{"product_id":"cap-expansion-tank-radiator-192390","title":"Cap - Expansion Tank - Radiator for Discovery 3 (2005 – 2009) 4.4L V8 Petrol – PCD500030","description":"\u003cp\u003eThe PCD500030 is the pressure cap for the coolant expansion tank, responsible for maintaining the correct pressure within the cooling system and allowing coolant to flow between the expansion tank and the radiator circuit. A faulty or worn cap can cause the system to lose pressure, leading to coolant loss, overheating, and potential cylinder head damage - particularly relevant on the high-output 4.4L V8 and supercharged petrol engines. Replacing a degraded cap is a low-cost preventative measure against more serious cooling system failures.\u003c\/p\u003e\n\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003eDesigned to maintain the correct system pressure rating for Land Rover cooling systems\u003c\/li\u003e\n\u003cli\u003eDirect replacement for the original expansion tank cap - no modification required for fitting\u003c\/li\u003e\n\u003cli\u003eGenuine Land Rover part number PCD500030, meeting OEM specification\u003c\/li\u003e\n\u003cli\u003eOne cap required per vehicle; inspect the expansion tank itself for cracks or discolouration when replacing\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch4\u003eVehicle Fitment\u003c\/h4\u003e\n\u003cp\u003eFits Discovery 3 (2005–2009) 4.4L V8 and 4.0L V6 Petrol and 2.7 V6 Diesel, Freelander 1 (to 3A289376), Range Rover (2002–2009) including 3.6 V8 Diesel, and Range Rover Sport (2005–2009) with 2.7 V6, 3.6 V8 Diesel, 4.2 Supercharged, and 4.4 V8 Petrol engines.\u003c\/p\u003e\n\u003cp\u003eNot sure about fitment?
