    BMW expansion tank bleed screw fitting

    July 04, 2013

    After struggling with a coolant leak in my 540 I wondered if making a fitting that replaces the bleed screw in the expansion tank found on many BMWs would make the task of pressure testing the cooling system easier. It does! Plus you can test the radiator cap along with the rest of the system. Most cooling system testers require removal of the cap. Look for our part number 1175.
