Sinister Diesel 2011-2016 Duramax, Coolant Hose Kit (BLUE) – SD-HOSEKIT-DMAX-11


Product Highlights:

The Sinister Diesel Coolant Hose Kit for the 2011-2016 Duramax (LML) is a perfect way to ensure your cooling system is reliable for years to come. Factory hoses and T-Fittings are prone to cracking or failure, especially when pushed to their limits. Our Coolant Hose Kit is made from 4-ply heat resistant internal fibers and 5mm silicone, which is twice the thickness of factory hose. T-Fittings are TIG welded, 304 Stainless Steel to eliminate failure points. The quick-connect/disconnect end is made from billet aluminum and 304 Stainless Steel. T-Bolt clamps and worm-drive fasteners are used for a better than factory fit. Our hoses are finished in our Signature Sinister Blue.
