Parts for your 2004 Nissan X-trail-Sump plug washers

2004 Nissan X‑Trail sump plug washers

Yes, the 2004 Nissan X‑Trail (T30) does use a sump plug washer. This is confirmed in the Nissan X‑TRAIL T30 Series Service Manual (MA — Maintenance, Engine Oil), which instructs replacing the drain plug gasket whenever the plug is refitted, and in the Nissan FAST electronic parts catalogue that lists a 14 mm drain plug gasket for the model. Genuine Nissan part numbers commonly referenced are 11026‑01M02 and 11026‑4N200 (14 mm aluminium crush washer). These sources make it clear the washer is a standard, single‑use sealing item on both the QR25DE petrol and YD22 diesel variants.

On the 2004 X‑Trail, the sump plug washer (also called a crush washer) does the quiet but vital job of sealing the oil drain plug to the sump. When the plug is torqued, the soft aluminium or copper washer deforms to fill tiny imperfections between the plug face and the sump, stopping weeps and protecting the threads from over‑tightening. It’s a cheap, sacrificial seal designed for one go — reuse can lead to slow leaks, drips on the driveway, or the temptation to swing the spanner harder than the sump threads can handle.

Best practice on this X‑Trail is to replace the washer at every oil change. Nissan’s T30 service information specifies fitting a new drain plug gasket and tightening the plug to spec (around 34 N·m/25 ft‑lb for the QR25DE petrol, check the exact figure for your engine variant). That way, the plug seals properly without needing gorilla strength, and the sump stays dry between services.

Handy servicing tips:

• Always remove the old washer — they can stick to the sump. Clean the mating face before refitting.
• Use the correct size: typically 14 mm internal diameter for the T30. Genuine Nissan 11026‑01M02/11026‑4N200 or a quality equivalent (aluminium or copper) works a treat.
• Don’t stack washers, and don’t reuse a crushed one. It’s a one‑time seal by design.
• If there’s any weeping after an oil change, check torque first, then replace the washer again if needed.

A fresh washer each service is cheap insurance against leaks, stripped threads, and messy undertrays — exactly what’s wanted on an X‑Trail that’s expected to cruise long Kiwi and Aussie kilometres without dramas.
