🚗 What Does a Coolant Reservoir Do? - A coolant reservoir is a small plastic tank that is connected to the radiator of a car's cooling system. Its primary function is to provide a space for excess coolant to expand and contract as the engine heats up and cools down. Keep the engine operating at a normal temperature.
