• 📖 A crush washer is the soft metal sealing ring fitted beneath the drain-plug head; replace it at every oil change.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Open the Oil Filler

• Open the hood and locate the oil filler cap on top of the engine.
• Turn the cap counterclockwise by hand and set it on a clean shop towel.
• Pull out the yellow-handled dipstick by hand, wipe it clean, and reinstall it fully.
• Opening the cap helps the oil drain smoothly.

Step 2: Remove the Lower Access Panel

• Put on the nitrile mechanic gloves and ANSI-rated safety glasses.
• Position the 8-liter drain pan underneath the engine oil-pan area.
• If the lower splash shield blocks access, use the 10mm socket and 3/8-inch-drive ratchet to remove its bolts.
• Use the plastic trim-clip removal tool to release any retaining clips without breaking them.
• Set the panel, clips, and bolts aside in an organized location.

Step 3: Drain the Old Engine Oil

• Move the drain pan directly below the oil-pan drain plug, allowing room for the oil stream to travel outward.
• Use the 14mm socket and 3/8-inch-drive ratchet to loosen the drain plug counterclockwise.
• Finish removing the plug carefully by hand and allow the oil to drain completely for at least five minutes.
• Remove the old crush washer from the drain plug and wipe the plug clean with a shop towel.
• Inspect the plug threads. Stop if they are stripped or heavily damaged.

Step 4: Reinstall the Drain Plug

• Install one new crush washer onto the cleaned drain plug.
• Thread the plug into the oil pan clockwise by hand until fully seated. It should turn easily without binding.
• Use the 14mm socket and 3/8-inch-drive torque wrench to torque the drain plug to 34 Nm (25 ft-lbs).
• Wipe the surrounding oil-pan surface clean with a shop towel.
• Never use an impact wrench on the drain plug.

Step 5: Remove the Old Oil Filter

• Reposition the drain pan below the oil filter because additional oil will spill during removal.
• Fit the 65mm 14-flute oil filter socket over the filter.
• Use the 3/8-inch-drive ratchet to turn the filter counterclockwise until loose, then remove it by hand.
• Confirm the old rubber filter gasket came off with the filter. A gasket stuck to the engine can cause a major leak.
• Wipe the engine's filter-mounting surface clean with a shop towel.

Step 6: Install the New Oil Filter

• Apply a thin film of fresh 0W-20 engine oil to the new filter's rubber gasket using a gloved fingertip.
• Thread the new filter clockwise onto the mounting stud by hand.
• After the gasket first touches the mounting surface, tighten the filter approximately two-thirds of a turn by hand.
• If using the 65mm 14-flute oil filter socket and torque wrench, torque the oil filter to 18 Nm (13 ft-lbs).
• Do not use both tightening methods. Stop after either hand tightening or torque tightening.

Step 7: Reinstall the Lower Access Panel

• Use the plastic trim-clip removal tool by hand to reinstall the reusable retaining clips.
• Install the splash-shield bolts by hand, then snug them evenly using the 10mm socket and 3/8-inch-drive ratchet.
• Do not overtighten the small shield fasteners because the plastic mounting points can crack.

Step 8: Add Fresh Engine Oil

• Place the automotive funnel into the oil-filler opening.
• Pour approximately 4.5 liters (4.8 US quarts) of SAE 0W-20 full-synthetic oil through the funnel.
• Remove the funnel and install the oil filler cap clockwise by hand.
• Start the engine and let it idle for approximately 30 seconds. Confirm the red oil-pressure warning light turns off promptly.
• Switch off the engine and wait at least five minutes for the oil to drain back into the pan.

Step 9: Set the Final Oil Level

• Carefully drive your Pathfinder off the ramps and park it on level ground.
• Remove the dipstick by hand, wipe it with a shop towel, reinstall it fully, and remove it again.
• Check that the oil level is between the low and high marks, preferably near the high mark.
• Use the automotive funnel to add oil in 100-200 milliliter increments, checking the dipstick after each addition.
• The total fill with a new filter is approximately 4.8 liters (5.1 US quarts). Do not overfill.

Step 10: Reset the Oil Maintenance Reminder

• Switch the ignition on without starting the engine.
• Use the steering-wheel arrow and OK buttons to open Settings > Maintenance > Oil and Filter in the instrument display.
• Select Reset, then confirm with the OK button.
• If your display shows a maintenance distance setting, select the interval specified by your Nissan maintenance schedule.

• 📏 After five minutes on level ground, check the dipstick again and correct the level if necessary.
• 🧹 Pour the used oil into a sealed container and take the oil and old filter to an authorized recycling facility.
• 🔎 Recheck the oil level and inspect for seepage after the first short drive.
• 📝 Record the service date and odometer reading for future maintenance.
