Nuke Performance Coolant Expansion Tank, 1.0L - 455-01-201

The Nuke Performance Coolant Expansion Tank, 1.0L is a lightweight aluminum coolant expansion tank designed for both street and motorsports applications where dependable cooling system performance, durability, and ease of installation are essential.

Featuring a straightforward single-chamber design, the 1.0L expansion tank provides a robust and lightweight solution for pressurized cooling systems. Its side-mounted AN-8 ORB inlet introduces coolant with a controlled swirling motion, supporting consistent circulation and natural air separation within the tank.

The tank is designed to function as an integrated component of a pressurized cooling system rather than as a conventional overflow tank. Built to withstand demanding heat and pressure conditions, it provides stable coolant flow and reliable long-term performance across a wide range of street and motorsports applications.

Simplified Single-Chamber Design with Controlled Vortex Inlet Flow

The Nuke Performance 1.0L Coolant Expansion Tank uses a straightforward single-chamber internal layout designed to provide reliable coolant management across a wide range of applications.

Incoming coolant enters through the side-mounted AN-8 ORB inlet, creating a controlled swirling motion inside the tank. This inlet flow helps promote consistent coolant circulation and natural air separation while maintaining predictable system behavior.

The simplified internal construction provides a reliable and efficient solution for pressurized cooling systems without the added complexity of a multi-chamber design.

The expansion tank is engineered to function as an integrated component of the pressurized cooling system and is not designed to serve as an overflow tank.

For applications requiring more advanced internal flow and deaeration engineering, the Nuke Performance 0.8L Performance Coolant Expansion Tank features an oversized Vortex chamber and a dual-chamber internal design.

AN-8 ORB Inlet and AN-10 ORB Outlet

The upper side-mounted AN-8 ORB inlet serves as the entry point for incoming hot coolant. Its position introduces coolant into the tank with a controlled swirl, supporting consistent circulation and natural air separation.

The tank features a single AN-10 ORB outlet positioned at the bottom of the expansion tank. This outlet serves as the primary coolant return and supports stable coolant circulation within the pressurized cooling system.

The straightforward AN-8 ORB inlet and AN-10 ORB outlet configuration provides flexibility for different hose routing and installation requirements while maintaining a simple and reliable plumbing arrangement.

Type-A Radiator Cap Compatibility

The Nuke Performance Coolant Expansion Tank uses a 32mm radiator neck designed for standard mini Type-A radiator caps.

The Type-A radiator cap system allows the cooling system to use different pressure ratings depending on the requirements of the application. Higher-rated radiator caps can increase system pressure and raise the coolant boiling point, making them suitable for certain high-performance and motorsports applications.

Available Type-A radiator cap pressure ratings include:

• 1.1 BAR (16.0 PSI), Part # 452-01-011
• 1.3 BAR (18.9 PSI), Part # 452-01-013
• 1.5 BAR (21.8 PSI), Part # 452-01-015
• 2.0 BAR (29.0 PSI), Part # 452-01-020

The stated pressure rating represents the nominal release pressure and operates within a defined tolerance range.

Cooling system pressure directly affects the coolant boiling point. Always select the lowest pressure radiator cap that provides sufficient boiling margin for the specific application. While higher pressure can improve thermal stability, it also places greater stress on cooling system components.

Designed for Street and Motorsports Applications

The Nuke Performance Coolant Expansion Tank 1.0L provides a balanced combination of lightweight construction, simple installation, and reliable cooling system functionality.

Its single-chamber construction and controlled inlet flow make it suitable for a wide range of applications where a compact and dependable pressurized coolant expansion tank is required.

The tank is designed and developed in Sweden with a focus on function, fit, reliability, and durability. Its welded aluminum construction is engineered to provide consistent performance under demanding operating conditions, including high-temperature and motorsports environments.
