ZZPerformance is proud to offer the very first 100% aluminum radiator for the Cadillac ATS. GM has continued to use plastic end tanks on their radiators, and with time those end tanks will eventually crack and fail. This fully aluminum radiator will dissipate heat faster, looks better, and has more advanced cooling properties. Installs like factory, with no modifications needed. Re-uses stock fans and sensors, and transmission line fittings are included. 

Fits 2013-2016 ATS 2.0L, and 3.6L. Also fits 2014-2015 Cadillac CTS 2.0, and 3.6. May fit 2017-Present ATS, however we have not confirmed fitment. Will bolt up to 2.5 cars, however only the 2.5 has a provision for a coolant sensor that our radiator does not have.
