A faulty or seized bleeder screw can prevent complete air evacuation, leading to localised overheating, inconsistent coolant circulation, and inaccurate temperature readings across the AJ133, AJ200, AJ20D6, AJ20P6, and 3.0L V6 engine families. Correct replacement ensures a reliable seal and repeatable bleed procedure.\u003c\/p\u003e\n\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003eGenuine Land Rover part, manufactured to OEM specification for precise thread fit and sealing performance\u003c\/li\u003e\n\u003cli\u003eDesigned for single-point coolant bleeding - ensure the screw is fully reseated and torqued after each bleed procedure\u003c\/li\u003e\n\u003cli\u003eReplaces the original bleeder screw on engines from chassis prefix EA000001 (Discovery 4) and AA000001 (Range Rover\/Sport)\u003c\/li\u003e\n\u003cli\u003eInspect the sealing washer or O-ring at replacement - a worn seat surface can cause coolant weeping even with a new screw fitted\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch4\u003eVehicle Fitment\u003c\/h4\u003e\n\u003cp\u003eFits Discovery 4 (2010–2016), Range Rover (2010 onwards), Range Rover Sport (2010–2013 and 2014 onwards), Discovery 5 (2017 onwards), and Defender (2020 onwards) across petrol and diesel engine variants including 2.0L, 3.0L, 4.4L, and 5.0L units.\u003c\/p\u003e\n\u003cp\u003eNot sure about fitment?
