Two decades of heat cycling plastic components, such as your factory degas tank, will undoubtedly make them brittle and discolored. If your factory plastic degas tank is degrading, cracking, leaking, or you’re just sick of seeing that ugly yellow plastic, then look no further. The Mishimoto Aluminum Degas Tank for 2001-2007 Chevy/GMC 6.6L Duramax (LB7/LLY/LBZ) solves all these problems. Designed with durability and style in mind, the fully tig-welded aluminum construction ensures this will be the last time you need to replace your degas tank, and will spruce up your engine bay in the process. The available micro wrinkle black powdercoated finish is perfect for a clean, stealthy look. If you want something a little more flashy, the natural option is perfect for choosing your own finish by powder coating, anodizing, or hydro-dipping. The integrated internal baffles keep coolant near the overflow port during aggressive driving, preventing air entry into coolant system. The built-in sight glass makes it easy to check your coolant level, and the included coolant level sensor makes installation a simple plug-and-play. Avoid the hassle and mess of dealing with a broken, leaking degas tank with the Mishimoto Aluminum Degas Tank for 2001-2007 Chevy/GMC 6.6L Duramax (LB7/LLY/LBZ). As with all our products, this Aluminum Degas Tank includes our signature Mishimoto Lifetime Warranty.
