Dedicated Motorsports 6 Gallon Trunk Tank (76108000050) - 2016-2019 Cadillac CTS-V
The DMS Trunk Tank is designed to combat the heat generated by superchargers on the 2016-2019 Cadillac CTS?V. Adding just over 6 gallons of coolant capacity, this trunk?mounted ice box improves cooling efficiency and provides a simple way to ice down the system before each run. To maximize space, the tank is positioned in place of the passenger?side plastic cubby.
Construction & Design
Each tank is precision laser?cut from 1/8" 5052 aluminum, formed, and hand TIG?welded for strength. Standard features include a 5" billet lid for easy filling, 3/4" feed and return lines, and a Pierburg CWA?100?3 pump working alongside the OEM coolant pump. Testing showed an additional 1.5 gallons per minute of flow when retaining the factory pump. Installation is streamlined, requiring minimal drilling thanks to an integrated drain valve in the pump feed line.
