  1. Steel Henderson (verified owner)

    You guys are awesome. How the hell, my item shipped from you guys in the UK to the west coast of the US in 3 days. The welds are gorgeous btw.

  2. jvatovec (verified owner)

    The quality and craftsmanship of this Tank is truly Bespoke. The welds were made by someone I can only describe as a welding artisan. My 2004 Discovery has over 130k miles and I have 2 plastic OEM tanks develop cracks. This tank looks like the end-all solution for the weak plastic. Jason USA

  3. Matt knight (verified owner)

    Expensive yes but quality comes at a price beautiful product and finally an end to my problems with cracking header tanks superb highly recommended

  4. Feroz (verified owner)

    Great product.. perfect fit.

  5. Yaron geva (verified owner)

    Excellent didn’t miss a drop of water since I got it

  6. Phillip Bussey (verified owner)

    Might be a bit more expensive than a OEM plastic one but at least this one won’t split after 2 years ( I hope ).Looks amazing such a shame to hide it under the bonnet. My only slight issue was the fit of the locating lugs allows the tank to move and rattle slightly.

      Thank you for your feedback, great to hear you are pleased with the product! There should be supplied with the tank some small strips of rubber to stop the tank moving. Let me know if they are missing from the package. Andrew

  7. Jason Hiler (verified owner)

    Very well made tank. Fits and looks great. Far superior to OE plastic tanks. Because of supply issues mine did not come with the “engraved Allisport pressure cap” that is mentioned in the description. The pressure cap they supplied does leak a little so looking forward to getting the Allisport cap.

  8. Lon Coggeshall (verified owner)

    Cap came unglued on the first day of use, luckily the cap is two pieces and the part that seals stayed in place. Maybe they should use a better glue or perhaps a spot weld? Other than that, it looks cool.

    • Andrew Graham

      Thank you for the feedback, it is appreciated. We have recently revised the cap design to stop this happening in the future.

  9. Samantha L (verified owner)

    The cap came off when I carried it upside down. It isn’t the sealed cap but a facade on top of it. For the price and the fact I’m in Canada and the shipping cost isn’t worth sending it back, I was disappointed. I’m hoping that there aren’t any other issues with the product as I have yet to complete the change out of my coolant system. I also didn’t receive the rubber strips to prevent rattling. Just a bumper sticker.
    The welds are beautiful s is the reservoir. I chose the one with the visual gauge which also is stunning.

    • Andrew Graham

      Thank you for your feedback Samantha, we have taken note and revised the cap design. We will happily supply a replacement cap and fitting rubbers at our cost

  10. John Coulthard (verified owner)

    The fabrication standard and welding quality is second to none. Finishes off the engine bay beautifully and removes the achilles heel of the OEM unit that can split at the circumferential seam.

  11. David Sullivan (verified owner)

    This gear is second to none. I have their intercooler, radiator and now the coolant fill tank. I plan to also get their power steering/ace tank as well.
    The fact that I have got all these products says it all. Top company with excellent products.

  12. Liam Price (verified owner)

    This is the expansion tank every Discovery 2 owner needs, I went through 6 genuine expansion tanks that Land Rover Australia continuously replaced under warranty through my local dealer and each tank developed a hair line crack which would continue to crack over time.

    I was so close to calling it quits and selling the car, this tank was the last resort and I’m so glad I made the decision.

    Build quality is perfect, it looks great and I’ve had no reason to question durability, it will last the test of time.

    I will be switching to Allisport products from now when replacing components on my 2004 TD5 Discovery 2.

  13. Chris Baker (verified owner)

    Great replacement for a flawed factory design on the P38 and Discovery 2 models. I’ve had no concerns of rapid system depressurization with this unit in place- (happened to me twice with the old plastic tanks on my 2002 P38 while on the road!). Great product from Allisport that looks as good as it performs

  14. Chance shambaugh (verified owner)

    Amazing product at a great price, I’ve got the d2 header tank with the sight glass an so far so good. no leaks and the welding is beautiful on it. really happy and highly recommend.
