Mishimoto 01-07 Chevy/GMC 6.6L Duramax Degas Tank - Black

If you're working on a 2001-2007 Chevy or GMC truck with the 6.6L Duramax engine, you've probably seen how brittle and discolored the factory plastic degas tank can get after years of heat cycles. This Mishimoto aluminum degas tank is designed to solve those problems, offering a much more robust and cleaner-looking replacement. It's built tough to handle the demands of your diesel, whether you're just replacing a leaky tank or preparing for a single big turbo setup that needs extra space.

Constructed from fully TIG-welded aluminum, this tank is built to last, meaning you won't have to worry about it becoming brittle or cracking down the road. The micro-wrinkle black powder coat gives it a clean, stealthy appearance that spruces up the engine bay, but it's also ready for custom finishes if you want to personalize it further. Mishimoto specifically designed this tank to provide clearance for larger single turbochargers without needing any modifications or risking heat damage to the tank itself. Plus, the internal baffles help keep coolant near the overflow port during aggressive driving, which helps prevent air from getting into your cooling system.

Checking your coolant level is straightforward thanks to the integrated sight glass, and the included coolant level sensor makes installation a simple plug-and-play process, connecting directly to your factory wiring. This tank also offers a 55% increase in capacity over the stock unit, holding 0.65 gallons of coolant. It's a solid option for many Duramax applications, including Chevrolet Silverado and GMC Sierra 2500 HD and 3500 models, as well as Express and Savana vans from 2001-2007.
