⚠️ Safety & Precautions

• ⚠️ Work on level, solid ground and never crawl under a vehicle supported only by a jack.
• 🧤 Warm oil can burn skin. Let the engine cool until the oil is warm, not hot.
• 🛑 Use the specified front-center lifting point and support both sides at the reinforced front support points.
• 🔒 Keep the transmission in Park and apply the parking brake.
• 🔋 Battery disconnection is not required for this service.
• ♻️ Collect all used oil and take it to an authorized recycling facility. Never pour it onto the ground or into a drain.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Open the Engine Compartment

• 🧤 Put on the nitrile mechanic gloves and safety glasses.
• 🖐️ Open the hood, remove the oil-filler cap by hand, and place it somewhere clean.
• 🧻 Pull out the dipstick by hand and wipe it with a shop towel. Leave it partially inserted so the crankcase can vent.

Step 2: Raise and Support the Front

• 🛞 Position the 3-ton floor jack beneath the specified front-center lifting point and raise your Sienna.
• 🔒 Place the 3-ton jack stands beneath the reinforced front support points, then lower the vehicle onto them.
• ✋ Push gently on the body to confirm it is stable before going underneath.
• Never place stands beneath plastic panels.

Step 3: Remove the Oil-Service Access Panel

• 🔧 Use the 10mm socket, 3/8-inch-drive extension, and ratchet to remove the fasteners securing the oil-service panel or necessary lower-engine-cover section.
• 📦 Place the fasteners in a small, safe area so none are lost.
• 👀 Confirm that the drain plug and cartridge filter housing are accessible.

Step 4: Drain the Used Engine Oil

• 🛢️ Position the 8-quart drain pan beneath the engine oil-pan drain plug.
• 🔧 Use the 14mm socket and ratchet to loosen the drain plug. Finish removing it carefully by hand.
• ⚠️ Move your hand away as the plug releases because warm oil exits quickly.
• ⏳ Allow the oil to drain until it slows to an occasional drip.
• 🧻 Clean the drain plug with a shop towel and remove the old gasket by hand.
• 🔩 Install one new drain-plug gasket, then start the plug several turns by hand to prevent crossed threads.
• 📐 Use the 14mm socket and torque wrench to tighten the drain plug to 40 Nm (30 ft-lbs).
• Do not reuse the crushed drain-plug gasket.

Step 5: Drain the Oil Filter Housing

• 🛢️ Reposition the drain pan beneath the black cartridge-filter housing.
• 🔧 Use the 3/8-inch-drive ratchet on the small center drain plug in the filter housing and remove it carefully.
• 🔩 Remove the old small O-ring with the plastic pick. Do not scratch the sealing groove.
• 🧰 Insert the oil filter drain adapter into the housing opening and allow the trapped oil to drain completely.
• 🖐️ Remove the drain adapter by hand after the flow stops.

Step 6: Replace the Cartridge Oil Filter

• 🔧 Fit the 64mm 14-flute filter housing socket securely over the housing, then use the ratchet and extension to turn it counterclockwise.
• 🖐️ Unscrew the housing by hand and lower it upright to avoid spilling remaining oil.
• 🧻 Pull out the old filter element by hand and clean the housing with shop towels.
• 🔩 Use the plastic pick to remove the large housing O-ring. Remove only the O-ring located in its groove; do not disturb the fixed plastic ring near the housing flange.
• 💧 Coat the new large O-ring with clean 0W-20 oil and install it into the correct housing groove. Do not twist it.
• 🔩 Push the new cartridge filter element fully into the housing by hand.
• 🖐️ Thread the housing into the engine by hand until its O-ring contacts the mounting surface.
• 📐 Use the 64mm 14-flute housing socket and torque wrench to tighten the filter housing to 25 Nm (18 ft-lbs).
• 🔩 Lubricate the new small drain-plug O-ring with clean 0W-20 oil and install it on the center plug.
• 📐 Use the ratchet interface and torque wrench to tighten the center drain plug to 13 Nm (10 ft-lbs).
• Plastic housings crack easily; never overtighten.

Step 7: Reinstall the Lower Cover

• 🧻 Use shop towels to clean spilled oil from the oil pan, drain plug, filter housing, and lower cover.
• 🔧 Position the service panel and start every fastener by hand.
• 🔧 Use the 10mm socket and ratchet to tighten the panel fasteners snugly. Do not overtighten fasteners installed into plastic clips.

Step 8: Lower the Vehicle

• 🔧 Use the 3-ton floor jack to lift your Sienna slightly off the jack stands.
• 🖐️ Remove both jack stands, then lower the vehicle slowly with the floor jack.
• 🧱 Leave the wheel chocks in place until the service is complete.

Step 9: Refill the Engine

• 🛢️ Insert the oil funnel into the filler opening and add approximately 5.5 US quarts of 0W-20 oil.
• 🖐️ Remove the funnel and install the oil-filler cap securely by hand.
• 🧻 Fully insert the cleaned dipstick.

Step 10: Circulate the Oil and Check the Level

• 🚐 Start the engine and let it idle for approximately 30 seconds. The oil-pressure warning should turn off within a few seconds.
• 🛑 Shut off the engine immediately if the oil-pressure warning remains illuminated or if oil leaks underneath.
• ⏳ Switch off the engine and wait at least five minutes on level ground.
• 🧻 Remove the dipstick, wipe it with a shop towel, insert it fully, and remove it again.
• 💧 Add 0W-20 oil through the funnel in small amounts until the level is near the upper mark without exceeding it. Total capacity with filter is approximately 5.8 US quarts (5.5 liters).
• 🖐️ Reinstall the dipstick and oil-filler cap securely by hand.

Step 11: Reset the Oil Maintenance Reminder

• 🔑 Switch the ignition on without starting the engine. For push-button start, press the START button twice without pressing the brake pedal.
• 🎛️ Use the steering-wheel controls to open Settings > Vehicle Settings > Oil Maintenance.
• ✅ Select Yes to reset the oil-maintenance data.
• 📋 If a separate scheduled-maintenance reminder is displayed, select Settings > Vehicle Settings > Scheduled Maintenance > Yes.
• 🔑 Switch the ignition off after the reset confirmation appears.

✅ After Repair

• 🔍 Run the engine for two minutes and inspect the drain plug and filter housing for fresh oil leakage.
• 📏 Shut the engine off, wait at least five minutes, and check the dipstick again on level ground.
• ⚠️ Do not overfill. Oil above the upper dipstick mark must be drained to the correct level.
• 🧻 Wipe away any remaining spilled oil with shop towels.
• 📝 Record the date, mileage, oil viscosity, and filter replacement.
• ♻️ Pour the used oil into a sealed container and take the oil and used filter to an authorized recycler or service center.
