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
