Wehrli 17-19 Chevrolet 6.6L L5P Duramax Upper Coolant Pipe - WCFab Grey

This aluminum coolant pipe from Wehrli Custom Fabrication is built for your 2017-2019 Chevrolet Silverado 2500 HD or 3500 HD, and GMC Sierra 2500 HD or 3500 HD with the 6.6L L5P Duramax engine. It directly replaces the factory rubber upper coolant hose, offering a more robust solution that's less prone to swelling or failure over time.

The pipe itself is constructed from aluminum, which is lighter than steel and won't degrade like rubber. It's finished with a durable WCFab Grey powder coat, adding a clean look under the hood and resisting corrosion. For a secure connection, it comes with stainless steel T-bolt clamps and silicone boots, ensuring a tight seal and reliable performance. This setup is designed to fit right, making the swap from the OEM part straightforward.
