2 pack) Bar's Leaks Block Seal Head Gasket Fix Automotive Additive 24 oz

Bar’s Leaks®Block Seal Head Gasket Fix is the easiest solution to stop head gasket coolant leaks. No draining of the cooling system is required. One step formulation contains a combination of antifreeze compatible sodium silicate sealing liquid and various size gasket sealing particles which penetrate gaps and cracks then harden to permanently stop leaks. This works because of the extreme heat inside the combustion chamber (5000°F) that acts as a catalyst to permanently harden the material to make it stronger than the actual head gasket itself. Your vehicle is a good candidate for this product if it can idle for 20 minutes without overheating or having to add coolant. Use on ALL water cooled gasoline and diesel engines. Heavy duty formula works on aluminum and cast iron heads & blocks, along with sealing all other engine cooling system leaks better than a traditional stop leak. This includes repairing head gaskets, cylinder heads, intake gaskets, cracked blocks and freeze plugs. Use with ALL types of traditional or extended life coolant including yellow, orange, pink, red, blue, purple and green silicate based & non-silicate based (OAT/HOAT) 50-50 mix antifreeze, and/or water. Bar's Leaks 1111 Block Seal Head Gasket Fix Automotive Additive, 24 oz Safely Seals Gasket And Other Severe Leaks Quickly and Permanently Stops Coolant Leaks One Step—No Draining Required—Easy To Use Use with ALL types of traditional or extended life coolant
