Mishimoto Aluminum Degas Tank Fits Chevy/GMC 6.6L Duramax LB7/LLY/LBZ 2001-2007 Natural

The Mishimoto aluminum degas tank in natural finish replaces brittle factory plastic coolant reservoirs on 2001-2007 Chevy and GMC trucks equipped with 6.6L Duramax diesel engines LB7 LLY LBZ. This direct-fit part boosts coolant capacity by 55% to 0.65 gallons provides clearance for single big turbo setups and features TIG-welded aluminum construction for long-term reliability. Internal baffles maintain coolant flow during hard driving while sight glass and included sensor simplify level checks.

Key Features

  • 55% Capacity Increase: Holds 0.65 gallons versus stock for better cooling reserve during high-heat performance driving
  • TIG-Welded Aluminum Build: Resists cracking discoloration and leaks from years of heat cycling unlike factory plastic
  • Big Turbo Clearance: Engineered spacing fits single turbo applications without trimming or meltdown risk
  • Internal Baffles: Direct coolant to overflow port under aggressive conditions to block air from entering the system
  • Sight Glass and Sensor: Quick visual level checks with OEM-style plug-and-play sensor for easy install

Product Notes

  • Natural finish supports custom powder coating anodizing or hydro-dipping services sourced independently
  • Surface imperfections on natural finish do not impact performance or customization adhesion
  • Verify coolant level via sight glass after initial heating and cooling cycles

Installation Notes

  • Professional installation recommended.
  • Direct bolt-on replacement with plug-and-play coolant level sensor
  • Compatible with factory radiator cap no additional hardware required
