Upgrade your 2001-2007 GM 6.6L Duramax LB7/LLY/LBZ with the Mishimoto MMRT-DMAX-01MWBK Aluminum Degas Tank, an ideal replacement for your old, cracked factory unit. Over time, the heat-cycling of plastic components like your OEM degas tank can lead to them becoming brittle, discolored, and eventually leaking. If you're seeking to replace a leaky tank, are done with the unsightly yellow plastic of the stock unit, or are moving to a single big turbo setup, Mishimoto has engineered the perfect solution.

• Compatibility: Designed specifically for 2001-2007 GM 6.6L Duramax engines, ensuring a seamless fit.
• Construction: Features full-aluminum construction with precision TIG-welds for unmatched durability and longevity.
• Design: The micro-wrinkle black powder-coated finish offers a clean, stealthy look that enhances engine bay aesthetics.
• Functionality: Internal baffles keep coolant near the overflow port during dynamic driving, preventing air from entering the cooling system. A sight glass allows for easy monitoring of coolant levels, and the included fluid level sensor ensures accurate reading for trouble-free installation.
• Capacity Increase: Expands coolant capacity by 55%, holding up to 0.65-gallons, to better accommodate high-performance demands.
• Turbo Clearance: Provides ample clearance for single turbo applications without requiring any trimming, eliminating concerns about heat damage.

The Mishimoto Aluminum Degas Tank is not just a replacement part; it's an upgrade for your engine's performance and appearance. With its durable construction and thoughtful engineering, it addresses common issues with stock tanks while providing significant improvements in both function and form. Installation is made simple with the inclusion of an OEM-quality fluid level sensor, and the tank's design ensures compatibility with big turbo setups without modifications.

Please Note: Mishimoto recommends checking the coolant level via the sight glass after several heating and cooling cycles to ensure proper coolant level maintenance. It is important to note that Mishimoto does not offer powder coating, anodizing, or hydro-dipping services for this product. Customers who choose the natural finish should be aware that surface imperfections may be present but will not affect further customization processes.
