It houses the thermostat, which regulates the flow of coolant between the engine and the radiator. When the engine is cold, the thermostat remains closed, allowing the engine to warm up quickly. Once the engine reaches operating temperature, the thermostat opens, allowing coolant to flow through the radiator to maintain optimal engine temperature. A failed thermostat housing can cause coolant leaks, overheating, or poor fuel economy.\u003c\/p\u003e\n\n\u003ch3\u003eKey Features\u003c\/h3\u003e\n\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand New\u003c\/strong\u003e – high-quality materials, rigorously tested\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003e100% OE Performance\u003c\/strong\u003e – direct replacement for OE LR005631 \/ 4646010 \/ 4536880 \/ 1316378\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eComplete Assembly\u003c\/strong\u003e – includes thermostat housing and thermostat\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDurable Construction\u003c\/strong\u003e – built to withstand extreme engine temperatures and coolant exposure\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLeak-Free Design\u003c\/strong\u003e – precision-machined sealing surfaces ensure a secure, long-lasting seal\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePlug \u0026amp; Play\u003c\/strong\u003e – direct fit installation, no modification required\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBritish-Engineered Precision\u003c\/strong\u003e – Designed by GB\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003e12-Month Warranty\u003c\/strong\u003e – peace of mind\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFitment\u003c\/h3\u003e\n\n\u003ctable style=\"width:100%; border-collapse: collapse;\"\u003e\n  \u003cthead\u003e\n    \u003ctr style=\"background-color:#f5f5f5;\"\u003e\n      \u003cth style=\"border:1px solid #ddd; padding:8px; text-align:left;\"\u003eVehicle\u003c\/th\u003e\n      \u003cth style=\"border:1px solid #ddd; padding:8px; text-align:left;\"\u003eChassis\u003c\/th\u003e\n      \u003cth style=\"border:1px solid #ddd; padding:8px; text-align:left;\"\u003eYears\u003c\/th\u003e\n      \u003cth style=\"border:1px solid #ddd; padding:8px; text-align:left;\"\u003eEngine\u003c\/th\u003e\n    \u003c\/tr\u003e\n  \u003c\/thead\u003e\n  \u003ctbody\u003e\n    \u003ctr\u003e\n\u003ctd style=\"border:1px solid #ddd; padding:8px;\"\u003eLand Rover LR3 \/ Discovery 3\u003c\/td\u003e\n\u003ctd style=\"border:1px solid #ddd; padding:8px;\"\u003eL319\u003c\/td\u003e\n\u003ctd style=\"border:1px solid #ddd; padding:8px;\"\u003e2005–2009\u003c\/td\u003e\n\u003ctd style=\"border:1px solid #ddd; padding:8px;\"\u003e4.4L V8 Petrol (AJ-V8)\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd style=\"border:1px solid #ddd; padding:8px;\"\u003eLand Rover Range Rover Sport\u003c\/td\u003e\n\u003ctd style=\"border:1px solid #ddd; padding:8px;\"\u003eL320\u003c\/td\u003e\n\u003ctd style=\"border:1px solid #ddd; padding:8px;\"\u003e2006–2009\u003c\/td\u003e\n\u003ctd style=\"border:1px solid #ddd; padding:8px;\"\u003e4.4L V8 Petrol (AJ-V8)\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd style=\"border:1px solid #ddd; padding:8px;\"\u003eLand Rover Range Rover\u003c\/td\u003e\n\u003ctd style=\"border:1px solid #ddd; padding:8px;\"\u003eL322\u003c\/td\u003e\n\u003ctd style=\"border:1px solid #ddd; padding:8px;\"\u003e2006–2009\u003c\/td\u003e\n\u003ctd style=\"border:1px solid #ddd; padding:8px;\"\u003e4.4L V8 Petrol (AJ-V8)\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003c\/tbody\u003e\n\u003c\/table\u003e\n\n\u003cp\u003e\u003cstrong\u003eNote:\u003c\/strong\u003e For 4.4L V8 petrol engines only.
