The original with improved formula: effect is now more permanent – repairs all types of cooling water leaks in the engine, such as leaking head gasket, distorted cylinder head or cracked engine block.
Recommended dosage: Engine capacity up to 2.5 litres = 1 bottle. Engine capacity from 2.5 to 4.0 litres = 2 bottles. Cylinder capacity over 4.0 litres = 3 bottles.
Protects the cooling system: unlike other "radiator sealants", Steel Seal is free from fillers (fibres, granules, etc.) and thus prevents unwanted deposits in the cooling circuit. Due to the unique action (thermochemical bonding process), the repair remains permanently after successful application on the cylinder head gasket.
Easy to use without dismantling. No tools required. Detailed step-by-step instructions for correct handling of the product included (English language not guaranteed). You will also receive "Additional instructions for combustion pressure in the cooling system" and other helpful tips for lasting results (English language not guaranteed).
Compatible with all water-cooled engines (cars, trucks, buses, SUVs, tractors, etc.) and commercially available water-based antifreeze (no concentrate, extended or long-life coolants).
