Detailed Review
The Mishimoto MMHOSE-DMAX-11BL Silicone Radiator Hose Kit is a direct replacement cooling component engineered for 2011-2016 Chevrolet and GMC trucks equipped with the 6.6L Duramax LML engine. It is built to replace factory rubber cooling lines with durable, heat-tolerant silicone tailored specifically for heavy-duty truck platforms.
Constructed from high-grade silicone reinforced with embedded heat-resistant fibers, this kit manages temperatures up to 330°F. The kit features two distinct hoses sized to factory specifications. Hose 1 includes multiple inner diameter transitions measuring 0.58 inches, 0.71 inches, and 2.40 inches at the ends, paired with matching outer diameters from 0.96 to 2.80 inches. Hose 2 provides a uniform 1.77-inch inner diameter and a 2.10-inch outer diameter.
Because this kit is designed exclusively for the 2011+ Duramax LML platform, it will not fit older 6.6L engines or other truck configurations. Installation requires working with multi-diameter hose ends, and the package is limited strictly to the designated two-hose layout without extra clamps or hardware listed.
Verdict: This Mishimoto kit is an ideal choice for 2011-2016 Duramax LML owners needing a direct replacement hose set rated up to 330°F. Backed by a lifetime warranty, it provides exact-fit silicone construction for your truck cooling system.
