Steel Seal is a unique mixture of chemical compounds that have been specially blended to react under sufficient heat and pressure to create a hardened seal in the damaged area of a head gasket or block.

However there are lots of products claiming the same thing.

While there are other products that claim to repair a blown head gasket in a similar way to Steel Seal and these products are predominately comprised of little more than Sodium Silicate and dye.

Unfortunately, while using Sodium Silicate will initially seem to fix the issue, Sodium Silicate is also commonly known as ‘Liquid Glass’ or ‘Water Glass’. The reason for this is that Sodium Silicate once heated and cooled down will harden to a glass like substance. This substance cannot possibly stand up to the heat and pressure within the engine and this ‘seal’ will eventually break and the problem of the blown head gasket will return.

Why Steel Seal?

Many people still believe that a ‘liquid head gasket’ fix cannot work, however Steel Seal has been repairing vehicles for 20 years. When a brand has been going that long, maybe it does work.

      Before I used this my Expedition had large amounts of heavy white smoke coming out of the exhaust and it was also misfiring on cylinder 1. After I used steel seal the white smoke stop and the Expedition is no longer misfiring. I love this product and would highly recommended to anyone who has a coolant into motor issue.

      After two months fighting to start my car (280000 km) in the morning, wearing down the battery until it finally started on 1-2 cylinders, I applied Steel Seal yesterday evening. First thing today was to start the engine and it started immediately on the first try on all 4 cylinders.
      Would highly recommend this product.
