Fitment: 2013-2015 6.6L Duramax
Replace that cracked, leaky and boring factory coolant reservoir with the Sinister Diesel SD-DEGAS-LML-13 stylish and high-strength all-aluminum coolant reservoir. This Reservoir is made from 6061 aircraft-grade aluminum that is TIG welded and pressure tested for maximum strength. Best of all, the aluminum design helps to dissipate heat in the coolant system improving both performance and longevity.
This is a drop-in replacement for the factory coolant reservoir, so no modifications are required for this installation. Installing the coolant reservoir is quick and easy, and it can be installed with basic hand tools in less than 30 minutes even for a beginner. All of the installation hardware is included, and the sight glass allows for easy coolant level inspection. To top it off, it has been finished in Sinister Blue for a clean look under the hood.
