- Engine oil (0W-20 full synthetic) - Qty: 7 quarts
- Oil filter element - Qty: 1
- Oil filter housing O-ring set - Qty: 1
- Oil drain plug crush washer - Qty: 1
📋 Before You Begin
- Park your Avalon on level ground, apply the parking brake, and chock the rear wheels.
- Warm the engine for 2-3 minutes, then shut it off. Warm oil drains faster.
- Open the hood and remove the oil filler cap by hand to help the oil drain quicker.
- If you lift the front: place the floor jack at the front center jack point, then support with jack stands at the approved front side points.
🔨 Step-by-Step Instructions
Follow these steps in order:
Step 1: Access the drain plug and oil filter housing
- Raise the front of the car with a floor jack (rated 3-ton minimum) and set it securely on jack stands (rated 3-ton minimum).
- Use a 10mm socket and trim clip removal tool to remove the lower engine undercover (the splash shield) as needed to reach the drain plug and filter housing.
Step 2: Drain the engine oil
- Place the oil drain pan (10-quart minimum) under the oil pan drain plug.
- Use a 14mm socket with a 3/8" drive ratchet to loosen and remove the drain plug (turn counterclockwise).
- Let the oil drain until it slows to a drip (typically 5-10 minutes).
- Remove the old crush washer from the drain plug and install the new one.
Step 3: Reinstall and torque the drain plug
- Thread the drain plug in by hand first to avoid cross-threading.
- Use a 3/8" drive torque wrench (10-80 ft-lbs range) with a 14mm socket to tighten the drain plug: Torque to 40 Nm (30 ft-lbs).
- Wipe the area clean with shop rags.
Step 4: Replace the oil filter element (cartridge-style)
- Move the oil drain pan (10-quart minimum) under the oil filter housing (it will spill some oil).
- Use the 64mm 14-flute oil filter cap wrench (specialty) with a 3/8" drive ratchet and 3/8" drive extension (3"-6") to loosen the filter housing cap.
- Once loose, finish removing it by hand and pull out the old filter element.
- Use a small pick tool (specialty) to remove the old O-ring(s) from the filter housing cap.
- Install the new O-ring(s). Lightly coat them with fresh engine oil (0W-20 full synthetic) using a fingertip.
- Install the new filter element into the housing/cap in the same orientation as the old one.
Step 5: Reinstall and torque the oil filter housing
- Thread the filter housing cap in by hand until the O-ring seats smoothly.
- Use the 64mm 14-flute oil filter cap wrench (specialty) and 3/8" drive torque wrench (10-80 ft-lbs range) to tighten: Torque to 25 Nm (18 ft-lbs).
- Wipe the area clean with shop rags.
Step 6: Reinstall the undercover
- Reinstall the splash shield using the 10mm socket and any clips removed with the trim clip removal tool.
- Lower the car safely using the floor jack (rated 3-ton minimum).
Step 7: Refill with oil and verify the level
- Insert a funnel into the oil fill opening.
- Pour in about 6.0 quarts of engine oil (0W-20 full synthetic) first.
- Reinstall the oil filler cap by hand.
- Start the engine and let it idle for 30-60 seconds, then shut it off.
- Wait 5 minutes, then check the dipstick and top off as needed (typical fill is about 6.4 quarts with filter, but always finalize by the dipstick).
Step 8: Reset the oil maintenance reminder
- Path A (Multi-Information Display): Use steering-wheel buttons to go to Settings > Vehicle Settings > Scheduled Maintenance > Yes/Reset.
- Path B (Odometer button method): Use the dash ODO/TRIP button to select Trip A, turn ignition OFF, then press and hold ODO/TRIP while turning ignition to ON (engine off) until the reset completes.
✅ After Repair
- With the engine running, look underneath for leaks at the drain plug and oil filter housing.
- Recheck the dipstick after a short 5-10 minute drive and top off if needed.
- Dispose of used oil and the old filter at a recycling center or auto parts store (most accept it free).
