Wehrli 17-19 Chevrolet 6.6L L5P Duramax Upper Coolant Pipe - WCFab Red
Replace the failure-prone factory upper coolant pipe on your 2017-2019 Chevrolet 6.6L L5P Duramax with the Wehrli Custom Fabrication Billet Aluminum Upper Coolant Pipe in bold WCFab Red. The stock plastic coolant pipe is a widely documented weak spot on the L5P Duramax platform — prone to cracking and swelling over time. The WCF billet unit is a permanent fix designed to outlast the truck itself.
The WCF100742-RED is finished in Wehrli's signature WCFab Red powder coat for a high-visibility, performance-shop look that sets your engine bay apart. Precision-machined to match factory dimensions for a leak-free, hassle-free installation.
