Over repeated thermal cycles, the factory rotor gear faces and inner housing walls experience micro-abrasion, increasing axial and radial clearances. Additionally, fatigue in the stock pressure relief valve spring leads to pressure bleed-off at idle. This progressive loss of hydrodynamic pressure risks rod bearing starvation, cam journal galling, and erratic operation of the variable timing (VTC) sprockets.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eEngineered to exact OEM dimensional tolerances, this oil pump assembly restores factory oil volume and hydraulic stabilization across the entire RPM range. Featuring precision-sintered gerotor gears housed within a rigid die-cast casing, it resists internal deflection and wear under sustained load. The unit incorporates a refreshed pressure relief assembly to guarantee consistent line pressure. The included high-temperature gasket and front crankshaft seal prevent front-cover fluid migration and protect against vacuum drop during cold starts.\u003c\/p\u003e\n\n\u003ch3\u003eWhat's Included\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e1 Oil Pump Assembly\u003c\/li\u003e\n  \u003cli\u003e1 Crankshaft Front Oil Seal \/ Gasket\u003c\/li\u003e\n  \u003cli\u003e1 O-Ring\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;\"\u003e2002-2008 Nissan Maxima\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\u003eVQ35DE\u003c\/strong\u003e \/ \u003cstrong\u003eA33\u003c\/strong\u003e, \u003cstrong\u003eA34\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;\"\u003e255-265 hp \/ 246-255 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\n\u003cstrong\u003eEA-266-41964\u003c\/strong\u003e, \u003cstrong\u003eOP3035\u003c\/strong\u003e, \u003cstrong\u003e13510-31U10\u003c\/strong\u003e\n\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\u003e2002-2003 Nissan Maxima 3.5L V6 (VQ35DE \/ A33B Chassis)\u003c\/li\u003e\n  \u003cli\u003e2004-2008 Nissan Maxima 3.5L V6 (VQ35DE \/ A34 Chassis)\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 A33 and A34 Maxima?\u003c\/h4\u003e\n\u003cp\u003eYes, this is a direct fit for the 2002-2008 Nissan Maxima equipped with the \u003cstrong\u003eVQ35DE\u003c\/strong\u003e engine.\u003c\/p\u003e\n\n\u003ch4\u003eDo I need to prime the oil pump prior to first engine startup?\u003c\/h4\u003e\n\u003cp\u003eYes, pre-lubricating the gerotor cavity with clean engine oil or assembly lube before installation is mandatory to establish immediate vacuum and prevent dry-start friction wear.\u003c\/p\u003e\n\n\u003ch3\u003eThe Nissan VQ Caliber\u003c\/h3\u003e\n\u003cp\u003eThe high-revving \u003cstrong\u003eVQ35DE\u003c\/strong\u003e demands uncompromising fluid delivery across its microfinished bearing journals; replacing a tired pump ensures your powertrain retains factory-rated durability and smooth high-RPM performance.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":68058926121208,"sku":"DS-EQIUFZSAX","price":83.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/oil-pump-for-nissan-maxima-2002-2008-3-5l-1.jpg?v=1794364784","url":"https:\/\/performancechiptuning.com\/products\/oil-pump-for-nissan-maxima-2002-2008-3-5l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
