PPE Power Black Silicone Upper & Lower Coolant Hose Kit (2001-2005 GM 6.6L Duramax) - (119020100
Overview
Refresh your early Duramax cooling system with the PPE Power Black Silicone Upper and Lower Coolant Hose Kit. This direct bolt-on upgrade replaces the factory rubber hoses and plastic “T” fittings with high-quality silicone and stainless components designed for long-term durability and improved coolant system reliability.
Heavy-Duty Silicone Construction
Each hose is built from 5 mm thick premium silicone, offering roughly twice the wall thickness of OEM hoses. Inside, 4-ply heat-resistant reinforcement fibers help the hoses maintain shape and strength under high pressure and elevated coolant temperatures - ideal for both stock and modified 6.6L Duramax trucks.
Upgraded Stainless Steel “T” Couplings
Factory coolant hose “T” fittings are molded rubber or plastic and are known to crack at the junctions over time. PPE eliminates this weak point by using TIG-welded, polished 304 stainless steel “T” couplings that provide exceptional durability and leak-free performance.
Direct Bolt-On Installation
This kit installs just like the factory components - no cutting or modifications required. PPE includes stainless steel clamps to ensure a tight, reliable seal that outperforms standard OEM hardware.
Specialty W-Style Worm Drive Clamps
Included in the kit are W-style inner liner clamps designed to maintain 360-degree tension and prevent leaks. Their interlocking surfaces and stainless steel construction make them highly resistant to moisture, chemicals, and engine-bay heat cycles.
