Wehrli 01-07 Duramax LB7/LLY/LBZ OEM Location Coolant Tank - Illusion Blueberry

This kit from Wehrli Custom Fabrication gives you a custom-finished aluminum coolant tank, 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 on 2001-2007 Chevrolet Silverado and GMC Sierra 2500 HD and 3500 HD trucks equipped with the 6.6L Duramax diesel engine, specifically the LB7, LLY, and LBZ engine codes. This setup mounts right where your original tank was, using the factory mounting points, so you won't need to modify anything else on your truck to install it.

You're getting a well-built aluminum tank that's powder-coated in a sharp Illusion Blueberry finish, which really helps dress up the engine bay compared to the standard clear plastic tank. It also features a coolant level sight glass, so you can easily check your coolant level at a glance without having to remove the cap. The included low coolant sensor will still function as intended, alerting you if the level gets too low. The cap is machined from billet aluminum and has a black anodized finish, adding another touch of custom detail.

Installation is straightforward and can be done with basic hand tools, making it a popular choice for Duramax owners looking to improve the appearance of their engine bay. This kit directly replaces GM part numbers 15808714, 15290795, and 19353729, ensuring a proper fit for the specified truck models.
