HYPER-SEAL ULTRA SEALS AS STEEL - HEAVIEST HEAD GASKET LEAKS REPAIR

Great product. Used as per tin instructions

Unfortunately for my car the item didn’t work. However, I complained to the seller and they answered me promptly.

I used it on my tractor and wasn't sure if it would work but I thought I would give it a try, I used it as instructed on the tin and it worked perfectly, I am pleased I will defiantly use it again,

i am not a hobby mechanic bought this cause cheap price but paid in kind,first of all seller listing does not have detailed instructions l am pretty sure thats on purpose but what l dont like about this product is it does not work or should not be used with anti freeze that means draining all coolant in my case l had to flush 4 times from radiator drain plug didnt want to drain from block too tedious so l bought loads of distilled water,the other instruction for any engine with back pressure is remove spark plug and run whole process without it,l bought to use on bmw 5 series e39 and always need fan blower on when bleeding but this isnt recommended for this product because of its muddy sludge make up definitely will block heater core along with any other components susceptible,i wouldnt recommend l am actually getting steel seal

Didn't work

Used this product on a blown head gasket. Before using the product. I could not drive more than 5 miles without car overheating steam and total loss of coolant. I used the product and all symptoms of the head gasket failure have disappeared. So far in the 3 weeks since I used it No more white smoke No Overheating No Coolant Loss. Genuinely Surprised and Amazed.

Works great used it before and had no problems

Didn't work for me.

Muy bien perfecto estado

Je suis médusé. J ai procédé strictement aux consignes d utilisation. J ai en suite parcouru 50 km pour évaluer. Rien ne s allume au tableau de bord. Puis j ai roulé en tout 1500 km dont 1100 d une traite avec de courtes pauses. Et pas une goûte d eau de rajouté.. Je suis super content. Au top ce produit.

Lo trovato poco utile nella mia cyclette.

Usato su Nissan Serena 2000 benzina 16 valvole. Beveva 1 litro di acqua ogni 700 km circa, e ogni tanto andava a tre cilindri perchè si bagnava una candela. Dopo un solo trattamento, eseguito secondo istruzioni del commerciante, il risultato è stato immediato e duraturo. Acqua sempre a livello massimo, motore che gira bene. Contentissimo di aver risparmiato almeno 1800 € per la riparazione della guarnizione della testa. Ottimo, risolutivo acquisto.

attention ,produit a ne pas achete et surtout pas utilisé.suite à une fuite eau externe joint de culasse ,j'ai utilisé ce produit soit disant miracle et garantie 100%.Après 2 semaines ,la fuite étant toujours presante,j'ai fait change le joint de culasse par un garage qui a constater que tout le circuit d'eau était bouche par des bloc de couleur rose qui est bien entendu la couleur du produit que j'avais mis dans le circuit. photo a l'appui.le mécano m'a informé que j'avais eu de la chance de ne pas casse mon moteur .j'ai du payer un nettoyage du circuit en plus du joint de culasse 2000€ de réparation aulieu de 1600€ prévu.
