09D Header Tank [Fiesta ST Mk8/8.5 | Puma ST]

*Pre-Order Item: Order today, ships September*

Product Overview

Transform your Fiesta ST or Puma ST engine bay with the 09Design Aluminium Coolant Header Tank, a direct replacement for the standard plastic expansion tank that combines precision engineering, improved durability and unmistakable 09D styling.

Manufactured from billet aluminium using a two-piece design, the tank replaces one of the most visually prominent plastic components within the engine bay with a substantial, precision-machined alternative. Finished in anodised black, the intricate machined detailing across the upper section creates a distinctive technical appearance that complements the rest of the 09D engine bay range.

Unlike many aftermarket aluminium header tanks, we've also retained an easy way to check the coolant level. An integrated internal fill-level indicator uses a raised platform positioned directly beneath the filler neck, allowing the coolant level to be visually checked simply by removing the cap and looking into the tank.

Integrated Coolant Level Indicator

Integrated Coolant Level Indicator

Replacing the translucent factory coolant reservoir with an aluminium tank creates one obvious challenge - how do you check the coolant level?

Rather than accepting that compromise, the 09D Billet Aluminium Header Tank incorporates a dedicated fill-level indicator inside the tank.

Remove the coolant cap and look through the filler neck and you'll see a precisely positioned raised platform within the reservoir. This provides a visual reference for the correct coolant level, allowing routine checks to be carried out without the need for an external sight tube or window that would detract from the clean billet design.

It's a small detail, but exactly the sort of detail that matters.

Frequently Asked Questions (FAQs)

The factory expansion tank performs its job, but its translucent plastic construction can look out of place in a modified engine bay and can deteriorate and become brittle or discolour with age. The 09D tank replaces it with a precision-machined billet aluminium component designed to provide both a substantial upgrade in construction and a significantly more premium appearance.

With the engine completely cold, remove the coolant cap and look through the filler neck. The internal platform provides a clear visual reference for checking the coolant level without requiring an external sight tube or window.

The two-piece design allows us to create a much more complex internal and external structure than would be possible with a conventional fabricated tank, including the integrated coolant level indicator and detailed machining across the upper surface.

Yes. The tank is supplied with a bespoke 09D billet aluminium coolant cap, completing the design and providing a consistent finish across the entire assembly.

Yes. The tank has been designed as a direct replacement for the OEM expansion tank and incorporates the required connections for the vehicle's existing cooling system hoses.

The tank is designed around the vehicle's original mounting position and OE hose connections, making installation as straightforward as possible. As the vehicle's cooling system needs to be opened, however, installation should be carried out with the engine completely cold and the cooling system correctly topped-up and checked afterwards.
