Step-by-Step Instructions

Preparing for the Oil Change

Step 1: Vehicle Elevation

  • If you have ramps, drive your car onto them. If using jackstands, safely lift the car, ensuring it’s securely supported.

Step 2: Loosening the Oil Drain Bolt

  • Use a 14mm socket to loosen the oil drain bolt located on the rearward side of the oil pan. Do not remove it yet.

Step 3: Positioning and Draining

  • Place an oil catch can under the car and remove the drain bolt, allowing the oil to drain. Remove the oil filler cap to facilitate drainage.

Changing the Oil Filter

Step 4: Accessing the Oil Filter

  • The oil filter is on the passenger side behind a plastic shield. Remove the shield by taking out 5 plastic pop rivets.

Step 5: Removing and Installing the Oil Filter

  • Use a counterclockwise motion to remove the old oil filter. Place the new filter, lubricating its rubber gasket, and hand-tighten it. Reinstall the plastic shield.

Refilling with New Oil

Step 6: Pouring in New Oil

  • Use a funnel to pour 4.5 quarts of 0W-20 oil into the engine. Replace the oil filler cap.

Step 7: Checking for Leaks

  • Start the engine and let it idle. Check for leaks around the oil filter and oil pan bolt. If no leaks are found, lower the car off the ramps or jack stands.

Step 8: Verifying Oil Level

  • Turn off the engine, check the oil level using the dipstick, and add oil if necessary.

Final Steps and Environmental Considerations

Step 9: Recycle Used Oil

  • Properly dispose of used oil at a recycling center to protect the environment.
