The PPE 119020100 Silicone Upper & Lower Coolant Hose Kit replaces the worn or leaky factory coolant hoses in your 2001-2005 GM 6.6L Duramax LB7/LLY. The factory coolant hose “T” fittings are molded hose or made out of plastic and are prone to cracking at junctions, causing coolant loss. 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 Kit incorporates TIG welded, polished 304 stainless steel “T” fittings that eliminate any chance of failures at the “T” junctions. Durable 5mm thick silicone is twice as thick as the factory hose to ensure long-lasting performance. T-Bolt clamps and worm-drive fasteners 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.
