An antifreeze refers to a unique colored fluid that helps control the temperature in the engine. High-temperature surges can damage the engine system as it triggers the formation of oil deposits. Mechanics add this fluid to enhance the engine’s lifetime by thwarting corrosion.

5 Primary Qualities of High-Quality Engine Antifreeze

A suitable engine coolant must have particular characteristics such as:

  • Tolerant of hard water

A good cooling fluid should be usable with hard and soft water alike. Unfortunately, some engine fluids only mix well with soft water for heat regulation.

  • Relative heat transfer

Secondly, such a liquid should efficiently transfer heat within the radiator  to prevent the coolant from solidifying.

  • It must feature ethylene glycol.

Manufacturers make top-grade coolants from ethylene glycol to help reduce water’s freezing point. Similarly, this ingredient raises H2O’s boiling point to prevent it from vaporizing at relatively high temperatures.

  • Non-toxic

A reliable engine fluid should not contain corrosive substances as it will damage the radiator. Usually, the manufacturers make these fluids from ethane-1,2-diol as it is corrosion-resistant.

  • Low viscosity

An engine coolant must have low viscosity to transfer excessive heat more conveniently. A highly viscous fluid won’t have a turbulent flow, slowing down the rate of heat transfer.


What’s the Essence of an Approved Engine Antifreeze?

  • Prevents overheating

An engine coolant helps to dissipate excess heat further from the engine to ensure it operates properly. For this reason, it reduces the possibility of overheating as it can deform the engine pistons.

Usually, this coolant serves the same purpose as an intercooler, especially in diesel-powered engines.

  • Helps prevent rusting

A superb engine coolant can help safeguard the radiator against corrosion. However, this protection only applies if the radiator is made from other metals, excluding steel or iron.

  • For lubrication

An engine coolant acts as a lubricant for moving parts, such as the pump and the cylinder within an engine, to minimize friction. As a result, it helps to reduce wear and tear, ensuring the engine operates for a longer duration.

  • Impedes clogging

Gradual rust particle accumulation can trigger clogging in the radiator, preventing the engine from functioning well. However, cleaning services are essential to remove other particles from the engine system to allow sufficient airflow for combustion.

Closing Thoughts

A fuel-powered engine requires a functional antifreeze to regulate the temperature throughout when the car is running. Further, this tinted liquid also helps to make the cooling system rust proof.
