Frequently Asked QuestionsWhat is Coolant and How Does it Work?Coolant, also known as antifreeze, is a liquid solution designed to regulate the temperature of your engine in extreme weather conditions. It works by absorbing and transferring heat away from the engine block and cylinder head, preventing overheating and damage. Coolant typically consists of a mixture of water and ethylene glycol or propylene glycol, with additives to prevent corrosion and improve performance. When the engine is running, the coolant circulates through the cooling system, absorbing heat and transferring it to the radiator, where it is dissipated into the air. This process helps to maintain a stable engine temperature, preventing damage and ensuring optimal performance. Does Coolant Lose its Effectiveness Over Time?Coolant does lose its effectiveness over time, but the rate of degradation depends on various factors, including the type of coolant, usage, and storage conditions. Generally, a high-quality coolant can last for up to 5 years or 150,000 miles, but it’s essential to check the coolant level and condition regularly. If the coolant becomes contaminated or degraded, it can lead to reduced performance, corrosion, and engine damage. It’s recommended to change the coolant every 30,000 to 50,000 miles or as specified by the manufacturer to maintain optimal performance and prevent issues. (See: Causes Coolant Hose Collapse) Why Should I Use a High-Quality Coolant?Using a high-quality coolant offers several benefits, including improved engine performance, reduced corrosion risk, and increased durability. High-quality coolants are designed to provide optimal heat transfer, corrosion protection, and freeze protection, ensuring that your engine runs smoothly and efficiently in extreme weather conditions. They also tend to last longer and provide better performance than lower-quality coolants, making them a worthwhile investment for any vehicle owner.
