Wehrli 01-05 Chevrolet Duramax LB7/LLY Upper Coolant Pipe - Candy Red

When you're working on the cooling system for your 2001-2005 Chevrolet Silverado 2500 HD or GMC Sierra 2500 HD with the Duramax LB7 or LLY engine, replacing the stock rubber upper radiator hose with a more robust aluminum pipe is a smart move. This aluminum coolant pipe from Wehrli Custom Fabrication is designed to directly replace the OEM rubber hose, offering a more solid and reliable connection for your coolant system.

Crafted from aluminum, this pipe is built to last and resist the heat and pressure that can degrade rubber over time. It comes with stainless steel T-bolt clamps and silicone boots to ensure a secure and leak-free seal. The candy red powder coat finish not only looks sharp under the hood but also adds an extra layer of protection against corrosion. This part is made in the USA, reflecting a commitment to solid construction.

This pipe is a direct replacement for GM part numbers 15792832 and 15198345, making the installation straightforward for anyone familiar with basic cooling system maintenance.
