Parts for your 2010 Nissan X-trail-Sump plug washers

2010 Nissan X‑Trail Sump Plug Washers

Based on Nissan’s own technical literature, a sump plug washer is absolutely used on the 2010 Nissan X‑Trail (T31). The Nissan X‑TRAIL T31 Service Manual (Engine Mechanical section) specifies refitting the engine oil drain plug “with a new washer,” and the Periodic Maintenance (MA) section reiterates renewal at oil service. This applies across the common 2010 X‑Trail engines (MR20DE 2.0 petrol, QR25DE 2.5 petrol, and M9R 2.0 diesel). Parts catalogues for T31 list a dedicated drain plug gasket/washer for the sump, confirming it’s a fitted, service-item component.

On the 2010 X‑Trail, the sump plug washer (also called a drain plug gasket or crush washer) does the quiet, important job of sealing the drain plug against the alloy sump. It’s a soft aluminium or copper ring designed to deform slightly when tightened, creating a leak‑free seal without needing excess force. Because it crushes to seal, it’s considered single‑use. Reusing an old washer is a common cause of weeping oil, stained driveways, and that annoying burning‑oil smell on a hot exhaust.

As part of routine servicing, the washer should be replaced at every oil change. That’s why reputable workshops include a fresh washer in the service kit. The mechanic will wipe the sump face clean, thread in the plug by hand to avoid cross‑threading, then tighten to the spec for the specific engine (commonly around the low‑30s N·m, always check the service data for your engine code). No need to lean on a breaker bar—over‑tightening can crush the washer unevenly or damage the sump threads.

If DIY servicing the X‑Trail, keep a couple of correct‑size washers on hand. Choose a quality aluminium or copper washer sized for the Nissan plug. Signs it’s time to pay attention include a damp ring around the plug after a service, or a plug that only seals when overtightened. If caught short, an old washer might be flipped for a temporary seal—but that’s a stop‑gap fix. The right move is fitting a new washer, torqued correctly, and checking for any seepage after the first drive.

• Replace the washer at every oil change.
• Clean mating surfaces and torque to spec for your engine.
• Dispose of used oil responsibly at your local facility.

Does the 2010 X‑Trail need a new sump plug washer every oil change?

Yes. Nissan’s service guidance calls for installing the drain plug with a new washer. Because it’s a crush‑type seal, it’s designed for single use. Skipping it often leads to small leaks and extra mess.

What size washer suits the 2010 X‑Trail?

Most T31 X‑Trail engines use a Nissan‑spec crush washer sized for the factory drain plug. Many are 14 mm internal diameter, but variants exist. The safest bet is to match by VIN or engine code, or use a genuine‑spec washer from a trusted parts counter.

Can a copper washer be used instead of aluminium?

Both aluminium and copper crush washers are commonly specified. Use a quality washer that matches the plug size and OEM specification. If swapping material, ensure proper torque and check for leaks after the first heat cycle.
