What color is extended life coolant, which includes OAT or NOAT?

Extended life coolant that uses Organic Acid Technology (OAT) or Non-OAT (NOAT) is typically identified by its red color. This color coding is part of a system that helps identify the type of coolant and its properties. Red extended life coolants are designed to provide superior protection against corrosion and have a longer service life compared to traditional coolants, which are often colored green.

The formulation of OAT and NOAT coolants includes organic acids that effectively inhibit rust and corrosion in both the engine and the cooling system. The red color is an industry-standard indicator that helps mechanics and technicians ensure they are using the correct type of coolant for vehicles that require extended life coolant, improving heating and cooling efficiency while minimizing maintenance and repairs.

Understanding the color coding of coolants is essential for proper vehicle maintenance, as using the wrong type of coolant can lead to engine damage or reduced performance over time.
