Car coolant, also known as antifreeze, serves several critical functions in a vehicle's engine:
- Temperature Regulation: Coolant circulates through the engine and radiator, absorbing excess heat generated by the engine and dissipating it into the air. This process keeps the engine at a stable, optimal temperature, preventing overheating which can cause severe engine damage or even melting of components
- Antifreeze Protection: It prevents the coolant from freezing in cold temperatures, which protects the engine's internal parts from cracking due to ice expansion. This ensures the engine operates reliably in cold climates
- Lubrication: Coolant lubricates moving parts it contacts, such as the water pump, head gasket, and cylinder components, reducing wear and preventing damage
- Corrosion and Scale Prevention: The coolant contains additives that reduce corrosion and scale buildup inside the engine and radiator, protecting metal and rubber components from damage and extending their lifespan
- Heat Transfer Medium: It works with the vehicle’s liquid cooling system components (water pump, radiator, hoses, fan, thermostat) to efficiently transfer heat away from the engine, maintaining performance and preventing engine failure due to heat-related issues
In summary, engine coolant is essential for keeping the engine cool, preventing freezing, lubricating parts, and protecting against corrosion, all of which help maintain the engine’s performance and longevity
