Coolant, also known as antifreeze, plays a crucial role in maintaining the health and efficiency of your vehicle’s cooling system. Here’s a closer look at what coolant does and why it’s essential:
Heat Transfer: The primary function of coolant is to absorb heat from the engine and transfer it to the radiator, where it can be dissipated into the air. This process regulates the engine’s temperature and prevents overheating, especially during periods of heavy use or high temperatures.
Freezing and Boiling Point Protection: Coolant contains additives that lower its freezing point and raise its boiling point, making it suitable for use in a wide range of temperatures. This property is essential where freezing coolant could damage the engine, and where high temperatures could cause coolant to boil and evaporate.
Corrosion Prevention: Modern coolants contain corrosion inhibitors that protect the metal components of the cooling system from rust and corrosion. This maintains the longevity of components such as the radiator, water pump, and heater core.
Lubrication: Coolant also provides lubrication to the water pump, helping it operate smoothly and efficiently. Proper lubrication reduces friction and wear on the pump’s moving parts, extending its lifespan and preventing premature failure.
Seal Conditioner: Some coolants contain seal conditioners that keep gaskets and seals pliable and prevent leaks. This is especially important in older vehicles with rubber seals that may deteriorate over time.
Compatibility with Materials: Coolant is formulated to be compatible with the various materials used in modern cooling systems, such as aluminum, copper, and plastic. Using the wrong type of coolant can lead to corrosion and damage to these components.
Regular inspection and maintenance of your vehicle’s cooling system, including periodic coolant flushes and replenishments, ensure optimal performance and longevity. Consult your owner’s manual or a qualified mechanic to determine the correct type of coolant for your vehicle and the recommended maintenance schedule.
