The OEMTOOLS 37145 Combustion Leak Detector offers a quick and efficient way to test for combustion leaks that result from head gasket, cylinder head and engine block leaks. This easy-to-use tool pulls air from the cooling system up through the leak tester fluid (OEMTOOLS 25739, sold separately). If carbon dioxide is present, the leak tester fluid color will change to yellow — signifying a combustion leak. This tool includes a blow molded case for convenient storage.Warning: This product can expose you to chemicals which are known to the State of California to cause cancer or reproductive defects.
