Tucked beneath the supercharger, these plastic pipes endure intense heat cycles that cause their welded seams to degrade, crack, and fail catastrophically without warning. Furthermore, the factory mechanical water pump seals frequently weep under pressure, while OEM plastic bleeder screws strip out during routine servicing.

The assembly includes a direct-fit replacement water pump engineered for cavitation resistance and continuous flow, paired with an OE-spec thermostat and pre-installed temperature sensor. High-grade copper bleeder hardware and heavy-duty outlet hoses with copper fittings replace factory plastic failure points, restoring high-pressure cooling reliability across the entire operating range.\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 Set\u003c\/li\u003e\n  \u003cli\u003e1 Replacement 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;\"\u003e2010-2018 Land Rover Range Rover Sport\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;\"\u003e\n\u003cstrong\u003eAJ133\u003c\/strong\u003e (5.0L SC), \u003cstrong\u003eAJ126\u003c\/strong\u003e (3.0L SC) \/ \u003cstrong\u003eL320\u003c\/strong\u003e, \u003cstrong\u003eL494\u003c\/strong\u003e\n\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;\"\u003e510 hp \/ 461 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;\"\u003e\n\u003cstrong\u003eAJ812119\u003c\/strong\u003e, \u003cstrong\u003eAJ813909\u003c\/strong\u003e, \u003cstrong\u003eC2D20660\u003c\/strong\u003e, \u003cstrong\u003eLR090630\u003c\/strong\u003e\n\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\u003e2010-2013 Land Rover Range Rover Sport Supercharged (L320 Chassis, 5.0L Supercharged V8)\u003c\/li\u003e\n  \u003cli\u003e2014-2018 Land Rover Range Rover Sport Supercharged \/ HSE Dynamic (L494 Chassis, 5.0L Supercharged V8)\u003c\/li\u003e\n  \u003cli\u003eFits AJ126 3.0L Supercharged V6 and AJ133 5.0L Supercharged V8 applications matching listed OE references\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 L320 and L494 Range Rover Sport?\u003c\/h4\u003e\n\u003cp\u003eYes, this is a direct fit for the 2010-2018 Land Rover Range Rover Sport equipped with the \u003cstrong\u003eAJ133\u003c\/strong\u003e 5.0L supercharged engine and \u003cstrong\u003eAJ126\u003c\/strong\u003e 3.0L supercharged applications. \u003cstrong\u003eDoes not fit naturally aspirated engines.\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 full coolant vacuum fill or thorough mechanical bleed via the included copper bleeder screw is required to prevent trapped air pockets inside the supercharger cooling jackets.\u003c\/p\u003e\n\n\u003ch3\u003eThe Land Rover Precision Standard\u003c\/h3\u003e\n\u003cp\u003eDesigned to maintain strict European operating tolerances, this cooling package eliminates common thermal faults while ensuring precise sensor integration without triggering check engine lights or ECU cooling circuit codes.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":67545314197752,"sku":"DS-E5SFFH9BD","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-range-rover-sport-2010-2018-5-0l-1.jpg?v=1790721516","url":"https:\/\/performancechiptuning.com\/products\/performance-water-pump-thermostat-kit-for-land-rover-range-rover-sport-2010-2018-5-0l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
