Nuke Performance 0.8L Coolant Expansion Tank

Nuke Performance Coolant Expansion Tank with oversized vortex chamber, for high-performance and motorsport applications.

The Nuke Performance 0.8L Coolant Expansion Tank is engineered for high-performance engines where coolant control, de-aeration, and durability are paramount.

• Improved de-aeration thanks to the oversized vortex chamber.
  
• Type A radiator cap compatibility.
  
• 0.8L capacity, aluminum dual-chamber design.
  
• AN-6 ORB inlet and dual AN-10 ORB outlets.
  
• Leak-free high-pressure operation thanks to its O-ring sealed body.

Crafted from lightweight materials. Made from solid aluminum and designed with an oversized vortex chamber, this high-performance expansion tank is designed to seamlessly integrate into the pressurized cooling system. It is designed to withstand extreme heat and pressure, while providing stable coolant circulation under demanding racing conditions. The oversized vortex chamber ensures improved de-aeration, the key to Nuke Performance's high-performance coolant tank design. The core of the design lies in the oversized vortex chamber. Incoming hot coolant is tangentially directed into the chamber through the AN-6 ORB inlet, initiating a rotational flow. The increased internal volume enhances air separation efficiency, stabilizes coolant circulation, and optimizes system performance compared to conventional designs. Internal dual-chamber design with oversized vortex chamber Designed to be part of the pressurized cooling system The tank features an internal dual-chamber design with controlled cross-flow channels, both at the top and bottom. This design allows for stable coolant movement, controlled air separation, and consistent pressure management within the pressurized system. Designed to be integrated into the pressurized cooling system, not as an overflow tank. The AN-6 ORB inlet port and the two AN-10 ORB outlet ports offer a wide range of connection options with our selection of fittings and adapters. An AN-6 ORB port located in the upper section serves as the inlet for hot coolant. Its positioning directs coolant directly into the vortex chamber to optimize rotational flow and air separation. We offer a wide range of AN-6 ORB fittings and adapters to suit your installation. AN-6 ORB inlet directing coolant to the vortex chamber. 6mm adapter for the radiator cap overflow port. Main AN-10 ORB outlet located below the vortex chamber. Two AN-10 ORB outlets are integrated into the bottom of the tank. The main outlet is located directly below the vortex chamber, and the secondary outlet is in the quiescent section for air purging or auxiliary return. This configuration ensures stable coolant circulation and effective system de-aeration, and is superior to simplified single-chamber coolant tanks with a single outlet port. Type A radiator cap compatibility, increasing system pressure and operating temperatures for high-performance and motorsport applications. The coolant tank uses a 32mm radiator neck, designed for use with standard "mini" Type A radiator caps. Upgrading to the Nuke Performance expansion tank allows the use of higher capacity Type A caps, increasing system pressure and operating temperatures for high-performance and motorsport applications. The indicated pressure rating represents the nominal release pressure and operates within a defined tolerance range. The illustration above shows the intended operating range for each Nuke Performance radiator cap. Cooling system pressure directly affects the coolant boiling point. Always select the lowest pressure cap that provides sufficient boiling margin for your application, as higher pressure increases thermal stability but also puts more stress on system components.
