PPE Performance Silicone Upper and Lower Coolant Hose Kit; Orange (06-10 6.6L Duramax Silverado 3500 HD)Find parts that fit my vehicle

Factory coolant hose “T” fittings are molded hose or made out of plastic and are prone to cracking at junctions, causing coolant loss. Replace your worn or leaky factory coolant hose system with PPE’s Performance Silicone Coolant Hose Kit.

Perfect for your stock or highly modified Duramax 6.6L diesel truck. Engineered for performance and durability, featuring 4-ply heat-resistant internal fibers that provide strength against high-pressures and temperatures. PPE’s Silicone Coolant Hose Kits incorporate TIG welded, polished 304 stainless steel “T” fittings that eliminate any chance of failures at the “T” junctions. Durable 5 mm thick silicone is twice as thick as the factory hose to ensure long-lasting performance. The quick-connect/disconnect (LBZ, LMM, LML) end is made from billet aluminum and 304 stainless steel. Stainless steel clamps ensure a tight fit that performs better than factory.

The PPE Performance Silicone Coolant Hose Kit is a direct bolt-on upgrade that requires no cutting or modifications. Perfect factory fit with better-than-factory performance.
