Replace brittle factory rubber coolant hoses on your 2011-2016 Chevrolet Silverado or GMC Sierra 2500 HD 3500 HD with the Mishimoto Duramax 6.6L LML silicone hose kit.

  • Complete OE Replacement Set: Includes all coolant hoses for thermostat radiator turbo intercooler and EGR systems with exact OEM routing bends for seamless swap
  • Stainless Steel Clamps: Constant-tension design secures hoses without over-tightening prevents leaks and corrosion for years of service
  • DuraCore Reinforcement: Multi-layer aramid fabric lining boosts durability against coolant abrasion and pressure spikes in 6.6L LML engines

Product Notes
