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.

Key Features

  • Fits 2017-2019 Chevrolet Silverado 2500/3500 with 6.6L L5P Duramax
  • Replaces OEM plastic upper coolant pipe with long-lasting billet aluminum
  • WCFab Red powder coat finish — bold underhood upgrade
  • Precision machined for perfect OEM fit and coolant system integrity
  • Simple bolt-on installation

MPN: WCF100742-RED
