PPE Silicone Upper and Lower Coolant Hose Kit 11-16 GM 6.6L Duramax
Description
Factory coolant hose "T" fittings in your 2011-2016 Duramax 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. 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" fitings 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 end is made from billet aluminum and 304 stainless steel. 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.
