Bar's Leaks 1100 Block Seal Head Gasket Sealant - 20 oz.How does the need for a block & cracked head sealant come up in the first place? Usually by overheating, which can be caused by a damaged head gasket, cracked head or a leaking block. Bar’s Leaks Head Gasket Repair eliminates this problem — guaranteed. This product contains a blend of aramid and refractory fibers, which provide the strength of a bulletproof vest and the heat resistance of fireproof 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
- Stops block leaks
- Seals cracked cylinder heads and blocks
- Repairs blown head gaskets
- Dual Action 2 Part Formula — LIQUID CERAMIC: Liquid penetrates large and small leaks to form a seal actually harder than the original head gasket — REINFORCED FIBERS: Fiber additives lock together with liquid to increase strength and promote a permanent seal
- Head Gasket Sealant is NOT COMPATIBLE with antifreeze and must only be added to the cooling system after ALL ANTIFREEZE has been flushed and removed.
