The GMC Duramax Radiator Coolant Hose Kit by Mishimoto is engineered to enhance your vehicle's cooling system. Made from high-quality black silicone, these hoses are designed to withstand intense heat and pressure, ensuring your 2017-2019 6.6L L5P Duramax runs smoothly and efficiently.

This kit is a perfect replacement for the factory Duramax L5P radiator hoses, which can degrade and wear out over time due to heat cycles and high-stress use. Mishimoto's hoses boast a robust construction comprising five layers of silicone with heat-resistant embedded fibers. This design provides superior durability and performance even in the harshest conditions. The kit also replaces stock plastic connectors with durable aluminum junctions, offering increased resistance to heat and pressure. Along with the hoses, the package includes stainless-steel clamps and a new O-ring for the quick-disconnect fitting of the lower hose, ensuring a secure, leak-free installation. Additionally, this product comes with Mishimoto's Lifetime Warranty for added peace of mind.
