Parts for your 1995 Nissan Primera-Sump plug washers

1995 Nissan Primera sump plug washers — what they do and when to replace them

Yes, the 1995 Nissan Primera does use a sump plug washer. Nissan’s factory documentation for the P10-series Primera (1990–1996) specifies a drain plug sealing washer that must be renewed at each oil change, and gives a tightening torque of roughly 34–44 N·m for the oil drain plug. Nissan’s FAST parts catalogue also lists the “Gasket – Drain Plug, Engine Oil” for P10 models (common genuine part numbers include 11026-01M02 and its supersession 11026-4N200), typically a 14 mm aluminium crush washer. Haynes service literature covering Primera models of this era repeats the same “fit a new sealing washer” guidance.

On this Primera, the sump plug washer’s job is simple but critical: it crushes slightly as the drain plug is tightened, creating a reliable seal between the plug head and the sump. That stops slow weeps that can leave spots on the driveway, lower the oil level, and make a mess under the bonnet. Because it’s a crush-type seal, it’s designed for single use. Re-using a flattened or gouged washer risks leaks even if the plug feels tight.

Best practice for servicing a 1995 Primera is to replace the washer at every oil change. Most owners in Australia and New Zealand work to around 10,000 km or 12 months, but follow the service schedule for the specific engine (GA16, SR18, SR20, or CD20 diesel). A fresh, correct-size aluminium (or copper, where specified) washer costs next to nothing and helps protect the sump threads from over-tightening.

Handy tips for a tidy job:

• Use the right washer size: typically 14 mm ID for the Primera’s M14 drain plug.
• Clean the sump’s sealing face and the plug head before refitting.
• Tighten to the Nissan spec of 34–44 N·m. Going by feel with a long bar can strip threads, a torque wrench keeps it safe.
• If the old washer stuck to the sump, carefully remove it without scratching the surface.
• A smear of clean engine oil on the new washer helps it seat smoothly—skip sealants or tape.

If there’s any sign of oil mist around the plug after an oil change, check that the correct new washer was used and torque is within spec. With the right washer fitted, the 1995 Primera’s sump stays clean, dry and ready for the next long run.

Popular questions

What size sump plug washer does a 1995 Nissan Primera use?
Most 1995 Primera engines use a 14 mm aluminium crush washer on the M14 drain plug. Nissan genuine options commonly reference part numbers 11026-01M02 or 11026-4N200. Always match by engine/VIN if unsure.

How often should the sump plug washer be replaced on a 1995 Primera?
Replace it at every oil change. The washer is a crush type and is intended for single use. Fresh oil, a new filter, and a new washer keep the seal sound and help avoid sump thread damage from over-tightening.

What torque should the sump plug be tightened to?
Nissan service information for the P10 Primera specifies about 34–44 N·m for the drain plug. Many techs aim near the middle (around 39 N·m). Using a torque wrench is the safest way to hit the target without stressing the sump.
