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

The Mishimoto degas tank provides a direct replacement degas tank for 01-07 Chevy and GMC trucks with the 6.6L Duramax, restoring cooling-system reliability by eliminating brittle, heat-aged factory plastic and preventing coolant loss from leaks.

This Mishimoto degas tank is engineered as a durable, long-lived substitute for the original plastic reservoir, addressing common failure modes after decades of heat cycling and discoloration.

Key technical points

• Direct replacement fit: Designed to match the OEM mounting points and hose connections for 01-07 Chevy/GMC 6.6L Duramax vehicles to simplify installation and restore factory routing.
• Improved material longevity: Replaces heat-cycled plastic that becomes brittle and discolored over time, reducing the risk of stress cracking and coolant leaks that compromise system pressure and reliability.
• Space for turbo upgrade planning: Frees up packaging compared with some OEM shapes, useful when planning turbo upgrade projects that require additional clearance in the engine bay.
• Brand reliability: Manufactured by Mishimoto, a supplier known for cooling-system components used in high-performance and motorsports applications.

Why this matters

Replacing a failing degas tank prevents coolant loss and air ingress, which can cause overheating and degraded system performance. The Mishimoto unit restores a dependable coolant reservoir volume and pressure control without the cosmetic issues of yellowed, brittle plastic.

For owners pursuing performance modifications, including turbo upgrade builds, installing a robust degas tank reduces the likelihood that the reservoir will be the weak link during increased thermal and mechanical stress.
