluid on a regular basis and monitor the system for leaks as well as change it.

 

When the engine runs, this can create a lot of heat from the combustion of fuel in the cylinders to provide power and this heat can be very harmful if it builds up. This can actually destroy the engine and the friction is created by the moving parts when there are high levels of heat and can cause parts to seize or change shapes.

 

This means that they can melt and stop completely. This engine coolant is a vital fluid for a vehicle to prevent overheating by absorbing excess heat and carrying it away to the radiator, this function can keep the coolant engine operating at a safe temperature.

 

Usually, coolant consists of ethylene glycol or propylene as its primary ingredient together with other substances called rust inhibitors which can prevent the cooling system parts and engine from rusting. This substance is usually mixed with water in the vehicle according to the manufacturer’s instructions. The ratio of the coolant to water is commonly 50-50 but sometimes other proportions are called if the vehicle operates in severe conditions.

 

Additionally, to keep the engine from overheating the glycol also can prevent the fluid from freezing in the winter so that the vehicle can operate in severe weather. The coolant is so important to the engine operation and it should be maintained properly. Besides, it is also important to check the coolant level on a regular basis.

 

This is very simple task to accomplish by looking at the side of the overflow tank which shows the appropriate levels when the engine is cold or hot.

 

If the fluid level is below the required amount, more fluid should be added to return to the necessary level and the system should also check for any leaks. Furthermore, antifreeze should be handled with extreme caution since both fluid types can be poisonous to animals and children. In order to keep the system operating as designed, the fluid needs to be replaced on a periodic basis as recommended by the manufacturer.
