Wehrli 07.5-10 Chevrolet 6.6L LMM Duramax OEM Placement Coolant Tank Kit - Illusion Purple

If you're working on your 2007.5-2010 Chevrolet Silverado or GMC Sierra 2500/3500 HD with the 6.6L LMM Duramax engine, you might be looking to clean up the engine bay. This coolant tank kit from Wehrli Custom Fabrication is designed to replace that old, often yellowed or cracked plastic coolant reservoir with a sharp-looking, fabricated aluminum unit. It mounts right in the factory location, using the original mounting points, so you won't need to make any other modifications to your truck.

This kit isn't just about looks, though it certainly dresses up the engine bay with its durable Illusion Purple powder coat finish. The tank itself is made from aluminum, offering a more robust alternative to the stock plastic. You'll also get a low coolant level sensor to ensure your truck alerts you if the level gets too low, a billet aluminum cap with a black anodized finish, and an overflow hose. A billet aluminum sight glass is integrated into the tank, making it easy to check your coolant level at a glance without removing the cap.

Installation is straightforward and can be done with basic hand tools, making this a popular upgrade for Duramax owners looking to replace a worn-out reservoir or simply enhance the appearance of their engine compartment. This kit replaces GM part numbers like 15120611.
