BlueDevil Head Gasket Sealer offers a technical, non-particulate solution that bonds to metal, aluminum, cast, alloy and plastic surfaces so you can address many common coolant leaks quickly. The product is compatible with both gasoline and diesel engines and is formulated not to clog cooling passages or harm engine components.\u003c\/p\u003e\n\n\u003ch3\u003eHow does this sealer work to stop a head gasket leak?\u003c\/h3\u003e\n\u003cp\u003eThe formula flows into the cooling system, reaches the leak site, and chemically bonds to the metal edges around the breach, forming a flexible, heat-resistant seal.
