Under cyclical thermal stress and elevated system pressures generated by the supercharged \u003cstrong\u003eAJ126\u003c\/strong\u003e and \u003cstrong\u003eAJ133\u003c\/strong\u003e powerplants, these polymer pipes degrade, embrittle, and hairline-crack at the seam lines beneath the supercharger manifold. Concurrently, factory water pump bearings and mechanical seals are known for premature weep-hole leakage, which starves the engine of coolant and leads to localized heat soak, warped cylinder heads, and head gasket failure.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis comprehensive overhaul kit addresses OEM polymer degradation by substituting vulcanized failure points with reinforced cast aluminum crossover pipe construction and an upgraded mechanical water pump. Replacing the thermal-stressed plastic front crossover with corrosion-resistant cast aluminum eliminates split-seam blowouts, while the precision-calibrated thermostat assembly with an integrated sensor ensures accurate coolant flow metering across the radiator core. Complete with upgraded copper-reinforced bleed hardware and synthetic EPDM plumbing, this solution delivers reliable fluid transfer without continuous risk of unmonitored hydraulic pressure drop.\u003c\/p\u003e\n\n\u003ch3\u003eWhat's Included\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e1 Thermostat with Integrated Sensor\u003c\/li\u003e\n  \u003cli\u003e1 Aluminum Coolant Crossover Pipe Assembly\u003c\/li\u003e\n  \u003cli\u003e1 High-Flow Mechanical Water Pump\u003c\/li\u003e\n  \u003cli\u003e1 Thermostat Outlet Hose with Copper Fittings\u003c\/li\u003e\n  \u003cli\u003e1 Copper Bleeder Screw \u0026amp; Crossover Plug\u003c\/li\u003e\n  \u003cli\u003e1 Heater Outlet Hose\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003cdiv style=\"overflow-x: auto; margin-bottom: 20px;\"\u003e\n  \u003ctable width=\"100%\" style=\"border-collapse: collapse; border: 1px solid #e0e0e0; font-size: 14px; min-width: 300px;\"\u003e\n    \u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eFitment\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003e2010-2016 Land Rover LR4\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eEngine \/ Chassis\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003eAJ126 \/ AJ133 \/ L319\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eStock Output\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003e340 hp \/ 332 lb-ft\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eReplaces OEM Part #\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003eAJ812119, AJ813909, C2D20660, LR090630\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003c\/table\u003e\n\u003c\/div\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e2010-2016 Land Rover LR4 3.0L Supercharged V6 (AJ126)\u003c\/li\u003e\n  \u003cli\u003e2010-2016 Land Rover LR4 5.0L Supercharged V8 (AJ133)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFrequently Asked Questions \u0026amp; Fitment Warnings\u003c\/h3\u003e\n\u003ch4\u003eDoes this fit the L319 LR4?\u003c\/h4\u003e\n\u003cp\u003eYes, this is a direct fit for the 2010-2016 Land Rover LR4 equipped with the \u003cstrong\u003eAJ126\u003c\/strong\u003e 3.0L supercharged V6 or \u003cstrong\u003eAJ133\u003c\/strong\u003e 5.0L supercharged V8 engines. \u003cstrong\u003eDoes not fit naturally aspirated engines; verify displacement and induction setup before purchase.\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003ch4\u003eDo I need to bleed the cooling system after installing this kit?\u003c\/h4\u003e\n\u003cp\u003eYes, a vacuum-assisted coolant refill and complete manual bleed cycle via the included copper bleeder screw are required to clear air pockets from beneath the supercharger manifold.\u003c\/p\u003e\n\n\u003ch3\u003eThe Land Rover Standard\u003c\/h3\u003e\n\u003cp\u003eEngineered to meet demanding European utility tolerances, this cooling package is designed to ensure factory fitment, reliable sensor communications, and complete operating reliability without triggering Check Engine lights or fault codes.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":67545317540088,"sku":"DS-EPQPAPQJL","price":246.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/performance-water-pump-thermostat-kit-for-land-rover-lr4-2010-2016-3-0l-1.jpg?v=1790721566","url":"https:\/\/performancechiptuning.com\/products\/performance-water-pump-thermostat-kit-for-land-rover-lr4-2010-2016-3-0l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
