Over heat cycles, the internal pneumatic control sleeve sticks, or its internal sealing diaphragm ruptures. This mechanical degradation draws pressurized coolant directly through the vacuum lines and into the solenoid blocks, creating vacuum system faults, check engine warnings, and catastrophic loss of coolant regulation. Concurrently, thermal fatigue causes hairline fractures along the factory composite impeller and plastic thermostat mating flanges, causing coolant seepage and localized cylinder head heat soak.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis coordinated service assembly addresses every thermal weak link in the \u003cstrong\u003e4V1\u003c\/strong\u003e chassis cooling loop. Featuring a cast aluminum pump housing matched with a precision aluminum impeller, this kit resists structural warping, shaft seal deflection, and impeller cavitation under high RPM loads. The kit bundles the primary belt-driven mechanical pump, integrated thermostat, hard water transfer pipe, and brand-new pneumatic solenoid valves. Swapping the entire layout simultaneously eradicates cross-contamination within the engine vacuum network and restores precise coolant flow metering across the hybrid powertrain.\u003c\/p\u003e\n\n\u003ch3\u003eWhat's Included\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e1 Engine Water Pump Assembly with Pulley\u003c\/li\u003e\n  \u003cli\u003e1 Thermostat\u003c\/li\u003e\n  \u003cli\u003e1 Water Pipe\u003c\/li\u003e\n  \u003cli\u003e1 Pulley\u003c\/li\u003e\n  \u003cli\u003e2 Solenoid Valves\u003c\/li\u003e\n  \u003cli\u003e1 Thermal Pneumatic Valve\u003c\/li\u003e\n  \u003cli\u003eO-Ring and Fixing Bolt Hardware Set\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;\"\u003e2020-2026 Bentley Bentayga\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;\"\u003eEA839 3.0L Turbocharged V6 PHEV \/ 4V1\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;\"\u003e443 hp \/ 516 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;\"\u003e9A712101303, 9A712101304, 06M121013D, 06M121013G, 06M121013C, 06M121031D, 06M121031G, N91121903, 06M 121 013G, 9A712111511, PAB121115B, PAC121115, 06M121115, 06M121678H, 06M121678F, 06M121678G, 9A712167800, PAB121678A, 06M121115J, 06M121115G, 06M121115K, 06M121115H, 9A712111510, 06M115401K, 06M115401L, 06M115401F, 06M115401E, 9A711540100, 9A711540105, 9A711540110, PAB115401, PAC115401, 06M117015M, 9A711701530, 06M121083J, 06M121083H, 9A712108300, 9A71210830\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\u003e2020-2026 Bentley Bentayga 3.0L Plug-In Hybrid Gas Turbo V6\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 4V1 Bentayga?\u003c\/h4\u003e\n\u003cp\u003eYes, this is a direct fit for the 2020-2026 Bentley Bentayga equipped with the \u003cstrong\u003eEA839\u003c\/strong\u003e 3.0L Turbo V6 PHEV engine. \u003cstrong\u003eThis kit does not fit 4.0L V8, 6.0L W12, or earlier supercharged 3.0L configurations.\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003ch4\u003eIs this an auxiliary electric water pump?\u003c\/h4\u003e\n\u003cp\u003eNo, this is the main belt-driven mechanical water pump assembly responsible for primary engine block and cylinder head thermal management.\u003c\/p\u003e\n\n\u003ch3\u003eThe Bentley Engineering Standard\u003c\/h3\u003e\n\u003cp\u003ePrecision-engineered to meet stringent European operating requirements, this mechanical pump kit maintains factory thermal balance, guarantees leak-free sealing, and ensures zero fault codes on complex modern Bentley engine control platforms.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":68035441819896,"sku":"DS-E0E7DAPDG","price":519.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/performance-water-pump-kit-for-bentley-bentayga-2020-2026-3-0l-1.jpg?v=1794189385","url":"https:\/\/performancechiptuning.com\/fr\/products\/performance-water-pump-kit-for-bentley-bentayga-2020-2026-3-0l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
