What is the color of the extended life radiator coolant recommended?

The color of extended life radiator coolant is typically light red. Extended life coolants are formulated with different additives designed to provide better protection against corrosion and rust for longer durations compared to conventional coolants. Light red coolant indicates that it uses organic acid technology (OAT), which allows for a much longer service interval.

This type of coolant is specifically designed to minimize the need for frequent changes and to enhance the performance and longevity of the engine cooling system. The specific color can help in distinguishing it from traditional coolants, which may be green or blue. It is important to use the correct type of coolant recommended by the vehicle manufacturer to ensure compatibility with the engine and cooling system components.
