Chevrolet Silverado 3500 Upper Coolant Pipe – Wehrli – Sparkle Granny Smith – 2020–2025. This fabricated aluminum hard pipe replaces the factory rubber upper radiator hose.
Built for the 6.6L Duramax L5P in 2020–2025 Silverado or Sierra 2500/3500, this pipe uses the OEM GM radiator location for correct routing. The Sparkle Granny Smith powder coat is durable and tidies the bay, while silicone boots and stainless T-bolt clamps ensure secure connections. Installs with basic hand tools on stock trucks, no mods. Replaces GM 84813629 and 85122989. Note: designed for the OEM radiator; some aftermarket units may cause fitment issues.
