Brass bleeder screw, e46 BMW quick fix

The bleeder screw on the expansion tank on the e46 is prone to failure. Replace it with one of these to save yourself a headache later. Cheap and easy. BE CAREFUL OF HOT COOLANT. DO NOT ATTEMPT THIS UNLESS YOU ARE FAMILIAR WITH COOLING SYSTEMS OR SEEK A CERTIFIED MECHANIC. I AM NOT RESPONSIBLE FOR ANY PERSONAL INJURY THAT MAY RESULT.
