Parts for your 2013 Nissan Serena-Oil pump

2013 Nissan Serena oil pump — what it does and when to look at replacing it

Technical sources confirm the 2013 Nissan Serena is fitted with an engine oil pump and relies on it for normal operation. The Nissan Serena C26 Factory Service Manual (FSM) lists the oil pump within the Lubrication System (LU) section for the MR20-series engine, and the Nissan FAST electronic parts catalogue also shows a pump assembly for this model. So yes—an oil pump is absolutely relevant and used on the 2013 Serena.

On the 2013 Serena, the oil pump’s job is to circulate engine oil under pressure through bearings, camshafts, the timing chain, and variable valve timing hardware. It forms the heart of the lubrication system, keeping friction down, cooling hot spots, and flushing away contaminants. Without steady oil pressure, the engine will quickly suffer wear or even catastrophic damage.

As part of regular servicing, the oil pump itself isn’t a routine replacement item. Instead, the smartest way to look after it is to keep the oil clean and at the right level. Sticking to oil and filter changes on schedule, using the viscosity and spec recommended in the owner’s manual (quality oils meeting current API/ILSAC standards), does most of the heavy lifting to protect the pump, the pickup, and the relief valve.

There are times the oil pump deserves closer attention—typically when the front timing cover is off for timing chain work, seal replacement, or major gasket resealing. That’s a good opportunity to inspect the pump housing for scoring, check rotor clearances (per FSM specs), clean the pickup strainer, and replace any O-rings or seals. If a new pump is fitted, it should be primed with clean oil before refitting, sealant applied as per the FSM pattern, and oil pressure verified with a mechanical gauge on first start.

• Common warning signs: flickering oil pressure light at idle, top-end rattle on cold start, metallic glitter in the oil, or VVT-related fault codes.
• Typical labour: replacement can be involved because the pump is driven off the crank and sits behind the front cover
