Parts for your 2013 Nissan Pulsar-Oil pump

2013 Nissan Pulsar Oil Pump

Yes—an oil pump is fitted to the 2013 Nissan Pulsar. Nissan factory service information for the C12 hatch and B17 sedan shows an engine‑driven trochoid (gerotor) oil pump integrated into the timing chain/front cover on HR16DE, MR18DE and MR16DDT engines. See: Nissan Engine Mechanical and Lubrication System (EM/LU) sections for C12/B17 Pulsar, the HR16DE and MR18DE FSMs, and the MR16DDT coverage in related Nissan platforms (e.g. Juke F15) which use the same architecture. These documents describe oil pump inspection, removal/installation and pressure specs—confirming the part is present and serviceable.

The oil pump on a 2013 Pulsar quietly does the heavy lifting—circulating oil under pressure so bearings, cams, chains and (on SSS/DIG‑T) the turbo stay happy. It builds pressure quickly after start‑up, pushes heat away from hot spots, and carries fine debris back to the filter. Without solid oil pressure, the engine wears fast, runs noisy and risks serious damage.

For routine servicing, the smartest move is clean oil and the right viscosity for local temps—typically a quality 5W‑30 meeting the Nissan spec in the owner’s manual. In Aussie and Kiwi conditions, many owners stick to 10,000 km or 12 months, whichever comes first, and always use a decent filter with an anti‑drainback valve. That habit protects the pump’s internal rotors and pressure relief valve from sludge and varnish.

Keep an eye out for red flags:

• Oil pressure lamp flickering at hot idle
• New rattles from the timing chain area, or lifter/tappet noise
• Knock on cold start, metallic glitter in oil, or rising engine temps
• On MR16DDT SSS, increased turbo whine after hot runs

If the lamp glows or a gauge shows low pressure, stop driving and test with a mechanical gauge. If pressure’s low and oil level/viscosity and the filter check out, the pump, pickup O‑ring, or relief valve may be tired.

Replacing the oil pump on a Pulsar is a front‑cover job. It typically involves draining the oil, removing auxiliary belts and crank pulley, unsealing the timing/front cover, and renewing the pump assembly or internals. Expect new seals and RTV, and often a sump drop to reseal. A pro will also inspect the chain, guides, tensioner and pickup screen, and will prime the pump and prelube the engine before first start. On higher‑kilometre cars, it’s smart to do the front crank seal and any brittle O‑rings while you’re there.

Get torque specs and sealant patterns from the Nissan EM/LU sections for your exact engine code. Proper priming and correct sealant use are crucial to avoid air leaks and pressure loss.

Popular questions about 2013 Nissan Pulsar oil pumps

What oil viscosity works best for a 2013 Pulsar in Australia or New Zealand?

Nissan commonly specifies 5W‑30 meeting the required performance standard for HR16DE, MR18DE and MR16DDT engines. In hotter regions or with higher mileage, some workshops use 5W‑40. Stick with the spec in the handbook or the Nissan service manual for your engine code, and change oil and filter every 10,000 km/12 months to keep pump internals clean.

How can someone tell if the oil pump is failing?

Warning lamp flicker at hot idle is the big clue, followed by top‑end rattle, chain noise, or low readings on a mechanical gauge. Before blaming the pump, verify oil level and condition, check the filter, and rule out a faulty pressure switch. If pressure is genuinely low, inspect the pickup O‑ring, relief valve and pump clearances.

Does a replacement oil pump need priming?

Yes. The pump should be packed or filled with clean oil during assembly, and the engine pre‑lubed before first start. Crank with ignition disabled to build pressure, then start and confirm pressure immediately. This avoids dry running and protects bearings and the turbo (where fitted).
