How Does Coolant Leak into the Engine?
The Importance of Coolant in an Engine
Coolant, also known as antifreeze, plays a vital role in an engine’s operation. Its primary function is to regulate the engine’s temperature by absorbing and transferring heat away from the engine block and cylinder head. This helps to prevent overheating, which can cause damage to the engine and its components. Coolant also contains additives that help to protect the engine from corrosion and wear.
There are two types of coolant: ethylene glycol and propylene glycol. Ethylene glycol is more commonly used in automotive applications due to its ability to provide better protection against corrosion. Propylene glycol, on the other hand, is used in applications where there is a risk of fire or explosion, such as in aircraft and marine engines.
