Wehrli Custom Fabrication WCF100622-IBB Upper Coolant Pipe for 2006-2010 Duramax LBZ/LMM Illusion Blueberry

The Wehrli Custom Fabrication Upper Coolant Pipe is a high-performance direct replacement for the factory rubber upper coolant hose on 2006-2010 GM 6.6L Duramax LBZ/LMM engines. Manufactured from durable aluminum construction with beaded-rolled ends, this pipe offers superior longevity and heat resistance compared to the failure-prone OEM rubber hose.

Key Features:

• CNC-fabricated aluminum coolant pipe construction for maximum durability
• Custom two-stage Illusion Blueberry powder coat finish for show-quality appearance
• Beaded-rolled pipe ends ensure secure, leak-free connections
• Includes high-quality silicone boots for flexibility and heat resistance
• Complete with stainless steel T-bolt clamps for reliable installation
• Made in the USA with precision CNC machining and state-of-the-art fabrication
• Direct-fit replacement designed for use with OEM GM radiators

This complete kit includes everything needed for installation: the aluminum coolant pipe, silicone connection boots, and T-bolt clamps. The Illusion Blueberry finish provides a distinctive custom look under the hood while protecting against corrosion and wear. Note that some aftermarket radiators may cause fitment issues, so this pipe is designed specifically for OEM radiator applications.
