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.
