Overview
A swollen or leaking radiator hose on a 2011-2016 Chevrolet or GMC 6.6L Duramax LML can take a work truck down fast. This Mishimoto red silicone coolant hose kit replaces the aging upper and lower radiator hoses with five-layer silicone and a CNC-machined 6061 aluminum coupler that locks onto the factory radiator the same way the OEM quick-disconnect does.
Why silicone for an LML
Stock rubber softens with heat and oil mist. Mishimoto builds these hoses from high-grade silicone with five layers of heat-resistant fiber so they hold pressure and temperature better on stock and tuned trucks. The billet coupler mates the lower hose to the factory radiator without cutting, and the included T-bolt and worm-gear clamps keep the joints sealed under boost-related under-hood heat.
Features
- Direct fit for 2011-2016 Chevrolet/GMC 6.6L Duramax LML HD trucks
- Five-layer silicone construction for heat and pressure tolerance
- 6061 aluminum CNC coupler for the factory radiator quick-disconnect
- T-bolt and worm-gear clamps included
- Red finish (also available in black and blue on separate pages)
- Mishimoto Lifetime Warranty
What's Included
- 2 silicone radiator hoses
- 1 CNC aluminum coupler
- 4 T-bolt clamps
- 2 worm-gear clamps
- Mishimoto Lifetime Warranty
