Frequently Asked Questions
What is Engine Coolant, and Why is it Important?
Engine coolant, also known as antifreeze, is a liquid substance used to regulate the temperature of an engine in vehicles. It is a mixture of water and antifreeze agents, such as ethylene glycol or propylene glycol, which helps to prevent the engine from overheating or freezing in cold temperatures. Engine coolant is essential for maintaining the longevity and performance of an engine, as it helps to prevent damage from excessive heat or cold. Without engine coolant, an engine can overheat, causing damage to the engine, radiator, and other components.
How Does Engine Coolant Work?
Engine coolant works by circulating through the engine and radiator to absorb and dissipate heat. The coolant is pumped through the engine block, cylinder head, and radiator, where it is heated and cooled. As the coolant is heated, it expands and becomes less dense, which allows it to circulate more easily through the engine. When the coolant cools, it contracts and becomes more dense, allowing it to be pumped back through the engine to absorb more heat. The coolant’s ability to change viscosity with temperature makes it an effective heat transfer agent.
