Westfield Header Tank

Pro-Alloy(motor Sport)

£298.67

Designed and created in-house to directly fit against the angled bulkhead found on Westfields. The first header tank was hand-built as a custom one-off design part for a customer who brought in his Westfield for a full cooling system overhaul! We ended up keeping the design drawings of the header tank to re-create the tank in future and offer to other Westfield owners! With a couple of slight revisions to the original one-off version, the one you see here features a 19mm return pipe as used most commonly on the Westfield’s and being the same port size as the commonly used plastic ford header t

Where this comes from

The part other shops don't tell you. Three separate questions, kept separate on purpose, each with its source.

UK company
Registered at Companies House as PRO-ALLOY(MOTOR SPORT)LIMITED, number 04988463. Checked 2026-08-29.
Means the business is a British legal entity, not a British-sounding name owned elsewhere. It says nothing about where anything is made.
UK operations
Not yet checked.
Means people employed here, or premises they actually work from. We keep this separate from the company badge because a registered office can be an accountant's spare room, and a company can be registered in Britain while everything it does happens somewhere else. Where we have not looked, we say so rather than assuming.
British-owned
Not established. Many companies file a statement rather than naming a controlling shareholder.
Read from the register of people with significant control, following the chain of holding companies. It does not gate anything: a firm can be made here and owned elsewhere, and that is worth telling you rather than hiding.
Where it is made
The maker doesn't say, so neither do we.
This is about the individual product, not the company. A British firm can sell things made abroad, which is normal and not a criticism. We would rather tell you which is which than average them into a score.
