Detailed Review
The EVIL ENERGY Upper Coolant Hose Kit replaces the stock factory rubber radiator pipe on 2020 through 2025 GM heavy-duty diesel trucks. Built around a solid aluminum pipe, it is designed for truck owners who want to upgrade their cooling system hardware and tidy up their engine bay for demanding driving and long-term ownership.
Installation is straightforward because the aluminum pipe follows the vehicle original routing path. You do not need to cut, trim, or modify any existing components to get a direct fit. The kit supplies everything required to complete the link, pairing the rigid aluminum pipe with 5-ply silicone couplers and heavy-duty T-bolt clamps for a tight, secure hold.
Beyond structural durability, this setup provides a cleaner, performance-inspired look under the hood. Swapping out the stock rubber upper hose for polished rigid tubing gives the engine compartment a more refined aesthetic while maintaining the factory coolant flow path.
Keep in mind that this kit is built strictly for 2020 to 2025 Chevrolet Silverado and GMC Sierra 2500HD and 3500HD trucks equipped with the 6.6L L5P Duramax diesel engine. It is not compatible with other engine platforms or older model years, and it addresses only the upper cooling connection rather than the full cooling system.
Verdict: If you own a 2020-2025 L5P Duramax and want a durable, direct-fit upper coolant pipe upgrade that enhances your engine bay appearance, this complete kit is an excellent choice.
