• ⬆️ Jack up the front and support it securely on jack stands at the proper lift points.
• 🧰 If your Sentra has a lower splash shield, be ready to remove the access panel/clips.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Open the fill cap and dipstick

• Open the hood and remove the engine oil fill cap by hand.
• Pull the dipstick up slightly (don’t remove it fully). This helps the oil drain smoothly.

Step 2: Remove the lower access panel (if equipped)

• Use a trim clip tool and Phillips screwdriver to remove the clips/screws for the oil service access panel.
• Set the panel and clips aside so you don’t lose them.

Step 3: Drain the old oil

• Place the oil drain pan under the oil pan drain plug.
• Use a 14mm socket with a 3/8" ratchet to loosen the drain plug, then finish removing it by hand.
• Let the oil drain until it slows to an occasional drip (usually 5–10 minutes).
• Remove the old crush washer from the drain plug and install the new oil drain plug crush washer.

Step 4: Reinstall and torque the drain plug

• Thread the drain plug in by hand first (this prevents cross-threading).
• Use a 3/8" torque wrench with a 14mm socket and tighten the plug: Torque to 34 Nm (25 ft-lbs).
• Wipe the area clean with shop towels.

Step 5: Remove the oil filter

• Move the oil drain pan
• Use the oil filter wrench (65mm cap-style) with a 3/8" ratchet to loosen the filter, then spin it off by hand.
• Check that the old rubber gasket came off with the old filter (it should not stick to the engine).

Step 6: Install the new oil filter

• Put a small dab of new oil on your finger and lightly coat the new filter’s rubber gasket.
• Spin the new filter on by hand until the gasket touches the engine surface.
• Tighten the filter an additional 2/3 turn by hand (no tools). Hand-tight prevents future leaks.

Step 7: Reinstall the access panel (if removed)

• Reinstall the panel using the trim clip tool and Phillips screwdriver.
• Make sure all clips are fully seated so the panel doesn’t flap while driving.

Step 8: Refill with oil

• Lower the car back to the ground safely (use the floor jack and remove the jack stands).
• Place a funnel in the oil fill opening.
• Pour in about 3.8 liters (4.0 quarts) of 0W-20 full synthetic first.
• Reinstall the oil fill cap by hand.

Step 9: Start, check for leaks, and set the final oil level

• Start the engine and let it idle for 30–45 seconds.
• Shut it off and wait 2–3 minutes for oil to settle.
• Check underneath for leaks at the drain plug and oil filter.
• Pull the dipstick, wipe it with shop towels, reinsert fully, then recheck.
• Add oil in small amounts until the level is near the top mark (do not overfill).
