Our 2005 Toyota Corolla had its engine cooling system filled with pink Toyota SLLC (Super Long Life Coolant) at the factory that doesn’t need to be replaced for ten years or 100,000 miles. For some extra peace of mind, I decided to change out most of the coolant by draining and refilling the radiator after just 6 years and 85,000 miles.
