Wehrli 01-07 Duramax LB7/LLY/LBZ OEM Placement Coolant Tank - Bronze Chrome

If you're looking to clean up the engine bay on your 2001-2007 Duramax LB7, LLY, or LBZ truck, replacing that bulky, often cloudy plastic coolant reservoir is a great place to start. This fabricated aluminum coolant tank from Wehrli Custom Fabrication is designed to mount right in the factory location, making the swap straightforward. It’s a solid option for anyone who wants their Duramax to look as good as it runs, especially if you’ve already upgraded other parts of your cooling system or engine bay.

This tank isn't just about looks, though. It's built from aluminum and features a durable bronze chrome powder coat finish that holds up well over time. A key feature is the integrated coolant level sight glass, which lets you quickly check your coolant level without having to remove the cap. It also includes a low coolant level sensor to alert you if the level drops too low, along with a black anodized billet aluminum cap and the necessary overflow hose and mounting hardware. This kit is designed to fit directly onto your truck using the OEM mounting points, meaning no complex modifications are needed for installation.

When you're ready to install, you'll find it uses basic hand tools and bolts right up. This Wehrli coolant tank is a well-built replacement for GM part numbers 15808714, 15290795, and 19353729, offering a significant visual improvement and practical functionality over the stock plastic tank. It's a popular choice for Duramax owners looking to add a custom touch to their engine bay while maintaining reliable coolant system monitoring.
