The PPE 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.
PPEs 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.
