This version includes an integrated coolant level sensor, which triggers a dashboard warning when fluid drops below the minimum threshold - a common failure point on Discovery 3 and 4 models that can mask slow coolant loss from leaking hoses or the EGR cooler. Replacing a cracked or sensor-faulty tank restores accurate level monitoring and prevents air ingestion into the cooling system.\u003c\/p\u003e\n\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003eSupplied with integrated coolant level sensor connector, matching the original sensor-equipped specification\u003c\/li\u003e\n\u003cli\u003eDirect OEM-equivalent fitment - no modification required for installation\u003c\/li\u003e\n\u003cli\u003eGenuine Land Rover part number LR020367, ensuring correct cap thread, pressure rating, and hose port configuration\u003c\/li\u003e\n\u003cli\u003eInspect the filler cap, top hose, and sensor wiring connector during replacement as these commonly deteriorate simultaneously\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch4\u003eVehicle Fitment\u003c\/h4\u003e\n\u003cp\u003eFits Discovery 3 (2005–2009) with 2.7L diesel, 4.0L and 4.4L V8 petrol engines, Discovery 4 (2010–2016) with 2.7L and 3.0L diesel and 4.0L, 3.0L SC and 5.0L petrol engines, and Range Rover Sport (2010–2013) with 3.0L diesel, 3.6L V8 diesel, and 5.0L SC petrol engines.\u003c\/p\u003e\n\u003cp\u003eNot sure about fitment?
