Repairs Blown Head & Intake Gasket Leaks
Bar's Leaks® Professional Carbon Fiber Block Seal Head Gasket & Cooling Sealant is the strongest antifreeze compatible repair on the market. A key benefit of this product is the material stays in the cooling system to seal up any future minor cooling system leaks the vehicle might have. Your vehicle is a good candidate for this product if it can idle for 15 minutes without overheating or having to add coolant. Sealant penetrates leaking, blown or damaged head gasket area drying to form a seal actually stronger than the original head gasket itself. The best formula to stop all other coolant leaks in plastic, cast iron, copper and aluminum radiators, heater cores, freeze plugs, gaskets, intake manifolds, cylinder heads and engine blocks. Use on hard to stop leaks, even on Northstar engines. The special formulation contains a combination of antifreeze compatible sodium silicate sealing liquid and various size gasket sealing particles reinforced with carbon fiber which penetrate gaps & cracks and harden to permanently stop leaks. It also contains Xtreme Cool™ which stops overheating and reduces water temperature. Use with ALL types of antifreeze including conventional green or blue (Silicate-Based) and extended life red/orange or yellow (OAT/HOAT) coolant. No draining of the cooling system is required. For racing applications works great in straight water.
