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

Coolant Reservoirs

Coolant Reservoirs

Coolant reservoirs, also called expansion tanks or overflow bottles, maintain a pressurized coolant supply that the radiator draws from as the cooling system cools down after engine-off. A cracked or leaking reservoir causes coolant loss and eventual overheating, while an upgraded billet or aluminum tank improves appearance and durability in performance engine bays.Popular UpgradesAluminum and billet coolant expansion tanks for LS and LT engine swaps and popular domestic performance vehicles are the most popular upgrades, providing a clean look and superior durability compared to factory plastic bottles that crack from heat cycling. Universal inline overflow tanks made from polished aluminum or anodized billet are popular on custom engine bays where the stock location has been eliminated. Direct-fit OEM-style replacement tanks restore coolant system function on high-mileage vehicles where the factory tank has cracked or the cap seat has deteriorated.How do I know if my coolant reser...
