DMS V3 Engine Bay Tank

The Dedicated Motorsports coolant expansion tank for the 2016-2019 CTS-V adds just under 1 gallon of additional coolant capacity. This additional volume will not only help keep intake air temps lower 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 thanks to the 1.5" billet filler cap.

The DMS tank is constructed out of .125" aluminum, tig welded in house and powdered coated in a satin black finish. It features 3/4 inch inlet/outlet barbs and includes all hose, clamps and hardware for trouble free installation. Install time is about 30 minutes.
