Product Description Reviews DMS ZL1 2 Gallon Supercharger Engine Bay Tank The Dedicated Motorsports coolant expansion tank for the 2012-2015 Camaro ZL1 adds 2 gallons 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 2" billet filler cap. This kit comes complete with all 3 hoses and hardware to make a breeze. General Dimensions: Height 14" Width 10.5" Depth 3.5" The DMS tank is constructed out of .125" aluminum, tig welded in house and powdered coated in a satin black finish. It features -12an (3/4 Inch) pushlock fittings, insulone hose and hardware for trouble free installation. Install time is about 45 minutes. For Roto-Fab or aftermarket intakes only, will not fit OEM airbox. **** Will not work with 2010-2011 SS Mechanical power steering**** 1 Review 5 DMS Tank and Manifold Posted by Blake Crawford on Jun 27th 2025 Awesome product, great finish. It was such a breeze to install. Took more time to unbox it then pull off old equipment and get the kit installed. I noticed about a 10-15° drop in IATs during multiple pulls at WOT. My ZL1 is now getting the CWA150 to push the additional 2-2.5 Gallons of Coolant.
