Use this 3-Step Head Gasket Repair System to permanently seal cracked cylinder heads, blown head gaskets, intake gasket leaks, block leaks and other severe coolant leaks
Step 1. BAR'S LEAKS® Cooling System Prep & Cleaner. Essential for the proper adhesion of the Head Gasket & Block Sealant. Cleans the entire cooling system including the blown/cracked areas where engine contaminants have entered. Containing particles suspended in a cleaning liquid, formulation not only penetrates and cleans cracks and holes, it scrubs the surface to a like-new condition. Contains no acid, needs no neutralizing. Safe for all cooling systems including copper and aluminum.
Step 2. BAR'S LEAKS® Head Gasket & Block Sealant. Stops small and large leaks. Penetrates cracks and damaged or blown head gasket areas. Dries to form a seal stronger than the original head gasket itself. Stops all block leaks. Ultra-strong fibers (carbon fiber, aramid, refractory) work like rebar in concrete to form a permanent seal that's stronger than steel and super-high heat resistant (it's like a bulletproof vest and fireproof clothing combined!).
Step 3. BAR'S LEAKS® Head Gasket & Block Treatment. Protects, conditions and seals the head gasket and all coolant system parts to prevent future leaks. Formulation contains a coolant wetting agent to reduce water/anti-freeze surface tension, aiding heat transfer and lower operating temperatures. Sodium silicate additive prevents future minor head gasket seepage. Works with all types of anti-freeze.
