Wehrli 17-19 Chevrolet 6.6L L5P Duramax Upper Coolant Pipe - Sparkle Granny Smith

This aluminum upper 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, which can degrade over time and lead to leaks. By swapping to a well-built aluminum pipe, you're adding a more robust component to your cooling system.

The pipe itself is constructed from aluminum, offering a solid upgrade over the stock rubber. It comes finished in a durable Sparkle Granny Smith powder coat, which not only looks sharp but also helps protect the aluminum. For a secure connection, it uses stainless steel T-bolt clamps and silicone boots, ensuring a tight seal and preventing leaks. This setup is designed to fit right, making the installation straightforward for those looking to improve the longevity of their cooling system.
