Oil Pump for Nissan Murano (2003-2007) 3.5L

High-Flow Replacement Oil Pump for 2003-2007 Nissan Murano (Z50)

What it Does: The replacement oil pump maintains critical hydrodynamic lubrication throughout the 2003-2007 Murano engine assembly to restore factory oil pressure and protect internal bearings under load.

The Stock Nissan Murano Lubrication Degradation

High-mileage VQ35DE powerplants in the first-generation Z50 platform frequently suffer from internal oil pump wear. 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.

The Engineering Solution

This 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.

Frequently Asked Questions & Fitment Warnings

Does this fit the Z50 Murano?

Yes, this is a direct fit for the 2003-2007 Nissan Murano equipped with the VQ35DE 3.5L V6 engine.

Do I need to prime this oil pump before the first startup?

Yes, 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.

The Nissan V6 Caliber

The VQ35DE is an award-winning high-revving architecture that demands sustained oil volume to safeguard its variable cam phasing and rod journals. Installing an OE-specification pump restores vital operating pressure, protecting your vehicle's power delivery and long-term durability.
