• ⚠️ Never work beneath your Impala while it is supported only by a floor jack.
• ⚠️ Support the front of the vehicle with correctly positioned jack stands rated for its weight.
• ⚠️ Warm oil drains better, but hot oil and exhaust parts can cause burns.
• ⚠️ Wear safety glasses and nitrile gloves while working underneath the engine.
• ⚠️ Do not start the engine until the drain plug, filter, and oil-fill cap are installed.
• 🔋 Battery disconnection is not required.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Open the Hood and Remove the Oil-Fill Cap

• Pull the hood release, open the hood, and secure it fully.
• Turn the engine oil-fill cap counterclockwise by hand and remove it.
• Pull out the dipstick by hand, wipe it with a shop towel, and set it back into its tube without forcing it.
• Removing the cap helps the oil drain smoothly.

Step 2: Raise and Support the Front

• Position the floor jack at the reinforced front-center lifting point on the front cradle.
• Raise your Impala high enough to access the drain plug and oil filter.
• Position the jack stands beneath the reinforced left and right front cradle support points, then lower the floor jack slowly.
• Leave the floor jack lightly touching the cradle as a backup without lifting the vehicle off the stands.
• Push gently against the vehicle to verify it is stable before going underneath.

Step 3: Remove the Lower Access Panel if Equipped

• Look beneath the engine for an oil-service opening or lower splash shield blocking the drain plug or filter.
• Use the plastic trim tool to release any plastic retainers securing the access panel.
• Place the retainers together where they cannot be lost.

Step 4: Drain the Old Engine Oil

• Put on the nitrile mechanic gloves and safety glasses.
• Position the 8-quart oil drain pan beneath the drain plug, slightly toward the rear because the oil initially flows outward.
• Use the 15mm socket and 3/8-inch-drive ratchet to loosen the drain plug counterclockwise.
• Finish removing the plug by hand while pressing it toward the oil pan, then pull it away quickly.
• Allow the oil to drain until only an occasional drip remains, usually 10-15 minutes.
• Clean the drain plug and its seating surface with a shop towel.

Step 5: Reinstall the Drain Plug

• Remove the old drain-plug seal and fit the new seal to the cleaned plug.
• Thread the drain plug clockwise by hand until fully seated. It should turn smoothly without being forced.
• Use the 15mm socket and 3/8-inch-drive torque wrench to torque the drain plug to 25 Nm (18 ft-lbs).
• Hand-starting the plug prevents damaged oil-pan threads.

Step 6: Remove the Old Oil Filter

• Move the 8-quart oil drain pan beneath the spin-on filter at the lower front area of the engine.
• Use the spin-on oil filter wrench to loosen the filter counterclockwise.
• Finish unscrewing the filter by hand while keeping it upright as much as possible.
• Verify that the old filter’s rubber gasket came off with the filter.
• Clean the engine’s filter-mounting surface with a shop towel.
• Do not use a plastic trim tool or other hard object to scrape the sealing surface.

Step 7: Install the New Oil Filter

• Apply a light film of fresh SAE 5W-30 oil to the new filter’s rubber gasket using a gloved fingertip.
• Thread the new filter clockwise onto the engine by hand until its gasket contacts the mounting surface.
• Tighten the filter by hand an additional three-quarters of a turn unless the filter manufacturer specifies a different rotation on its label.
• Do not use the spin-on oil filter wrench to tighten the new filter.
• Overtightening makes the next filter removal difficult.

Step 8: Reinstall the Access Panel and Lower the Vehicle

• Use the plastic trim tool to reinstall the lower access-panel retainers, if removed.
• Check with the safety glasses on that no tools or containers remain beneath your Impala.
• Raise the vehicle slightly with the floor jack and remove both jack stands.
• Lower the vehicle slowly with the floor jack until all four tires are on the ground.
• Remove the rubber wheel chocks.

Step 9: Refill the Engine

• Place the engine-oil funnel in the oil-fill opening.
• Pour in approximately 5.2 liters (5.5 US quarts) of dexos1 SAE 5W-30 engine oil.
• Remove the funnel, install the oil-fill cap by hand, and fully seat the dipstick.
• Start the engine and allow it to idle for 30 seconds. The oil-pressure warning light should switch off within a few seconds.
• Switch off the engine immediately if the oil-pressure warning remains illuminated.

Step 10: Check for Leaks and Set the Final Level

• Use the safety glasses and inspect beneath the engine for leakage around the drain plug and oil filter.
• Switch off the engine and wait at least five minutes on level ground.
• Remove the dipstick by hand, wipe it with a shop towel, reinstall it fully, and remove it again.
• Use the engine-oil funnel to add oil in small amounts until the level reaches the upper crosshatched mark without exceeding it.
• The total refill capacity with a new filter is approximately 5.7 liters (6.0 US quarts).
• Reinstall the dipstick and oil-fill cap securely by hand.

Step 11: Reset the Engine Oil-Life System

• Turn the ignition on without starting the engine. For push-button ignition, press and hold the start button for about five seconds without pressing the brake pedal.
• Use the right-side steering-wheel controls to open the Driver Information Center information pages.
• Display Info Pages > Remaining Oil Life.
• Press and hold the SET/CLR or checkmark button until the display resets to 100%.
• If a confirmation prompt appears, highlight Yes and press SET/CLR or the checkmark button.
• Switch the ignition off, then turn it back on and verify that Remaining Oil Life shows 100%.

✅ After Repair

• ✅ Start the engine and verify that the oil-pressure warning light turns off normally.
• 🔍 Let the engine idle for two minutes, then check underneath for oil leaking from the filter or drain plug.
• 🧪 After a short drive, park on level ground, wait at least five minutes, and check the dipstick again.
• ♻️ Pour the used oil into a sealed container and take it with the old filter to an authorized oil-recycling facility. Do not pour oil onto the ground or into a drain.
• 📝 Record the date, mileage, oil specification, and filter replacement for your maintenance history.
