ITEM #: 4443443 Bar's Leaks® Head Gasket Repair is designed to permanently fix coolant leaks and keep your vehicle on the road. Effective on cast iron or aluminum blocks and heads, the repair fluid can help solve overheating caused by a blown head gasket, cracked head, or leaking block. Its proprietary formula blends liquid ceramic and aramid fiber to penetrate large and small leaks and form a strong, reinforced seal that's harder than the original head gasket. This listing is for each.
