What is engine sealant? If your vehicle has a cracked radiator, leaking coolant hoses, malfunctioning thermostat or blown head gasket your vehicle has a very high chance of overheating. If the head gasket is blown you may be facing an expensive repair bill, especially if the head is warped or cracked. However there is an option that is easy on your wallet and easy to use. Liquid engine sealant is a chemical combination that can be added to an engine to seal leaks. Blown head gaskets, warped heads and cracked engine blocks and heads are all problems that can generally be treated by engine sealant.

engine sealant is a liquid made up of chemicals such as sodium silicate. As the liquid dries it solidifies into a hard compound strong enough to withstand the temperature, chemicals and pressure found inside an engine.

After engine sealant is added to the engine and then the engine started, the engine sealant moves through the engine. When the engine sealant comes in contact with a temperature difference, usually found around leaks or damage, a thermo-chemical bonding process begins. The resulting solidification causes the troubled area to be sealed and stop leaking.

Fibrous material or particles are commonly found in some engine sealants, these are added to assist in the patching process. The fibrous materials or particles do aid in the sealing process, however they also pose the possibility of clogging the coolant channels throughout the engine, radiator and thermostat. Before choosing an engine sealant, research what type will be the best for your application. Also be sure to follow the correct instructions from the manufacturer, to prevent further harm to the engine and ensure the best performance from the engine sealant you use.

When to use engine sealant: engine sealant is most commonly used to repair a blown head gasket. How do you know if you’ve got a blown head gasket? There are a number of symptoms that can indicate your engine has a blown head gasket. Overheating is one of the main and most destructive symptoms associated with a blown head gasket and can be caused by a variety of issues relating to the head gasket.

If the head gasket is allowing oil to flow into the coolant channels the oil will prevent the coolant from doing its job as well as rob the engine of the oil it needs to lubricate its moving parts. The two factors ineffective cooling due to the oil and coolant mixing combined with the increased friction from the poorly lubricated parts can cause a vehicle to quickly overheat. If the gasket is allowing coolant to escape into the cylinders major engine damage can result, the main symptoms of this occurring is steam issuing from the tail pipe and large loss of coolant. This again will cause the engine to quickly overheat. While all of these problems can cause large amounts of damage to a vehicle, they can be repaired through the use of engine sealant. However action needs to be taken quickly, once the problem has been identified early for an adequate repair to take place.
