Over time, recurring thermal cycling degrades the factory pump's internal printed circuit board (PCB), causing solder joint cracking, motor driver failure, and sudden shutdown without advance mechanical warning. Concurrently, plastic thermostat housings warp and internal wax elements fail, leading to stuck-closed conditions, reduced flow rate, elevated oil temperatures, and forced limp-mode activation under load.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis replacement kit pairs a heavy-duty electric water pump featuring reinforced solid-state electronics with an OE-spec map-controlled thermostat. Built to withstand sustained operating pressures and engine-bay heat soak, the brushless internal motor provides consistent coolant velocity across all engine loads. The integrated thermostat matches factory duty cycles through the engine control module to regulate coolant exchange swiftly. Direct-fit replacement hardware ensures factory torque specifications without housing distortion.\u003c\/p\u003e\n\n\u003ch3\u003eWhat's Included\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e1 Electric Engine Water Pump\u003c\/li\u003e\n  \u003cli\u003e1 Electric Engine Coolant Thermostat\u003c\/li\u003e\n  \u003cli\u003e3 Mounting Bolts\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;\"\u003e2015-2016 BMW X4\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;\"\u003eN55 3.0L Turbo \/ F26\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;\"\u003e300 hp \/ 300 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;\"\u003e11517632426, 11517586928, 11517586929, 11517563659, 11517588885, 11517602123, 11537549476, 11537544788, A2C53326031, A2C59514607, 11206043003\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\u003e2015-2016 BMW X4 3.0L Gas Turbo (xDrive35i \/ M40i)\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 F26 X4?\u003c\/h4\u003e\n\u003cp\u003eYes, this is a direct fit for the 2015-2016 BMW X4 equipped with the \u003cstrong\u003eN55\u003c\/strong\u003e 3.0L turbocharged inline-six engine.\u003c\/p\u003e\n\n\u003ch4\u003eWhy must I check my thermostat before installation?\u003c\/h4\u003e\n\u003cp\u003eTwo distinct thermostat styles exist for these N55 applications; verify physical port alignment with your existing factory unit before final installation.\u003c\/p\u003e\n\n\u003ch3\u003eThe BMW Precision Standard\u003c\/h3\u003e\n\u003cp\u003eEngineered for exacting European tolerances, this assembly maintains factory communication protocols across the vehicle's serial data bus to eliminate diagnostic error codes while preserving precise thermal regulation under aggressive driving conditions.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":67923570884856,"sku":"DS-ED3XTCC4R","price":109.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/performance-water-pump-kit-for-bmw-x4-2015-2016-3-0l-1.jpg?v=1793566708","url":"https:\/\/performancechiptuning.com\/de\/products\/performance-water-pump-kit-for-bmw-x4-2015-2016-3-0l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
