🔩 Required Parts
HowToo sells all the parts you need for this repair:
- Engine oil (0W-20 full synthetic, dexos1-approved) - Qty: 8 quarts
- Engine oil filter - Qty: 1
- Oil drain plug gasket (if equipped/required) - Qty: 1
đź“‹ Before You Begin
- Park the Tahoe on level ground, shift to Park, and set the parking brake.
- Gather your oil and filter first so the engine isn’t left empty.
- If your Tahoe has a front lower splash shield, you may need to remove/loosen it for access.
- Know where you’ll take used oil/filter for recycling (most parts stores accept it).
🔨 Step-by-Step Instructions
Follow these steps in order:
Step 1: Warm the oil slightly
- Start the engine and let it idle 2–3 minutes, then shut it off.
- Warm oil drains faster and carries more sludge.
Step 2: Lift and support the front (if needed)
- Place wheel chocks behind the rear tires.
- Use a floor jack (rated 3-ton minimum) at the proper front lift point and raise the front.
- Set the Tahoe down onto jack stands (rated 3-ton minimum) and gently shake-test for stability.
Step 3: Remove the lower splash shield (if equipped)
- Place the drain pan (10-quart minimum) under the engine area.
- Use a 10mm socket and 3/8" drive ratchet to remove the fasteners and move the shield out of the way.
- Keep bolts in a cup so you don’t lose them.
Step 4: Drain the engine oil
- Position the drain pan (10-quart minimum) under the oil pan drain plug.
- Use a 15mm socket with a 3/8" drive ratchet to loosen the drain plug, then finish removing it by hand.
- Let the oil drain until it slows to an occasional drip (usually 10–15 minutes).
Step 5: Reinstall the drain plug
- Wipe the drain plug and the oil pan sealing surface with shop rags.
- Reinstall the plug by hand first (prevents cross-threading), then tighten with the torque wrench (3/8" drive) and 15mm socket.
- Torque to 20 Nm (15 ft-lbs)
Step 6: Remove the oil filter
- Move the drain pan (10-quart minimum) under the oil filter area (the filter will spill oil).
- Use the oil filter wrench (cap or strap style) to loosen the filter. (This tool grips the filter can so you can turn it.)
- Spin the filter off by hand and let it drain into the pan.
- Check that the old rubber gasket came off with the old filter (don’t leave it stuck to the engine).
Step 7: Install the new oil filter
- Lightly coat the new filter’s rubber gasket with a dab of new oil (use a finger).
- Spin the new filter on by hand until the gasket contacts, then tighten an additional 3/4 turn by hand.
- Hand-tight only—tools can crush the gasket.
Step 8: Reinstall the splash shield (if removed)
- Reposition the shield and start all fasteners by hand.
- Use a 10mm socket and 3/8" drive ratchet to snug the fasteners evenly.
Step 9: Refill with oil
- Lower the Tahoe off the jack stands (rated 3-ton minimum) using the floor jack (rated 3-ton minimum).
- Open the hood and remove the oil fill cap.
- Use a funnel and add 0W-20 full synthetic, dexos1-approved oil.
- Add most of the fill, then pause and check the dipstick; top off to the full mark (typical fill is about 8 quarts with filter).
Step 10: Start engine and check for leaks
- Start the engine and let it idle 30–60 seconds.
- Look underneath for leaks at the drain plug and oil filter.
- Shut the engine off, wait 5 minutes, then re-check the dipstick and top off if needed.
Step 11: Reset the Oil Life Monitor
- Turn ignition to ON (engine off), or run the engine (either works).
- Use the steering wheel controls to reach the oil life screen.
- Hold the check-mark/confirm button to reset when “Oil Life” is displayed. Confirm reset if prompted.
âś… After Repair
- Re-check for drips after your first 10–15 minute drive.
- Make sure the oil level is at the full mark on the dipstick (not overfilled).
- Pour used oil into a sealed container and recycle it; bag the old filter and recycle it too.
- If you see “Low Oil Pressure” or a loud ticking after service, shut it off and recheck oil level and filter installation.
