White smoke from the exhaust is produced when cooling water enters the combustion chamber via a defective cylinder head gasket. The cooling water is burnt and white exhaust smoke is produced. There is a risk of water hammer and total engine failure. Steel Seal® repairs the leak and closes it permanently. Without removing and replacing the head gasket.
Oil in the cooling water impairs the cooling performance and cooling water in the oil reduces the lubricity of the engine oil. This oil-water emulsion leads to extremely high wear within a very short time and threatens irreparable damage to the engine. As long as the engine is still starting and running, Steel Seal® repairs the damage cost-effectively and permanently.
Coolant loss with a defective cylinder head gasket almost always begins gradually and without any leakage. The loss of water remains undetected until the coolant indicator lights up. Coolant has to be topped up again and again after a journey. The earlier the problem is tackled with Steel Seal®, the greater the chances of a successful and lasting repair and the greater the certainty of saving high workshop costs.
A blown head gasket or a crack in the cylinder head is usually the result of an engine that is overheating. The cause of the overheating must be identified and rectified. The leaking cylinder head gasket can be sealed cost-effectively and permanently with Steel Seal®.
