The Award Winning Steel Seal

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.

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

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.

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.

Hab es beim Audi Cabriolet 2,6 von 1994 angewendet, da die rechte Kopfdichtung einen Schaden hatte (Kühlmittel gelang in den Brennraum von Zylinder 3). Es hat einwandfrei funktioniert. Hab 4 Monate danach erst die Kopfdichtungen erneuert. Bis dahin lief der Motor wunderbar ohne weiteren Kühlmittelverbrauch.

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.
