Parts for your 2018 Nissan X-trail-Sump plug washers

2018 Nissan X‑Trail sump plug washers

Yes, the 2018 Nissan X‑Trail (T32 series) uses a sump plug washer on the engine oil drain plug. Nissan’s T32 Series Service Manual (Maintenance and Lubrication sections) specifies refitting the drain plug with a new gasket/washer at each oil change and tightening the plug to 34 N·m. Genuine Nissan crush-washer part numbers commonly referenced in the Nissan EPC for this platform include 11026-01M02 and 11026-JA00A (14 mm aluminium). That tells the full story: the washer is a one-time-use sealing ring designed to prevent drips and weeps once the new oil goes in.

On the X‑Trail, the sump plug washer does a simple but vital job. It’s a soft aluminium crush washer that deforms slightly as the plug is torqued up, creating a reliable seal between the plug head and the sump. Without it, or if it’s reused too many times, owners can end up with slow oil seepage, messy undertrays, and oil smells on hot days. Keeping that washer fresh is cheap insurance for the longevity of the engine and the cleanliness of the driveway.

As part of regular servicing, it’s good practice to replace the sump plug washer every oil change. Nissan’s service literature for the T32 calls out “always replace drain plug gasket with a new one” along with the 34 N·m torque setting, so it’s not a guess—it’s the factory method. Most independent workshops in Australia and New Zealand keep the 14 mm Nissan washer on hand in copper or aluminium, aluminium is the OE style and mates perfectly with the X‑Trail’s sump.

When doing the job, a few simple habits go a long way:

• Always fit a new 14 mm crush washer (Nissan 11026‑01M02 or 11026‑JA00A equivalents).
• Clean the mating surface on the sump and the plug head so the washer can seat properly.
• Use a torque wrench and tighten to 34 N·m—over‑tightening can distort the washer or damage threads.
• After the first warm run, have a quick look under the bonnet and undertray for any tell‑tale weeping.

If there’s any uncertainty about which washer to use, a rego/VIN look‑up against the Nissan EPC will confirm the correct 14 mm size. Given the low cost, most owners are happy to throw a couple into the glovebox, so they’re never caught out on service day. Simple, tidy, and exactly how Nissan intended.
