The final piece of the Sonic coolant system overhaul is now available from ZZPerformance. The 1.4 Sonic's coolant system is one of the most flawed from the factory that we've seen in a long time. Plastic parts, high coolant temperatures, and penny pinching means that there are 3 essential items that need to be replaced. The driver's side coolant outlet, thermostat housing, and coolant tank are the 3 most replaced items in the system. The stock parts will crack from heat cycling and time and can cause your car to overheat if enough coolant is lost. When you upgrade to our ZZP aluminum versions of each you can ensure your coolant system remains leak free all while looking great under the hood. 

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. 

Fits: 2012-2020 Chevrolet Sonic 1.4L and 1.8L. Does not fit Chevy Cruze.
