Upgrade Your Cooling System with Style and Strength

If you’re looking to clean up your engine bay while adding durability to your cooling system, the Wehrli 100622 Upper Coolant Pipe is the perfect fit for your 2006–2010 Silverado or Sierra 2500HD/3500HD with the 6.6L Duramax LBZ or LMM engine. This aluminum pipe replaces the factory rubber upper coolant hose, eliminating a common weak point that can crack or leak over time. Along with the pipe, you’ll receive high-quality silicone boots and T-bolt clamps for a secure, leak-free installation. To top it off, Wehrli powder coats each pipe in your choice of color, adding a custom look that stands out without sacrificing function.

Durable Construction for Everyday and Performance Builds

Built to last, this upgrade not only looks good but also performs under the demands of towing, hauling, and high-performance driving. Unlike the flexible rubber hose that comes from the factory, this rigid aluminum pipe resists heat, pressure, and deterioration, giving you long-term peace of mind. Installation is straightforward, requiring no modifications, making it a great weekend project whether you’re refreshing your cooling system or adding finishing touches to your engine bay. Please note that, unlike some other Wehrli products, this pipe does not include the WCFab badge, but it still delivers the same trusted quality and performance you expect.
