There is nothing worse than being out on the highway driving at 65 or 70 mph when the temperature gauge pegs or the light comes on and you notice a plume of white smoke pouring out of your tailpipe. It can be very scary especially if you have no mechanical knowledge at all. The first thing you do is pull over to the breakdown lane and call for a tow truck. When the truck arrives the operator looks at your car and tells you he thinks you have a blown head gasket. When you get to the repair shop the mechanic offers you two choices an expensive rebuild or you can try a head gasket sealer just to see if it works. Chances are you could most likely have avoided this situation if you paid just a little more attention to your car. Generally your car will exhibit symptoms that will let you know that the head gasket is leaking and in need of some attention. It might be that you have to add coolant to the reservoir, something you should almost never have to do.
Of course you could just put this off as the weather being hotter than usual, just like the fact that the temperature gauge has been running a little higher. If you had seen these signs you might have been able to use a head gasket sealer to avoid the breakdown but you missed the signs. We have all seen the commercials on television that tell us that this head gasket sealer or that one will keep your engine from having to be torn apart and be repaired, the question is do any of them really work or are they all just a hit and miss product. Many of them rely on fibers and metal particles that are supposed to slow fill in the break in the gasket and seal off the leak. Some of them work relatively well as long as you catch the leak when it is relatively small, but do little to help your engine when you have waited too long and the gasket is completely blown.
This has been the case for many years and has given the head gasket sealer a bad name with both the public and the automotive repair industry. For the auto mechanics point of view, they have had to deal with unhappy customers who tell them first that their bills are too high and that the chemicals will save them money. Then when the chemicals did not work they would come back and still complain about the bills and how the chemical did not work and the mechanic should have been more convincing, it was a no win situation. Today there is a head gasket sealer that has been proven to work by hundreds of automotive repair shops across the country. Mechanics and customers alike are happy to recommend Steel Seal as the first sealer that will not only fix the small leaks, but will actually completely seal a fully blown head gasket, a warped head or a cracked block without filling your cooling system with a bunch of useless fibers or metal particles.
