The Racer X Fabrication coolant neck for the 2012+ Chevy Sonic 1.4L, 2011+ Chevy Cruze 1.4L and 2015-2019 Chevy Trax 1.4L is a direct replacement for the OEM coolant neck. If you have ever found that you have become stranded in the middle of nowhere thanks to the trusty OEM coolant neck rupturing, you might want to consider upgrading to the Racer X cast aluminum coolant neck. We added a 1/8" NPT port which can be used with an aftermarket temperature gauge or plugged with the provided hardware.
