The GMC Sierra 3500 Upper Coolant Pipe by Wehrli is a top-tier component designed for the Duramax L5P 6.6L engine, spanning models from 2020 to 2025. Expertly crafted with functionality and durability at its core, this product not only replaces the standard OEM rubber upper radiator hose but does so with a striking gloss white powder-coated aluminum hard pipe for a robust and stylish upgrade.

This coolant pipe is engineered for a perfect fit in stock trucks without the need for modifications to your setup, ensuring a smooth and straightforward installation process using only basic hand tools. The aftermarket construction features a durable custom powder coat finish that enhances the cleanliness and organization of your engine bay while resisting corrosion and wear over time. This enhancement is specifically designed to complement vehicles still equipped with the OEM GM radiator, although compatibility with aftermarket radiators might vary.
