PPE Power Red Silicone Upper & Lower Coolant Hose Kit (2001-2005 GM 6.6L Duramax) - (119021100
Overview
Upgrade the cooling system on your early Duramax with the PPE Power Red Silicone Upper and Lower Coolant Hose Kit. This direct bolt-on replacement offers improved durability and reliability over the factory rubber hoses and plastic “T” fittings, making it a smart choice for both stock and modified 6.6L Duramax trucks.
High-Strength Silicone Construction
Each hose is manufactured from 5 mm thick premium silicone, providing nearly double the wall thickness of OEM hoses. Inside, 4-ply heat-resistant reinforcement fibers help the hoses maintain shape and integrity under high pressure and elevated coolant temperatures.
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 replaces these weak points with TIG-welded, polished 304 stainless steel “T” couplings that deliver exceptional strength 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, secure seal that outperforms standard OEM hardware.
Specialty W-Style Worm Drive Clamps
The included W-style inner liner clamps provide 360-degree constant tension with interlocking surfaces that help prevent leaks. Their stainless steel construction makes them highly resistant to moisture, chemicals, and engine-bay heat cycles.
