What is engine block sealer?
When an engine overheats it can be for one or more of a variety of reasons, the radiator could be cracked, the thermostat may be malfunctioning, the coolant hoses could be leaking and the cylinder head gasket may be blown. In the event of a blown head gasket you could be looking at an expensive repair bill particularly if the head has warped or cracked. An option available however is the use of a liquid engine block sealer. engine block sealer is a chemical compound that is added to the engine to seal any leaks that may have occurred. Problems that are usually able to be treated by engine block sealer are blown head gaskets, warped heads and cracked engine blocks and heads. The chemicals in engine block sealers such as sodium silicate are liquid chemicals that as they dry solidify into a substance that can withstand the pressure, heat and chemicals that occur in combustion engines. When the engine block sealer is added to an engine and the engine is then started, the engine block sealant is distributed throughout the engine. At the site of any damage there is usually a temperature difference, it is this difference in temperature that causes the engine block sealer to solidify and seal the troubled area with the thermo-chemical bonding process. Some engine sealers also use particles or fibrous materials to aid in the patching process. While these do aid in the forming of a seal these particles can clog or block channels throughout the engine and may do more harm than good. Be sure to research the engine block sealer you intend to use and ensure that you follow the provided instructions carefully to be certain you get the most from the product. When to use engine block sealer:
The most common situation that engine block sealer is used is when an engine has a blown head gasket. There are many symptoms that your car may show that are indicative of a blown head gasket and that can be stopped by using an engine block sealer. One of the symptoms quickly noticed by the driver is a lack of power due to the loss of compression. Overheating is another symptom of a blown head gasket that can be treated using engine block sealer. Over heating caused by a blown head gasket occurs because exhaust gasses or oil is leaking into the coolant channels. Also if oil is leaking into the coolant channels or coolant is leaking into the oil channels this can cause excessive wear and tear on the internal engine parts. If the vehicle has steam issuing from the exhaust, it is most likely caused by coolant leaking into the cylinders. This can cause extensive damage to the engine and is usually first noticed by large coolant loss causing the engine temperature to rise above its optimal running temperature. All of these symptoms can be quickly and relatively inexpensively repaired through the correct use of engine block sealer.
