In the realm of automotive maintenance, antifreeze, a crucial fluid known for its ability to prevent freezing during harsh winters and protect against boiling during sweltering summers, plays a pivotal role in ensuring optimal engine performance and longevity. Its composition, typically comprising ethylene glycol or propylene glycol, serves to lower the freezing point and raise the boiling point of water, thereby preventing catastrophic engine damage caused by extreme temperatures. Additionally, antifreeze contains corrosion inhibitors that protect metal components within the cooling system, extending their lifespan and ensuring reliable operation.
