Parts for your 2002 Nissan Pulsar-Sump plug washers

2002 Nissan Pulsar sump plug washers

Yes — the 2002 Nissan Pulsar (N16) uses a sump plug washer. Technical references that back this up include the Nissan Pulsar/Almera N16 Factory Service Manual (Lubrication section), which specifies a replaceable drain plug gasket for the QG-series engines used in this model year. Nissan’s parts catalogues list the drain plug gasket for the N16 as a separate service item (commonly shown under gasket–drain plug), with well-known Nissan part numbers used across many models. Independent workshop manuals for the N16 platform also instruct renewing the washer whenever the engine oil is drained. Put simply, the sump plug on a 2002 Pulsar is designed to be used with a crush-type washer.

On this Pulsar, the sump plug washer does the unglamorous but vital job of sealing the drain plug against the alloy sump. Being a soft crush washer (typically aluminium), it deforms slightly as the plug is tightened, filling tiny imperfections so oil can’t weep out. Without it — or if it’s reused too many times — there’s a risk of slow leaks, stained driveways, and a plug that needs to be over-tightened to seal, which isn’t a great idea on an aluminium sump.

As part of routine servicing, it’s smart to replace the washer at every oil change. It’s a low-cost item that helps maintain the correct torque on the plug and a clean, dry seal. The washer size matches the Pulsar’s drain plug thread (commonly an M14 plug using a 14 mm ID crush washer). Most aftermarket options specify fitment for the N16 Pulsar, sticking with an aluminium crush washer keeps things close to OEM behaviour. Copper can work too, but it’s a little harder and may need a touch more torque to seal. Fibre or bonded types aren’t typical for this application.

Good workshop practice on a 2002 Pulsar looks like this:

• Clean the sump sealing face and the plug head, then fit a brand-new washer.
• Thread the plug in by hand first to avoid cross-threading.
• Tighten to the torque specified in the Nissan service manual for the engine variant — don’t “swing off” the spanner.
• After the first heat cycle, have a quick look for any weeping and nip up only if the spec allows.

If there’s a persistent drip even with a new washer, inspect the plug for flange damage and the sump face for nicks. Replacing a scuffed plug is cheap insurance compared to repairing stripped threads.

Popular questions about 2002 Nissan Pulsar sump plug washers

What size sump plug washer does a 2002 Nissan Pulsar use?
Most 2002 Pulsar N16 engines use an M14 drain plug that takes a 14 mm inner-diameter crush washer. Parts catalogues and reputable aftermarket applications list an aluminium crush washer specifically for the N16. If in doubt, match to the existing plug or check the Nissan parts listing by VIN.

How often should the sump plug washer be replaced?
Replace it at every oil change. The washer is designed to crush once to form a perfect seal, reusing it increases the chance of weeping or needing extra torque on the plug. Given the low cost, swapping it every service is the easy, reliable option.

Is aluminium or copper better for the Pulsar’s sump plug washer?
Aluminium crush washers align best with the OEM approach on the N16 Pulsar and usually seal with the specified torque. Copper can work, but it’s harder and may require a touch more effort to achieve the same seal. Whichever material is chosen, ensure it’s the correct size and replace it each time.
