Under continuous thermal cycling and vibration inside the cramped turbocharged engine bay, the OEM composite plastic impellers bind, crack, or shear off the shaft. Simultaneously, high heat degrades the internal solder joints of the factory electronics, triggering sudden communication loss over the BSD (Bit Serial Device) bus. Paired with a wax-element map-controlled thermostat prone to sticking, this failure mode causes sudden loss of coolant circulation, limp mode activation, and rapid head gasket or cylinder head warping on the \u003cstrong\u003eN54\u003c\/strong\u003e twin-turbo and \u003cstrong\u003eN55\u003c\/strong\u003e twin-scroll powerplants.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis replacement cooling kit pairs a reinforced, brushless electric water pump with an OE-calibrated, map-controlled thermostat designed to withstand severe duty cycles. Featuring an upgraded internal motor drive, robust electrical sealing, and a thermal-resistant composite impeller, the pump delivers consistent volumetric flow across the entire RPM range regardless of engine speed. The electronically managed thermostat features rapid-response heating elements to modulate block temperatures instantly between economic cruise and high-load boost cycles. Supplied with single-use aluminum mounting hardware to ensure correct torque specs and prevent galvanic corrosion against the magnesium-aluminum engine block.\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;\"\u003e2009-2016 BMW Z4\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\u003eN54B30 \/ N55B30\u003c\/strong\u003e \/ \u003cstrong\u003eE89\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;\"\u003e300-335 hp \/ 300-332 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;\"\u003e\u003cstrong\u003e11517632426, 11517586928, 11517586929, 11517563659, 11517588885, 11517602123, 11537549476, 11537544788, A2C53326031, A2C59514607, 11206043003\u003c\/strong\u003e\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\u003e2009-2016 BMW Z4 sDrive35i (3.0L Turbo Inline-6 Gas)\u003c\/li\u003e\n  \u003cli\u003e2011-2016 BMW Z4 sDrive35is (3.0L Turbo Inline-6 Gas)\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 E89 Z4?\u003c\/h4\u003e\n\u003cp\u003eYes, this is a direct fit for the 2009-2016 BMW Z4 equipped with the \u003cstrong\u003e3.0L Gas Turbo\u003c\/strong\u003e engine. \u003cstrong\u003eNote: Two thermostat styles exist on these engines; compare your original thermostat port design before ordering.\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003ch4\u003eDo I need to perform a specific bleeding procedure after installation?\u003c\/h4\u003e\n\u003cp\u003eYes, you must run the automated BMW electric water pump purge cycle via the accelerator pedal sequence to eliminate trapped air pockets before starting the engine.\u003c\/p\u003e\n\n\u003ch3\u003eThe BMW Precision Standard\u003c\/h3\u003e\n\u003cp\u003eEngineered to meet stringent European tolerances, this cooling package ensures reliable communication over the vehicle CAN\/BSD data bus to eliminate fault codes and deliver track-ready thermal stability.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":67923693502712,"sku":"DS-EXYY3E4M5","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-z4-2009-2016-3-0l-1.jpg?v=1793568858","url":"https:\/\/performancechiptuning.com\/fr\/products\/performance-water-pump-kit-for-bmw-z4-2009-2016-3-0l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
