Parts for your 2007 Nissan Maxima-Oil pump

2007 Nissan Maxima oil pump — what it does, why it matters, and when to service it

Technical sources confirm the 2007 Nissan Maxima is fitted with an engine oil pump. The Nissan Factory Service Manual for the 2007 Maxima (section LU – Lubrication System) details a crankshaft-driven trochoid (gerotor) oil pump integrated into the front timing cover on the VQ35DE 3.5‑litre V6. Nissan’s parts catalogue also lists the oil pump/front cover assembly, relief valve and pickup, and official service literature specifies oil pressure targets and pump priming procedures for this engine. So yes, the oil pump is very much relevant on this model.

On the 2007 Maxima, the oil pump’s job is to push engine oil through galleries to the crank and rod bearings, cam journals, hydraulic chain tensioners and the variable valve timing system. It builds and regulates pressure with a relief valve so the engine gets the right flow across cold starts, traffic, and motorway kilometres. Without good oil pressure, bearings wear fast, chains can rattle, and the top end gets noisy.

Day‑to‑day, the smartest “oil pump maintenance” is simply keeping oil changes on time with the correct viscosity and a quality filter. Fresh oil protects the pump’s internal rotors from scoring and keeps the pickup screen clean. For most Aussie and Kiwi conditions, the factory‑recommended 5W‑30 that meets the correct API spec is ideal, stick to the service interval in the logbook and check the level regularly.

When might the pump need attention? If the oil pressure warning lamp flickers at hot idle, there’s a brief rattle on cold start, or the engine logs variable valve timing faults, it’s worth testing oil pressure with a mechanical gauge. The VQ35DE typically shows around 100 kPa at hot idle and roughly 300–440 kPa at 2,000 rpm when healthy. If pressure is low, a worn pump, a clogged pickup, excessive bearing clearances, or a poor‑quality filter could be to blame.

• Replacing the pump is a bigger job: the front cover comes off, the crank pulley and timing chains are managed, and sealing surfaces need careful prep.
• Always prime the new pump with clean oil, fit a new front crank seal and O‑rings, and use the correct RTV on the cover.
• After reassembly, verify pressure with a gauge and use fresh oil and filter.

A trusted technician familiar with Nissan VQ engines will make light work of the process and help protect the engine for the long haul.

Is there an oil pump on the 2007 Nissan Maxima?

Yes. The VQ35DE 3.5‑litre V6 uses a crankshaft‑driven trochoid oil pump built into the front timing cover, as documented in Nissan’s 2007 Factory Service Manual and parts catalogue.

What are common signs the Maxima’s oil pump needs attention?

Warning lamp flicker at hot idle, a brief chain rattle on cold starts, ticking from the top end, or VVT‑related fault codes. Confirm with a mechanical oil pressure test before replacing parts, sometimes a blocked pickup, thin oil or a poor filter is the real culprit.

Should the oil pump be replaced as preventative maintenance?

Not usually. With regular oil and filter changes, the pump often lasts the life of the engine. Consider replacement during timing chain/front cover work on high‑kilometre cars, or if verified hot oil pressure is below spec despite correct oil and a healthy filter.
