On the 4.0 and 4.6 litre V8 engines fitted to the Discovery, a deteriorated or cracked bleed hose can introduce air pockets into the system, leading to localised overheating, inconsistent temperature gauge readings, and heater performance loss. Replacing a failed hose restores the integrity of the cooling circuit's bleed path.\u003c\/p\u003e\n\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003eMoulded rubber construction designed to withstand sustained underbonnet temperatures and coolant exposure\u003c\/li\u003e\n\u003cli\u003eReplicates the original routed profile for straightforward fitment without modification\u003c\/li\u003e\n\u003cli\u003eSupplied as a direct OEM-specification replacement for part number PCH000420R\u003c\/li\u003e\n\u003cli\u003eInspect hose clips and the expansion tank bleed port for corrosion or wear when replacing this hose\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch4\u003eVehicle Fitment\u003c\/h4\u003e\n\u003cp\u003eThis hose fits Land Rover Discovery models equipped with the V8 petrol engine, covering both 4.0 and 4.6 litre variants across the Discovery II generation.\u003c\/p\u003e\n\u003cp\u003eNot sure about fitment?
