Step 2: Prepare Your Vehicle

1. Park your Jeep on a level surface and engage the parking brake.
2. Allow the engine to cool down if it has been running.
3. Open the hood and remove the oil filler cap to allow oil to drain more easily.

Step 3: Drain the Old Oil

2. Position the drain pan: Place the oil drain pan under the drain plug to catch the old oil.

Remove the drain plug

• Use the 13mm socket and wrench to loosen and remove the drain plug.

Prepare the new oil filter

Step 5: Add New Oil

Pour in new oil

• Using a funnel, pour 5 quarts of new SAE 0W-20 oil into the engine through the oil filler cap.
1. Check the oil level: After adding oil, wait a minute and use the dipstick to check the oil level. Add more oil if necessary until it reaches the full mark.
