Coolant, commonly known as antifreeze, is an essential fluid used in vehicles and industrial machinery to regulate engine temperature and prevent freezing or boiling under extreme conditions. It is available in various concentrations, including 100% concentrate, 60%, 50%, and 33%, allowing users to tailor the mix according to climate and performance needs. A 100% concentrate provides maximum protection and flexibility, while the 50% concentration is the most common recommendation for balanced freeze and heat protection. The 60% and 33% blends cater to specific temperature ranges, ensuring optimal engine performance in different environments. Coolant is typically offered in a variety of sizes, from 1L for quick top-ups to larger containers like 20L, 25L, and 208L, making it suitable for both personal and commercial use. Proper maintenance of coolant levels is crucial for preventing engine damage, ensuring reliability, and extending the life of the vehicle.
