Over time, thermal cycling and contaminated oil score the factory aluminum pump housing and wear down the internal trochoid gear clearances. Simultaneously, the OEM oil pressure relief valve can stick or bind, causing erratic pressure drops at hot idle. Once hydraulic pressure bleeds off, secondary timing chain tensioners lose tension and connecting rod bearings run metal-to-metal, quickly leading to catastrophic bottom-end failure.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis replacement oil pump is manufactured to exacting OE tolerances to eliminate internal hydraulic bypass. Built with precision-machined gears housed within a rigid cast aluminum body, it restores positive displacement flow across all RPM bands. The assembly features a pre-calibrated pressure relief valve spring designed to prevent aeration and pressure spiking under high thermal loads. Supplied with a direct-fit replacement gasket and nitrile O-ring, it seals the front timing cover interface to prevent fluid cavitation and ensure immediate oil delivery to the valvetrain.\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 O-Ring\u003c\/li\u003e\n  \u003cli\u003e1 Front Gasket\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;\"\u003e2003-2007 Nissan Murano\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;\"\u003eVQ35DE \/ Z50\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;\"\u003e245 hp \/ 246 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;\"\u003eEA-266-41964, OP3035, 13510-31U10\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\u003e2003-2007 Nissan Murano 3.5L V6 VQ35DE\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 Z50 Murano?\u003c\/h4\u003e\n\u003cp\u003eYes, this is a direct fit for the 2003-2007 Nissan Murano equipped with the \u003cstrong\u003eVQ35DE\u003c\/strong\u003e 3.5L V6 engine.\u003c\/p\u003e\n\n\u003ch4\u003eDo I need to prime this oil pump before the first startup?\u003c\/h4\u003e\n\u003cp\u003eYes, pack or coat the internal gear cavity with clean assembly lube or engine oil prior to timing cover installation to prevent dry-friction wear and promote rapid suction on initial crank.\u003c\/p\u003e\n\n\u003ch3\u003eThe Nissan V6 Caliber\u003c\/h3\u003e\n\u003cp\u003eThe \u003cstrong\u003eVQ35DE\u003c\/strong\u003e is an award-winning high-revving architecture that demands sustained oil volume to safeguard its variable cam phasing and rod journals.
