Vehicle coolant warning light returning to normal indicates slight coolant deficiency. During driving, fluid level fluctuations may trigger intermittent warning signals. Promptly visit a repair station for coolant replenishment. Below are detailed explanations about automotive engine coolant: 1. Overview: Coolant, also called antifreeze or radiator fluid, primarily ensures proper engine operation by circulating through the radiator to provide freeze protection, boil prevention, rust inhibition, and corrosion resistance. 2. Additional Information: Typically colored red or green for leak detection, most engine coolants are ethylene glycol aqueous solutions.
