Hallo, mein Passat hat knapp 600.000 km auf der Uhr, und seit etwa 30.000 km pumpt sich das Kühlsystem zunehmend auf. Der Kühlwasserstand fiel unter Minimum, die Kontrollanzeige leuchtete, und schließlich lag der Verbrauch bei 1 Liter Kühlwasser pro 10 km. Eine Zylinderkopfüberholung war unwirtschaftlich, also suchte ich online nach Lösungen und stieß auf Steel […]

Hallo liebes Steel Seal Team,warum habe ich erst jetzt von euch erfahren? Mein Toyota hatte einen Kopfdichtungsschaden, und bei der Recherche stieß ich auf euch. Nach den vielen positiven Bewertungen habe ich Steel Seal bestellt und die Anwendung gemäß Anleitung durchgeführt. Schon währenddessen verschwand der weiße Qualm fast vollständig, und meine Hoffnung wuchs. Nach Abschluss

Liebes Steel Seal Team, ich möchte Ihnen auf diesem Weg zu einem hervorragenden Produkt gratulieren und meine positiven Erfahrungen mitteilen. Bei unserem älteren Peugeot 206, Bj. 2005, ca. 210.000 km, zeigten sich vor ein paar Tagen, mitten im Urlaub, die typischen Symptome einer durchgebrannten Zylinderkopfdichtung: Startschwierigkeiten, unrunder Motorlauf zuerst auf nur 3 Zylindern, Kühlmittelverlust und weißer Qualm

I had to use the cylinder head sealing set from Steel Seal twice, but now the cooling system in my Opel has been absolutely leak-proof for 6 months. I am very satisfied and hope it stays that way for longer. Josef Held18.05.2024, 92676 Eschenbach

After the simple and well-described application, all problems have been solved. The car runs smoothly and performance has improved. The CO2 test is now negative. Super result! Roland Lubitz01.05.2024, 24787 Fockbek

Hello, here is some absolutely enthusiastic and long overdue feedback:On July 13, 2021, I ordered two Steel Seal cylinder head gasket fixes from you (invoice no. 20211149). It was a purchase out of necessity, as our motorhome (Renault Master 2 base, dCi 140) increasingly - but not always - showed white smoke in the first few minutes after a cold start.

We were about to sell our Audi A4 because of coolant loss when I came across Steel Seel's ad! My trusted mechanic had heard of it before! Followed the instructions exactly! Unfortunately, he first had to drain the pink coolant and flush the cooling system. But I have to say, it worked! So far it's not losing any

I had compression pressure in the cooling circuit of my Cadillac. First I located the defective cylinder and switched it off (spark plug out and injection disconnected). I then used Steel Seal as prescribed. When I drove the car the next day, all the previous problems had disappeared as if by magic. By using

So, from one day to the next, Audi loves to burn water instead of diesel. Massive water loss and uneven engine running as well as high pressure in the cooling system. At 250,000 kilometers, the repair no longer makes sense. I did a bit of research and came across Steel Seal. Read a lot of positive opinions and also a few where it didn't work. With

Problem: Engine light on, temperature in the red range and water vapor from the exhaust After using Steel Seal: Engine light off, temperature remains constant at 90° degrees and no more water vapor from the exhaust. As if nothing had ever happened... I will recommend it to others! Hans-Joachim Schubert15.06.2023, 84048 Mainburg
