Keep your cooling system in check with the PPE Cab Side Heater Hoses for 2015-2016 GM 6.6L Duramax LML.
These heavy-duty silicone hose is a direct replacement for the factory heater inlet and outlet hoses that tend to harden and leak over time. Built with 1-ply heat-resistant Nomex fibers and 5mm thick silicone, it’s designed to handle the heat while providing long lasting durability.
Say goodbye to brittle, leaky hoses and keep your truck running at its best.
