Wehrli Custom Fabrication WCF100251-FTB Upper Coolant Pipe Fine Texture Black

The Wehrli Custom Fabrication WCF100251-FTB is an aluminum upper coolant pipe finished in Fine Texture Black powder coat, designed as a direct upgrade over the factory rubber upper coolant hose on 6.7L High Output (HO) Cummins diesel engines. Built from durable aluminum with beaded and rolled ends, this rigid hard pipe delivers a cleaner, more reliable cooling system connection compared to the OEM rubber hose it replaces.

Key Features:

• Fabricated aluminum upper coolant pipe construction for durability and long service life
• Fine Texture Black powder coat finish for corrosion resistance and a custom under-hood appearance
• Includes heavy-duty silicone boots for flexible end connections
• Includes T-bolt clamps for secure, leak-free installation
• Designed for High Output (HO) engine option only — compatible with the larger upgraded OEM RAM radiator
• For Standard Output (SO) engines, see WCF100223
• Replaces OEM MOPAR part numbers: 68359600AF, 68359600AD, 68359600AE

This upper coolant pipe is intended for use with the OEM RAM radiator. Note that aftermarket radiators may cause fitment issues. It is an ideal upgrade for High Output Cummins owners looking to eliminate the factory rubber hose with a rigid, professionally finished aluminum alternative.
