Detailed Review
The EVILENERGY Upper Coolant Hose Kit replaces the factory upper radiator hose on 2011-2016 Chevrolet Silverado and GMC Sierra heavy-duty trucks. Built for trucks with the 6.6L LML Duramax diesel engine, it swaps out standard rubber tubing for a rigid aluminum pipe setup designed for dependable everyday driving and demanding use.
Installation is straightforward because the aluminum pipe follows the original factory routing path. It serves as a direct replacement without requiring any cutting or vehicle modifications. The kit comes complete with 5-ply silicone couplers and T-bolt clamps, providing all the necessary hardware to form a tight, secure upper coolant connection right out of the box.
Beyond functional cooling connectivity, this kit serves as an under-hood visual upgrade. Replacing the flexible stock rubber hose with a clean aluminum pipe delivers a more refined and organized look in the engine bay, making it a popular choice for owners working on custom builds or seeking a cleaner appearance.
Because this is a vehicle-specific kit, its main limitation is compatibility. It only fits 2011-2016 2500HD and 3500HD models equipped with the 6.6L LML Duramax, and it only addresses the upper radiator connection rather than the full cooling system.
Verdict: This upper coolant kit is a smart choice for 2011-2016 LML Duramax owners who want to upgrade their factory rubber upper radiator hose to a sturdy aluminum and silicone setup with direct-fit convenience.
