Parts for your 2001 Nissan Navara-Sump plug washers

2001 Nissan Navara sump-plug-washers — what they do and when to replace

Yes, the 2001 Nissan Navara (D22) uses a sump plug washer (also called a crush washer or drain plug gasket). Technical sources confirm it’s a fitted and serviceable item: the Nissan D22 Workshop/Service Manual (Engine – Lubrication section) specifies replacing the drain plug gasket whenever the plug is removed, Nissan’s parts catalogue lists the 14 mm drain plug gasket (commonly referenced as 11026-01M02) for the D22 oil pan, and major AU/NZ aftermarket application guides (e.g., Repco, Tridon, Ryco) all list a 14 mm aluminium/copper crush washer for the 2001 Navara.

On this ute, the sump-plug-washer sits under the engine oil drain plug and provides a reliable seal between the plug head and the sump. It’s a soft, deformable ring—usually aluminium—that compresses when the plug is torqued to spec, taking up tiny imperfections so oil can’t seep out. Without a good washer, owners can end up with annoying weeps, mess on the driveway and, worst case, gradual oil loss.

As part of routine servicing, the sump-plug-washer should be treated as a consumable. Replace it at every oil change, rather than trying to reuse a flattened or grooved old washer. They’re inexpensive, and swapping one out is a lot cheaper than chasing leaks later. For the D22, use a 14 mm ID crush washer that matches the original profile, the common Nissan OE reference is 11026-01M02, with quality aftermarket equivalents readily available across Australia and New Zealand.

When refitting the plug, start it by hand to avoid cross-threading, fit a fresh washer, and torque the plug to specification. For the D22 Navara, the workshop manual specifies tightening the drain plug to approximately 34–44 N·m. Over-tightening can distort the washer or damage sump threads, under-tightening can allow a slow seep. After the first short drive, have a quick look under the bonnet and around the sump area to make sure everything’s dry.

If there’s any sign of oil dampness around the plug after a service—especially if the washer was reused—replace the washer and retorque to spec. Drivers doing big kays on corrugated roads or towing might check more often, but for most owners it’s a simple “every oil change” job that keeps the D22’s engine tidy and happy.

Popular questions

What size sump-plug-washer does a 2001 Navara use?
For the D22 Navara, it’s a 14 mm inner diameter crush washer. Nissan’s common OE reference is 11026-01M02, and most AU/NZ parts counters will match that to an aluminium or copper equivalent. If the vehicle has had a non-standard sump or plug fitted in the past, confirm the plug thread and seat type before purchase.

How often should the sump-plug-washer be replaced?
Replace it at every oil change. The washer is designed to crush once and seal perfectly, reusing it risks small leaks. Given how affordable they are, it’s a no-brainer to fit a fresh one whenever the plug comes out.

What’s the correct torque for the 2001 Navara sump plug?
The Nissan D22 workshop manual specifies about 34–44 N·m. Always start the plug by hand, fit a new washer, then torque to spec with a torque wrench. Avoid swinging on the spanner—over-tightening can damage threads and deform the washer.
