Introducing the New Nuke Performance Coolant Expansion Tank, 0.8L Performance

Nuke Performance launches the all-new Coolant Expansion Tank, 0.8L Performance - and matching Type-A Radiator Caps.

Gothenburg, Sweden, 2026-02-23
Nuke Performance, the Swedish motorsport parts manufacturer established in 2004, introduces its latest addition to the product portfolio – the 0.8L Performance Coolant Expansion Tank, together with a range of Type-A Radiator Caps, designed to improve cooling system stability in high-performance street builds and demanding motorsport environments.

Developed entirely in-house in Sweden, the new expansion tank features a lightweight aluminum construction and an oversized internal vortex chamber engineered to enhance coolant control and air separation efficiency. By optimizing deaeration and stabilizing system pressure, the design improves heat transfer and reduces the risk of localized boiling under sustained high load.

The matching 32mm Type-A Radiator Caps are available in multiple pressure ratings, allowing precise control of system pressure and coolant boiling point. Engineered for reliable opening characteristics and consistent pressure regulation, they ensure predictable performance in both performance street and professional motorsport applications.

Nuke Performance Coolant Expansion Tank, 0.8L Performance - engineered for stable pressure and maximum heat transfer.

Precision-built with a focus on durability, functionality, and clean integration, the new expansion tank supports higher system pressures and is fully compatible with Nuke Performance Type-A radiator caps. Together, they form a complete cooling system upgrade designed for modern high-output engines.

 Enhanced Deaeration thanks to the oversized Vortex chamber
 0.8L capacity aluminum dual-chamber design
 AN-6 ORB inlet and dual AN-10 ORB outlet ports
 Leak-free high-pressure operation with O-ring sealed body
 Type-A Radiator caps available between 1.1 to 2.0 BAR (16.0 - 29.0 PSI)

Trusted by race teams and performance enthusiasts worldwide, Nuke Performance continues to expand its product ecosystem by building complete systems – not just parts - and this is just the first of three coolant expansion tanks that will be launched during 2026, so much more is coming.

“The cooling system has not previously been part of the Nuke Performance ecosystem. With our new expansion tank and radiator caps, we set out to bring the same engineering, performance, and quality standards to a segment where too many solutions fall short. Our focus was not only on performance, but on long-term reliability under extreme conditions. And like all our products, they are designed and developed in Sweden for serious motorsport applications.” said Gustaf Brosten, CMD of Nuke Performance.

Designed and developed in Sweden, with no compromises in engineering, materials, or performance.
The Nuke Performance 0.8L Coolant Expansion Tank and Type-A Radiator Caps deliver the same uncompromising engineering standard as the rest of the Nuke Performance range. Developed for engines operating under high thermal stress, they improve cooling system stability and boiling-point control – critical factors in modern turbocharged and high-compression setups. All Nuke Performance products are proudly designed and developed in-house in Sweden, ensuring precision engineering and motorsport-proven reliability.
