Here's a general guide, but remember to *always* prioritize your owner's manual instructions:
Tools and Materials You'll Need:
* New oil: The correct weight and type are specified in your owner's manual. Use the recommended amount.
* New oil filter: Again, check your owner's manual for the correct part number.
* Oil filter wrench: The correct size for your Expedition's oil filter. A cap-type wrench is usually best.
* Wrench for the drain plug: This is usually a 13mm or 15mm socket, but check your manual.
* Drain pan: Large enough to hold the old oil.
* Funnel: To pour in the new oil.
* Jack and jack stands (or ramps): Essential for safety. Never work under a vehicle supported only by a jack.
* Wheel chocks: To secure the vehicle.
* Gloves: To protect your hands.
* Rags or shop towels: For cleanup.
* Torque wrench: Highly recommended to tighten the drain plug to the correct specification.
Procedure:
1. Warm up the engine: Run the engine for 5-10 minutes to warm the oil, making it flow more easily.
2. Secure the vehicle: Park on a level surface, engage the parking brake, and use wheel chocks.
3. Raise the vehicle: Safely raise the vehicle using a jack and securely position jack stands under the frame. Consult your owner's manual for jack points.
4. Locate the oil drain plug: It's usually located on the bottom of the oil pan.
5. Position the drain pan: Place the drain pan under the drain plug.
6. Remove the drain plug: Carefully loosen and remove the drain plug with the appropriate wrench. Be careful, as the oil will be hot. Let the oil drain completely – this may take 15-20 minutes.
7. Replace the drain plug: Once the oil has drained, reinstall the drain plug and tighten it to the correct torque specification (found in your owner's manual). Do not overtighten.
8. Locate the oil filter: It's usually near the oil drain plug.
9. Remove the oil filter: Use the oil filter wrench to loosen and remove the old oil filter. Have a drain pan handy, as some oil will spill out.
10. Lubricate the new filter's gasket: Lightly lubricate the rubber gasket on the new oil filter with fresh oil.
11. Install the new oil filter: Screw on the new oil filter by hand until it's snug. Then tighten it according to the manufacturer's instructions (usually about ¾ to 1 full turn after it contacts the engine block).
12. Lower the vehicle: Carefully lower the vehicle using the jack.
13. Add new oil: Using the funnel, pour the correct amount of new oil into the engine (specified in your owner's manual).
14. Check the oil level: Use the dipstick to check the oil level. Add more oil if necessary to reach the "full" mark.
15. Start the engine: Run the engine for a few minutes.
16. Check for leaks: Inspect the area around the drain plug and oil filter for any leaks.
17. Check the oil level again: After running the engine, turn it off and wait a few minutes before checking the oil level again. Add more oil if needed.
18. Dispose of used oil properly: Take the used oil to a recycling center or auto parts store that accepts used oil.
Important Safety Precautions:
* Always use jack stands. Never work under a vehicle supported only by a jack.
* Hot oil can cause serious burns. Allow the oil to cool before handling.
* Wear gloves and eye protection.
* Work in a well-ventilated area.
This is a general guide. Refer to your Ford Expedition's owner's manual for specific instructions and torque specifications. If you're unsure about any part of this process, it's best to have a qualified mechanic perform the oil change.
