The Award Winning Steel Seal

Had head gasket replaced, which cured coolant leak into oil for about 1 month only, and cost £860. Flushed system and added Steel Seal 9 weeks ago, and all is still good at present. Wish I had just done this the first time, and saved myself the £860.

Most important you will get a horrible gel if you don’t drain and flush with fresh water. Worked well for a season, stopped pressurisation. Signs now that it may be wearing off. Still, I’m prepared for an annual bottle as sooo much cheaper than a head gasket job on a banger

This stuff does work, how long for I don't know time will tell. Bought for my partners car as she was losing water somewhere, I put this in following the ideal procedure water out, engine flush, and adding back into the system, allowing to circulate round the engine. She's not lost any coolant upto now and its been over a week. Was very sceptical being a 40 quid bottle over what could be an expensive repair job but upto now it seems to have done what it needs to.

100% saved the day thanks

Didn't work followed the instructions correctly didn't work

It didn't work on my car for the job needed.

This stuff worked for about 6-7 months when I contacted the seller (steal seal) they where more than happy to stick to there policy of lifetime guarantee and after I sent in proof of purchase and a claims form they sent out a new bottle. I will recommend this product to anyone in a sticky situation and needs a quick fix for there head gasket. My

I wasn't sure if this would work as I was losing about 170ml of coolant a day and had water in the oil. I used this product as directed, took it for a few miles drive, let the engine cool and topped up with water to the fill line. I checked the coolant level after a few days and it was ever so slightly below the fill line. I can still smell exhaust fumes inside the cabin when idling which suggests that exhaust gases are seeping into the heater matrix so it hasn't fixed it fully but I think it may have bought me a little time. I'm scrapping the car soon anyway I just need it to survive another few months until I can afford another car.

Hallo , also ich hab ohne zu übertreibennoch nie zuvor was vergleichbar effektives gesehen. Wir waren (ein paar Tage bevor ich Steel seal gekauft habe )in einer Auto Werkstatt mit unserem Opel Astra turbo j 1.4 ,wegen ständigem Kühlmittel Verlust und auch wegen klingelnder Motor Geräusche. Die Aussage der Werkstatt Zylinderkopf Dichtung defekt und weitere Dichtungen im Motor inneren. Einzigste Möglichkeit alles auseinander nehmen und Alle Dichtungen tauschen . Alles für nur 800€ kotz nur 800 € Hahaha. Und dann hab ich auf eigene Faust recherchiert und bin auf dieses Produkt gestossen . Der Preis von knapp 80€ war mir am Anfang nicht so geheuer ....Aber mir war letztendlich egal ob jetzt 800€ oder eben 80 € mehr ( falls das Produkt auch für'n A..... War). Aber nein ,alles wie auf der Flasche beschrieben durchgeführt und schon während der ersten halbe Stunde im Reperatur (Standgas Modus );) konnte Mann deutliche Veränderungen der Motor Geräusche hören . Der Motor wurde simpel gesagt wieder um einiges leiser und lief auch wieder viel ruhiger und runder .Und die Kühlflussigkeit bleibt auch wieder da wo sie hingehört;) Also Daumen Hoch Top Produkt .

perfect , fixed small leak in head gasket

It didn't work as expected. just wondering how to apply for refund

Non ha funzionato su una Punto 188 1.2 8v del 2000: la temperatura dell'acqua sale ed entrano gas combusti nel circuito del refrigerante, perche' la guarnizione di testa e' rotta. Pur avendo drenato il vecchio refrigerante e usato solo acqua e SteelSeal e pur togliendo il termostato per far circolare subito il liquido, non ho ottenuto la sigillatura. Peccato perche' chiedono 450 euro per firare la guarnizione di testa.
