Parts for your 2018 Nissan Serena-Oil pump

Understanding the Oil Pump in the 2018 Nissan Serena

The oil pump is a crucial component in almost every internal combustion engine, including the 2018 Nissan Serena. It is responsible for circulating engine oil under pressure to the rotating bearings, sliding pistons, and the camshaft of the engine. This circulation ensures that these parts are lubricated, cooled, and protected from wear and tear, helping the engine to operate smoothly and efficiently.

In the case of the 2018 Nissan Serena, which typically features a 2.0-litre MR20DD petrol engine or a 2.0-litre dCi diesel engine depending on the market, the oil pump is definitely present and plays a vital role. Without an oil pump, engine oil cannot travel throughout the engine, which means moving parts will run dry, overheating and accelerating wear, leading to potential engine failure.

The oil pump in the Serena is usually a gear-type pump, driven by the engine's camshaft or crankshaft. It pressurises the oil from the sump and sends it to all necessary parts of the engine, maintaining continuous lubrication. This not only prevents damage but also helps in cooling the engine components and removing contaminants by ensuring oil flows through the oil filter.

Given how essential the oil pump is, maintaining it is a key part of servicing your 2018 Nissan Serena. Regular oil changes using the correct oil grade are the first step in protecting the oil pump and the engine. Dirty or degraded oil can increase the wear on the oil pump's internal components, reducing its effectiveness over time. This can lead to lower oil pressure and the risk of oil starvation to the engine's moving parts.

When servicing the Serena, mechanics will often monitor the oil pressure as an indicator of the health of the oil pump. Low oil pressure can signal issues such as worn gears in the pump, blockages, or leaks within the oil circuits. Maintaining good oil pressure keeps the engine running efficiently and reduces the chances of major repairs down the track.

Occasionally, the oil pump itself might need to be replaced. This tends to be more common in vehicles with higher mileage or if the engine has suffered from poor maintenance or oil neglect. Replacement involves draining the engine oil, removing engine components to access the pump, and fitting a new oil pump. Because this procedure is quite involved, it is typically a job for an experienced mechanic or Nissan specialist.

To avoid oil pump failure or premature wear in a 2018 Nissan Serena, owners should:

• Stick to regular oil change intervals as recommended by Nissan, usually every 10,000 to 15,000 kilometres or annually, whichever comes first.
• Always use high-quality, manufacturer-approved engine oil that suits the local climate and driving conditions.
• Keep an eye on the oil pressure warning light and address any alerts immediately.
• Have a professional inspect the oil pump and related components if there are symptoms such as drop in oil pressure, unusual engine noises, or overheating.

The oil pump is a silent workhorse tucked inside the engine but its contribution is massive. By ensuring the oil pump is working correctly and the engine oil is clean and at the right level, the 2018 Nissan Serena will continue to deliver reliable performance and smooth running for many kilometres to come.

In short, the oil pump in the Nissan Serena is vital for engine longevity and efficiency. It should never be overlooked during servicing, even though it is an internal component not often visible to the owner. Good maintenance routines and prompt attention to oil system issues will help keep the oil pump and the engine in peak shape, giving peace of mind for daily drives and holidays alike.
