Assumption: Your Avalon retains its original Toyota cartridge-filter housing and drain hardware.

Difficulty Level: Beginner | Estimated Time: 45-75 minutes

📋 Before You Begin

• 📍 Park your Avalon on level, solid ground and apply the parking brake.
• 🌡️ Run the engine for approximately three minutes, then shut it off. Warm oil drains more easily, but the exhaust should not be dangerously hot.
• 🛞 Place the vehicle ramps directly in front of the front tires. Drive up slowly, select Park, apply the parking brake, and place wheel chocks behind both rear tires.
• 📖 A cartridge filter is a replaceable paper element installed inside a reusable filter housing.
• 🧰 A torque wrench tightens a fastener to a measured amount so it is neither loose nor damaged.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Open the Engine Oil Fill Point

• 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 engine-oil dipstick by hand and wipe it with a shop towel. Leave it slightly raised so air can enter while the oil drains.

Step 2: Access the Drain Plug and Filter

• Put on safety glasses and nitrile gloves before going underneath.
• If an underbody access panel blocks the service points, use a 10mm socket, 3/8-inch ratchet, and flat plastic trim-clip tool to remove its fasteners.
• Keep each fastener with the panel so it returns to the same location.

Step 3: Drain the Old Engine Oil

• Position the 8-quart drain pan beneath the oil-pan drain plug.
• Use a 14mm six-point socket and 3/8-inch ratchet to loosen the drain plug counterclockwise.
• Finish removing the plug carefully by hand. Move your hand away as the oil begins flowing.
• Allow the oil to drain until only an occasional drip remains, usually 10-15 minutes.
• Remove the old drain-plug gasket and clean the plug with a shop towel.

Step 4: Reinstall the Oil-Pan Drain Plug

• Install one new drain-plug gasket onto the cleaned drain plug.
• Thread the plug clockwise by hand until fully seated. It should turn easily and must not be forced.
• Use the 14mm socket and 3/8-inch torque wrench to torque to 40 Nm (30 ft-lbs).
• Hand-starting prevents expensive oil-pan thread damage.

Step 5: Drain the Oil-Filter Housing

• Move the 8-quart drain pan beneath the cartridge oil-filter housing.
• Use the 3/8-inch ratchet and 3/8-inch extension to remove the small center drain plug from the bottom of the filter housing.
• Allow the housing to drain into the pan.
• Remove the old small O-ring from the center plug by hand. Lubricate the new small O-ring with clean 0W-20 oil and install it in its proper groove.
• Reinstall the center plug with the 3/8-inch extension and torque wrench. Torque to 13 Nm (10 ft-lbs).

Step 6: Remove the Cartridge Filter Housing

• Fit the 64mm 14-flute cartridge oil-filter wrench squarely onto the filter housing.
• Use the 3/8-inch ratchet and filter wrench to turn the housing counterclockwise.
• Support the housing by hand as the final threads disengage because it will contain oil.
• Pull the old paper filter element straight out of the housing by hand.

Step 7: Install the New Filter Element and O-Ring

• Remove the large old housing O-ring by hand. Do not scratch the plastic sealing surface.
• Clean the housing and its O-ring groove with shop towels.
• Lightly coat the new large O-ring with clean 0W-20 oil, then place it in the specified outer groove near the housing threads.
• Do not place the O-ring against the housing flange or twist it.
• Push the new cartridge filter element fully into the housing by hand.

Step 8: Reinstall the Filter Housing

• Thread the filter housing clockwise into the engine by hand until the O-ring contacts its sealing surface.
• Use the 64mm 14-flute cartridge oil-filter wrench and 3/8-inch torque wrench to torque to 25 Nm (18 ft-lbs).
• Do not continue tightening after the torque wrench clicks.
• One click is enough at final torque.

Step 9: Reinstall the Underbody Panel

• Use the 10mm socket, 3/8-inch ratchet, and flat plastic trim-clip tool to reinstall every removed panel fastener.
• Tighten the small panel bolts only until snug. Do not crush the plastic panel.
• Wipe the drain-plug and filter-housing areas clean with shop towels so fresh leakage will be easy to identify.

Step 10: Refill the Engine

• Place the long-neck automotive funnel in the oil-filler opening.
• Pour in approximately 6.0 US quarts of SAE 0W-20 full-synthetic oil, then remove the funnel.
• Install the oil-filler cap clockwise by hand until secure.
• Fully insert the dipstick.

Step 11: Circulate the Oil and Check for Leaks

• Confirm that no tools or towels remain in the engine compartment.
• Start the engine and let it idle for approximately 30 seconds. The oil-pressure warning light should turn off within a few seconds.
• Shut the engine off immediately if the oil-pressure warning light remains illuminated.
• Use a flashlight and visually inspect the drain plug and filter housing for fresh oil leakage.
• Shut the engine off and wait at least five minutes for the oil to return to the oil pan.

Step 12: Set the Final Oil Level

• Pull the dipstick out by hand and wipe it clean with a shop towel.
• Insert it fully, remove it again, and read the oil level.
• Add small amounts through the long-neck automotive funnel until the level reaches the upper mark without passing it.
• The approximate refill capacity with a new filter is 6.4 US quarts (6.1 liters), but the dipstick is the final authority.
• Reinstall the dipstick and oil-filler cap securely by hand.

Step 13: Lower the Vehicle

• Remove the wheel chocks from behind the rear tires by hand.
• With the area behind the vehicle clear, start the engine and slowly reverse your Avalon off the ramps.
• Park on level ground, select Park, and apply the parking brake.

Step 14: Reset the Maintenance Reminder

• Use the steering-wheel controls to display Trip A on the instrument cluster.
• Switch the ignition off.
• Press and hold the trip-reset button.
• While holding the button, press the engine switch twice without pressing the brake pedal. This turns the ignition on without starting the engine.
• Continue holding the button until the maintenance display counts down and shows zeros or confirms that the reset is complete.
• Release the button, switch the ignition off, and then start the engine normally.
