Bar’s Leaks 1100 Block Seal Head Gasket Repair, 20 Oz

Bar’s Leaks Block Seal Head Gasket Repair is scientifically formulated to permanently seal coolant leaks that are the cause of most overheating problems.

For most vehicles, this is the last chance before going to a junk yard or paying an expensive repair bill. This repair contains a blend of aramid and refractory fibers giving the strength of a bullet-proof vest and the heat resistance of fire-proof clothing. As these particles penetrate a crack or the blown head gasket area, they lock together and bond forming a hard permanent ceramic type seal. Your vehicle is a good candidate for this product if it can idle for 20 minutes without overheating or having to add coolant. Works effectively on cast iron or aluminum blocks & heads.

Detailed English/Spanish instructions on back booklet label take you through each step of using the product. Overheating can be caused by a blown head gasket, cracked head or leaking block. Bar’s Leaks Block Seal Head Gasket Repair eliminates this problem. In addition, overheating can be caused by a stuck thermostat, bad water pump or defective radiator cap. Make sure these cooling system parts are in good working order before using Bar’s Leaks Block Seal Head Gasket Repair. When one of these parts fails, it can cause the head gasket to fail.
