Prepare Your Jeep Wrangler JK

3. Safety First: Engage the parking brake and block the rear wheels for extra safety.

Locate the Oil Drain Plug and Filter

1. Oil Drain Plug: Locate the oil drain plug, typically found on the bottom of the oil pan.
2. Oil Filter: The oil filter is usually located on the side of the engine, near the oil pan.

Drain the Old Oil

Replace the Oil Filter

3. Install the New Filter: Apply a thin coat of fresh oil to the rubber seal of the new oil filter. This helps ensure a proper seal. Screw the new filter on by hand until it is snug. Do not overtighten.

Add New Oil

1. Pour New Oil: Use a funnel to pour the recommended amount of new oil into the engine’s oil fill cap. Check your owner’s manual for the correct oil capacity.
