Parts for your 2014 Nissan Pathfinder-Sump plug washers

2014 Nissan Pathfinder sump plug washers — what they do and when to replace them

Yes — the 2014 Nissan Pathfinder (R52, VQ35DE petrol) does use a sump plug washer. Technical references that call this out include the Nissan Pathfinder 2014 (R52) Service Manual, Lubrication (LU) section, which instructs to “install drain plug with new washer” and tighten to approximately 34 N·m (25 ft-lb). Nissan’s electronic parts catalogue for the R52 also lists a 14 mm aluminium “Gasket – Drain Plug” for the engine oil pan. Together, those factory sources confirm a crush-type sump plug washer is fitted and intended to be replaced when the plug is removed.

On this Pathfinder, the sump plug washer is a small, single-use seal that sits under the drain bolt on the engine’s alloy sump. Its job is simple but crucial: when the plug is torqued down, the soft aluminium washer deforms slightly to take up any tiny imperfections between the bolt head and the pan, creating a reliable, leak-free seal. Without it, even a perfectly tight plug can seep oil, making a mess on the driveway and, worse, lowering the engine’s oil level over time.

Because it’s designed to crush once, this washer should be treated as a consumable. Best practice in Australia and New Zealand workshop circles is to replace it at every oil change. It’s an inexpensive part that protects a very expensive engine. Re-using a flattened washer can lead to weeping around the plug, over-tightening to “chase” a seal, or even damage to the sump threads.

• Use the correct 14 mm aluminium crush washer (genuine or quality aftermarket) — avoid fibre, rubber, or stacking old washers.
• Clean the sump sealing face and plug head, remove old gasket residue.
• Refit the plug with a new washer and torque to about 34 N·m (25 ft-lb). Don’t lean on it with a breaker bar.
• After refilling with the correct grade and quantity of oil, run the engine, then check under the bonnet and underneath for any drips.

Handy tips: if the old washer looks embedded into the plug, replace the plug as well. Never use thread tape or sealant on the drain plug threads — the washer provides the seal. If there’s any sign of persistent weeping after a new washer and correct torque, inspect the sump face for nicks and the plug for burrs, and replace parts as needed.

Popular questions

What size sump plug washer does a 2014 Pathfinder use?
The engine oil drain uses a 14 mm internal-diameter aluminium crush washer. That’s the standard Nissan size for this model’s sump plug. Sticking with the correct 14 mm crush type ensures the plug seats properly and seals first time.

How often should the sump plug washer be replaced?
Replace it at every oil change or any time the drain plug is removed. It’s a single-use crush washer, so re-using it risks leaks or the temptation to over-tighten the plug.

What’s the correct torque for the sump plug on a 2014 Pathfinder?
About 34 N·m (25 ft-lb), as specified in the Nissan service information for the R52. Using a torque wrench helps avoid stripping threads in the alloy sump and ensures the new washer seals properly.
