This is a direct replacement coolant expansion tank for the 2012-2020 Chevrolet Sonic 1.4L and 1.8L. Simply remove your stock hoses, unbolt your coolant tank from the front of the engine bay, and swap everything over. This coolant tank features full aluminum construction with CNC brackets and cap provision, all powder coated wrinkle black. The tank uses a built in sight glass on the side to ensure proper coolant level. Fittings for your stock hoses are installed before shipping and the tank re-uses your stock cap.
