Hyundai head gaskets are most like likely to fail during an episode of engine overheating, so take the time to do all the recommended engine maintenance measures. When adding coolant, use the right type and mixture of coolant. Replace the fuel and air filters regularly. And if you feel constant misfires in your engine, get a tune-up right away. Those misfires might be detonations and preignition episodes, which can jar your Hyundai head gasket. You can avoid a blown head gasket with these sensible, inexpensive measures. After all, a blown head gasket can cause the destruction of an engine if the coolant leaks into the engine. That occurs when the metal in the cylinder head warps (usually under tremendous heat pressure) and the gasket 'blows,' releasing coolant and oil. Your Hyundai head gasket can be found on top of the engine, where it seals the head (the top of the engine) to the rest of the body of the engine. When the coolant is released, you might notice white smoke coming out of your tailpipe. That is the steam from the coolant as it evaporates in the heat of the engine. Or, you will see oil in your coolant and coolant in your oil. At that point, you must decide whether to do the head gasket job yourself, or go to a mechanic. If you do it yourself, you can save significantly on repair bills. Start first with ordering your Hyundai head gasket here, and be assured of its quality.
