2016+ CTS-V 1.5 Gallon Fender Expansion Tank
The Dedicated Motorsports coolant expansion tank for the 2016-2020 CTS-V adds 1.5 gallons of additional coolant capacity for the supercharger system. This additional volume will not only help maintain lower intake air temps, but it will also allow air to escape the system making the system more efficient overall. This tank also aids in filling/bleeding the system.
The DMS tank is constructed out of .125" aluminum, tig welded in house and powdered coated in a satin black finish. It features -12 ORB inlet/outlet fittings. Also included is premade -12an feed and return lines along with all hardware for trouble free installation. Install time is about 45 minutes.
