PCF101590C is a plastic replacement unit, compatible with both the original metal and plastic tank designs. A cracked or leaking expansion tank causes coolant loss, overheating, and potential head gasket failure - particularly relevant on the 200Tdi, 300Tdi, and V8 engines fitted to these vehicles.\u003c\/p\u003e\n\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003ePlastic construction - replaces both original metal and plastic expansion tank variants\u003c\/li\u003e\n\u003cli\u003eDirect OEM-specification replacement requiring no modification for installation\u003c\/li\u003e\n\u003cli\u003eFits vehicles up to chassis number GA399973 on Range Rover Classic applications\u003c\/li\u003e\n\u003cli\u003eInspect the pressure cap, associated hoses, and coolant level sensor when fitting - these are common failure points at the same service interval\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch4\u003eVehicle Fitment\u003c\/h4\u003e\n\u003cp\u003eFits Defender (1986–2006), Discovery 1 (1989–1998, excluding V8 Twin Carb), and Range Rover Classic across V8, 2.5L 4-cylinder TD, and VM Diesel variants.\u003c\/p\u003e\n\u003cp\u003eNot sure about fitment?
