Product Details

Part # 27145

The OEMTOOLS™ 27145 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 (sold separately: OEMTOOLS™ 25739); 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.
