Wehrli 01-06 Chevrolet 6.6L LB7/LLY/LBZ Duramax OEM Placement Coolant Tank Kit - Kiwi Green

This kit from Wehrli Custom Fabrication gives you a fabricated aluminum coolant tank, complete with a black anodized billet aluminum cap, mounting hardware, an overflow hose, and a low coolant sensor. It's designed to replace the factory plastic coolant reservoir in your 2001-2007 Chevrolet Silverado or GMC Sierra 2500 HD and 3500 HD trucks equipped with the 6.6L Duramax diesel engine, specifically the LB7, LLY, and LBZ models. This kit is a great way to dress up your engine bay and get rid of that often-cloudy plastic tank.

The tank itself is made from aluminum and features a durable custom powder coat finish in Kiwi Green, which not only looks sharp but also holds up well. A notable feature is the coolant level sight glass, making it easy to check your coolant level at a glance without needing to remove the cap. It also includes a low coolant level sensor, so your truck can alert you if the level gets too low, which is important for preventing engine damage. The cap is machined from billet aluminum and anodized black for a solid, premium feel and corrosion resistance. This kit is designed to mount in the OEM coolant tank location and uses the factory mounting points, meaning it will fit on stock trucks without requiring any other modifications. Installation is straightforward and can be done with basic hand tools.

Replacing the factory coolant tank is a popular upgrade for Duramax owners looking for a cleaner, more custom appearance under the hood. This Wehrli kit offers a well-built solution that addresses both aesthetics and functionality, ensuring your coolant system is visible and monitored. It directly replaces GM part numbers 15808714, 15290795, and 19353729.
