Wehrli 17-19 Chevrolet 6.6L L5P Duramax Upper Coolant Pipe - Gloss White

Solve the factory coolant pipe failure problem on your 2017-2019 Chevrolet 6.6L L5P Duramax with the Wehrli Custom Fabrication Billet Aluminum Upper Coolant Pipe in Gloss White. The OEM plastic upper coolant pipe is a known weak point on the L5P Duramax that can crack, swell, and fail — causing coolant loss and potential overheating. The WCF direct-fit billet aluminum replacement eliminates this risk entirely.

Finished in a crisp Gloss White powder coat, the WCF100742-GW stands out in the engine bay with a clean, professional appearance. The billet aluminum construction is fully resistant to heat cycling, coolant chemistry, and underhood vibration, ensuring decades of reliable service.

Key Features

  • Fits 2017-2019 Chevrolet Silverado 2500/3500 with 6.6L L5P Duramax
  • Permanent billet aluminum replacement for the failure-prone factory plastic coolant pipe
  • Gloss White powder coat finish — corrosion-resistant and show-quality
  • Precision machined for OEM-correct fit and seal
  • Bolt-on installation, no modifications needed

MPN: WCF100742-GW
