Direct replacement aluminium header tank expansion reservoir for Defender, Discovery and Range Rover

Supplied with our lifetime warranty*

Designed and built in our Herefordshire workshops to replace the original plastic item which is prone to splitting along the seam caused by heat cycling.

This design eliminates the problem and also aids cooling.

Manufactured from high grade corrosion resistant 2mm aluminium, laser cut, CNC folded and fully TIG welded by hand in house.

Uses the original mounts and hose connections. CNC machined pipe connections for extra pipe security.

Supplied as standard with plastic pressure cap, we also offer a range of aluminium caps.

Various options available – with sight gauge, low level float switch and powder coated black

Suitable for models with level switch integrated into the cap such as Range Rover Classic

Can be made to fit earlier models with “lozenge” shape metal tank with minor modifications to the pipe connections and mounting system.

*Lifetime warranty excludes cap and float switch

    A great looking tank for under the hood of the Defender. Sight gauge adds to the look. Fantastic welds.

    Nice and functional

  10. Knud (verified owner)

    Für den V8 muss man einen Anschluss verschließen, sonst sehr chic

  11. Steve Pickering (verified owner)

    My engine bay is really starting to look like a jewellery box thanks to all your hard work (and little bit of my polishing abilities), just need a few finishing touches once the supplier problems are sorted and the engine portion of the project will nearing completion- thanks to all at Allisport !

  12. Ignazio (verified owner)

    For me it was a very important purchase, the old plastic tank exploded, causing considerable damage to the cylinder head of my 300Tdi. I chose the one with the visual indicator and the minimum level switch. All owners of Discovery I or Defender with plastic tank should replace it with this product, to avoid the same problems I had. Excellent build quality as for every Allisport product, previously I bought the XL radiator and full size intercooler, the best on the market.

  13. grant (verified owner)

    Top quality replacement for the plastic prone to splitting tank.

  14. Rob Adams (verified owner)

    Absolutely love this and the cyclone separator. Both much better than the plastic originals in looks and function. Wish I had bought the version with the gauge on the side but that’s hindsight for you

  15. David (verified owner)

    Great quality and the sight gauge saves a lot of time. I have added a level alarm but wish I had gone with their product built in. Will be buying for my other landie!

  16. Simon grindrod (verified owner)

    Well built , well designed.
    Form And function!
    Enhances the engine bay

  17. Pete (verified owner)

    The best Function and beauty can be yours

  18. Simon (verified owner)

    Excellent quality product as usual from AlliSport. Fast delivery, well packed.
