Toyota Long Life Coolant -40 C red (LLC) & Super Long Life Coolant SLLC) pink

Toyota declares : Despite the fact the red LLC and the pink SLLC are compatible and interchangeable, we do not recommend the replacement. Due to the fact that the LLC cannot be completely flashed out of the cooling system, the red LLC replacement intervals should be followed thus no tangible benefit would occur of such replacement. Additives such as amines, nitrites, silicates and borates are used in the red “Long Life Coolant”, whereas the pink “Super Long Life Coolant” has a non-amine, non-nitrite, non-silicate and non-borate additive formula.
