Featuring high-durability internal bearings, a reinforced impeller design to eliminate cavitation at high RPM, and a rigid, heat-stabilized housing with direct-fit sensor ports, it sustains uniform coolant velocity across the engine block. Designed to match OE hydraulic flow dynamics without modifications, this drop-in assembly eliminates coolant cross-leakage, prevents thermal expansion fractures, and ensures long-term cooling system integrity under heavy engine loads.\u003c\/p\u003e\n\n\u003ch3\u003eWhat's Included\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e1 Mechanical Water Pump Assembly\u003c\/li\u003e\n  \u003cli\u003e1 Thermostat Housing Assembly with Integrated Thermostat and Sensor Connector\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;\"\u003e2004-2006 BMW X3\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;\"\u003eM54 (2.5L \/ 3.0L) \/ E83\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;\"\u003e184 hp \/ 175 lb-ft (2.5L) | 225 hp \/ 214 lb-ft (3.0L)\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;\"\u003e1152090, AW9261, 41057, 1430825, 11M41017KF\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\u003e2004-2006 BMW X3 2.5L Gas Naturally Aspirated\u003c\/li\u003e\n  \u003cli\u003e2004-2006 BMW X3 3.0L Gas Naturally Aspirated\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 E83 X3?\u003c\/h4\u003e\n\u003cp\u003eYes, this is a direct fit for the 2004-2006 BMW X3 equipped with the \u003cstrong\u003eM54\u003c\/strong\u003e 2.5L and 3.0L naturally aspirated inline-six engines.\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 complete coolant flush and systematic air-bleed procedure via the expansion tank bleeder screw is mandatory to eliminate air pockets and guarantee accurate thermostat operation.\u003c\/p\u003e\n\n\u003ch3\u003eThe BMW Precision Standard\u003c\/h3\u003e\n\u003cp\u003eManufactured to strict European engineering tolerances, this direct OE replacement kit eliminates common Check Engine Lights related to cooling circuit thermal runouts while maintaining the exact operational temperature window specified for BMW M54 engine electronics.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":67923275579640,"sku":"DS-E3SPZD2IJ","price":81.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/performance-water-pump-kit-for-bmw-x3-2004-2006-2-5l-3-0l-1.jpg?v=1793557558","url":"https:\/\/performancechiptuning.com\/es\/products\/performance-water-pump-kit-for-bmw-x3-2004-2006-2-5l-3-0l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
