The 1175 is a fitting that replaces the stock bleeder screw in many BMW expansion tanks. Using the 1175 and a Power Bleeder or another source of pressure allows you to test all the components of your cooling system for leaks. Very simple to use - just remove the bleed screw and replace with the 1175. Follow service manual directions for pressure test time and pressurization. When done testing remember to depressurize the system by first clamping off the 1175 and then SLOWLY removing the radiator cap. Note the 1175 is the brass fitting, hose and coupler, Power Bleeder sold separately. BMW Applications:
