🔨 Step-by-Step Instructions
Follow these steps in order:
Step 1: Remove the oil fill cap and prep the drain area
- Open the hood and remove the oil fill cap by hand.
- Set a drain pan (at least 8-quart) under the oil pan drain plug.
- Removing the cap helps oil drain faster.
Step 2: Drain the engine oil
- Use a 13mm socket with a ratchet (3/8" drive) to loosen the oil drain plug.
- Finish removing the drain plug by hand and let the oil fully drain into the pan.
- Clean the drain plug and install a new oil drain plug seal/washer if equipped.
Step 3: Reinstall and torque the drain plug
- Thread the drain plug in by hand first to avoid cross-threading.
- Use a torque wrench (3/8" drive) with a 13mm socket to tighten it.
- Torque to 25 Nm (18 ft-lbs)
- Stop if it doesn’t turn easily by hand.
Step 4: Remove the oil filter housing cap
- Locate the oil filter housing at the top of the engine.
- Use a 24mm socket with a ratchet (3/8" drive) and a socket extension (3/8" drive, 6") to loosen the cap.
- Lift the cap straight up carefully (the old filter will usually come up attached).
- Put shop towels around it for spills.
Step 5: Replace the cartridge filter and O-ring
- Pull the old cartridge filter off the cap by hand and discard it.
- Remove the old cap O-ring (a rubber seal) and install the new O-ring in the same groove.
- Lightly coat the new O-ring with fresh oil using a finger (no tools needed).
- Push the new cartridge filter onto the cap until it snaps/fully seats.
Step 6: Reinstall and torque the oil filter cap
- Thread the cap back into the housing by hand.
- Use a torque wrench (3/8" drive) with a 24mm socket to tighten the cap.
- Torque to 25 Nm (18 ft-lbs)
Step 7: Refill with fresh oil
- Insert a funnel into the oil fill hole.
- Pour in SAE 5W-20 slowly (start with about 5.5 quarts).
- Reinstall the oil fill cap by hand.
Step 8: Start, check for leaks, then set the oil level
- Start the engine and let it idle for 30-60 seconds.
- Shut it off and wait 5 minutes for oil to drain back to the pan.
- Check underneath for leaks at the drain plug and filter housing.
- Pull the dipstick, wipe it with shop towels, reinsert, then re-check.
- Add oil in small amounts until it reaches the safe/full range (don’t overfill).
✅ After Repair
- 🧪 Verify the oil level one more time after a short test drive.
- Check again for seepage around the drain plug and filter cap.
