How does engine block sealer work?

Engine block sealers work by sealing the engine head gasket leaks from the inside, using the vehicle’s cooling passages to transport a sealer to the leak. Most sealers work by accumulating at the leak, and forming a seal using the engine’s heat as a catalyst to help cure and harden the seal.
