{"product_id":"cap-pressure-radiator","title":"Cap - Pressure - Radiator for Defender (1986 – 2006) Expansion Tank - TD5 – PCD100160","description":"\u003cp\u003eThe radiator pressure cap for the expansion tank maintains the correct system pressure within the cooling circuit, raising the boiling point of coolant and preventing cavitation or boil-over. On TD5-engined Defenders, a faulty or worn pressure cap is a common cause of coolant loss, overheating, and collapsed hoses, as the valve fails to hold or release pressure at the correct threshold. Using the correct rated replacement cap is essential to avoid repeat failures or damage to hoses and the expansion tank itself.\u003c\/p\u003e\n\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003ePressure-rated cap designed to maintain specified system pressure on the expansion tank\u003c\/li\u003e\n\u003cli\u003eDirect replacement - fits the expansion tank neck without modification\u003c\/li\u003e\n\u003cli\u003eMeets OEM specification for TD5 and compatible Defender cooling systems; part number PCD100160\u003c\/li\u003e\n\u003cli\u003eInspect the expansion tank filler neck for cracks or warping when fitting; replace coolant if contaminated\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch4\u003eVehicle Fitment\u003c\/h4\u003e\n\u003cp\u003eFits Defender 1986–2006 (TD5 expansion tank), Defender 2007 onwards up to VIN 7A000001, Defender 2007 onwards Td4 2.4 Diesel (pressure expansion tank), and Freelander 1 up to VIN 3A289375.\u003c\/p\u003e\n\u003cp\u003eNot sure about fitment?
