Engine coolant or antifreeze, as it is commonly called, is the fluid that circulates within an automotive vehicle’s cooling system.
It serves several important functions to help maintain optimal engine temperature and performance:
1. Heat Transfer:
Additionally, engine coolant functions by taking heat from the engine through circulating in the cooling system, ensuring that the engine temperature does not rise too high.
2. Freeze Protection:
The coolant mixture has materials with low melting points that help to avoid the formation of strong ice in the badly designed coolant systems and the consequent freezing of the engine block and other metal elements in the automobile.
3. Boil Protection:
In the same manner antifreeze increase the boiling point of the liquid thus it can take higher degree’s of heat before the coolant boils and evaporates thus causing loss of coolant and consequent overheating of the engine.
4. Corrosion Prevention:
Engine coolant manufacturers add corrosion inhibitors to protect the numerous metallic parts of the cooling system against rusting and corrosion, thereby ensuring extended lifespans of the ancillary parts and maintaining the structural stability of the system.
5. Lubrication:
Some engine coolants have added lubricating properties, which allow them to further cuts friction and wearing on the engine cooling system making it work for a longer time.
6. pH Balance:
Coolant to regulate the pH of the coolant and avoid and excessive acidic or alkaline that might cause corrosion of the various parts and components of the engine.
7. Routine check:
The cooling system requires routine check on the levels of coolant, please the coolant and examining the coolants for any signs of leakage or other complications as described by the manufacturers and car experts.
The most prevalent types of engine coolants include those based on ethylene glycol and those based on propylene glycol, both of which have their own relative advantages and characteristics appropriate for use in various vehicles and varying weather and emission requirements.
