OEM water pumps rely on composite plastic impellers that suffer chemical and thermal embrittlement over time, causing them to crack, shear from the shaft, or disintegrate without warning. Concurrently, the stock plastic thermostat housing warps and develops micro-fractures along the mounting ears and sensor ports under repeated heat cycles. When either component degrades, coolant circulation drops instantly, creating localized hot spots in the aluminum cylinder head that quickly cause warped decks and blown head gaskets.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis cooling refresh kit addresses these structural vulnerabilities by pairing a robust, mechanical belt-driven water pump with an upgraded thermostat housing assembly. The water pump features a cavitation-resistant impeller secured to a case-hardened steel bearing spindle to prevent shaft slip and blade disintegration under high RPM. The matched housing assembly integrates a factory-calibrated thermostat and pre-installed sensor connector, delivering a direct-fit seal, precise thermal regulation, and total resistance to pressure fatigue.\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 Thermostat\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;\"\u003e1997-2002 BMW Z3\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;\"\u003eM52, M54, S52 \/ E36\/7\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;\"\u003e170-240 hp \/ 175-236 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;\"\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\u003eBMW Z3 2.8L Gas Naturally Aspirated — 1997-2000\u003c\/li\u003e\n  \u003cli\u003eBMW Z3 3.2L Gas Naturally Aspirated — 1998-2000\u003c\/li\u003e\n  \u003cli\u003eBMW Z3 2.5L Gas Naturally Aspirated — 1999-2002\u003c\/li\u003e\n  \u003cli\u003eBMW Z3 3.0L Gas Naturally Aspirated — 2001-2002\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 E36\/7 Z3?\u003c\/h4\u003e\n\u003cp\u003eYes, this is a direct fit for the 1997-2002 BMW Z3 equipped with the \u003cstrong\u003eM52\u003c\/strong\u003e, \u003cstrong\u003eM54\u003c\/strong\u003e, or \u003cstrong\u003eS52\u003c\/strong\u003e inline-six engine.\u003c\/p\u003e\n\n\u003ch4\u003eDo I need to bleed the cooling system after installing this kit?\u003c\/h4\u003e\n\u003cp\u003eYes, thorough manual or vacuum bleeding is mandatory to evacuate trapped air pockets from the inline-six cylinder head to prevent immediate localized overheating.\u003c\/p\u003e\n\n\u003ch3\u003eThe BMW Precision Standard\u003c\/h3\u003e\n\u003cp\u003eEngineered to meet stringent European thermal tolerances and preserve critical factory sensor integration, ensuring zero check-engine lights and reliable coolant management under aggressive driving conditions.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":67923278397688,"sku":"DS-EILJ1J5KS","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-z3-1997-2002-2-5l-2-8l-3-0l-3-2l-1.jpg?v=1793557837","url":"https:\/\/performancechiptuning.com\/es\/products\/performance-water-pump-kit-for-bmw-z3-1997-2002-2-5l-2-8l-3-0l-3-2l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
