Wehrli 17-19 Chevrolet 6.6L L5P Duramax Upper Coolant Pipe - Illusion Purple

This Wehrli Custom Fab upper coolant pipe is what you get when you want to replace the factory rubber hose on your 2017-2019 Chevrolet Silverado 2500 HD or 3500 HD, or its GMC Sierra counterparts, with something more solid. It's designed to swap directly in place of the OEM rubber hose, which can sometimes degrade over time. By using aluminum for the pipe itself, you're getting a well-built component that's less prone to issues than the original rubber part.

This kit comes with the aluminum coolant pipe, which is finished in a durable Illusion Purple powder coat for a custom look under the hood. You also get silicone boots to connect the pipe to your radiator and engine, ensuring a good seal. To secure everything, stainless steel T-bolt clamps are included, offering strong and reliable fastening. This setup is a popular choice for L5P Duramax owners looking for a cleaner, more robust cooling system component.
