The drain plug is located on the bottom of the oil pan, accessible from underneath the truck.
For a 2018 F-150 equipped with the 5.0-liter V8, the oil pan sits beneath the engine at the front of the vehicle. The drain bolt is a hex-headed bolt on the pan itself, typically near the pan’s lowest point and roughly toward the middle of the engine. You’ll need to slide under the truck with a drain pan ready to catch the oil and a 14mm socket to loosen the plug.
Finding the drain plug on the 5.0L F-150
To locate it, position yourself under the front portion of the vehicle and look for a single hex-head bolt protruding from the bottom of the oil pan. The pan is the metal tray attached to the bottom of the engine; the drain plug sits in a recessed area or on the pan’s edge, and it points downward when viewed from beneath.
Tools and safety you should have
Before you begin, gather these items and observe basic safety practices:
- 14mm socket or wrench set for the drain plug
- Appropriate size drain pan to catch old oil
- Shop rags and a funnel for refilling oil
- New washer or crush washer (if your plug uses one)
- Gloves and eye protection
- Jack stands or ramps for undercar access (vehicle should be on level ground and the engine cool)
With the right tools and precautions, you’ll minimize spills and protect the engine components during the oil change.
Step-by-step draining procedure
Follow these steps to safely drain the old oil from the 5.0L F-150’s oil pan:
- Warm up the engine briefly, then turn it off and let it cool to avoid hot oil burns.
- Secure the vehicle on level ground, engage the parking brake, and place chocks on the wheels. Slide under the front half of the truck with the drain pan positioned under the oil pan.
- Use a 14mm socket to loosen the drain plug a few turns, then back it out by hand once the oil begins to flow.
- Allow the oil to drain completely into the pan. This may take several minutes; avoid removing the plug too quickly to prevent splashing.
- Reinstall the drain plug with a new washer if required, and tighten to the manufacturer’s recommended torque (usually snug plus a small fraction turn; do not overtighten). Clean any drips.
- Reposition the drain pan, then remove the floor jack or ramps and proceed with oil filter removal and replacement as part of the full oil-change procedure.
After these steps, you’ll be ready to refill with fresh oil and complete the service.
Post-drain notes and best practices
Once the drain plug is secured, remember to:
- Replace the oil filter as part of the oil-change service.
- Refill with the correct oil type and capacity for the 5.0L engine; consult the owner’s manual for exact specifications.
- Check for leaks around the drain plug after starting the engine and running it briefly.
Following these practices helps ensure a clean drain and a reliable oil change for your 2018 F-150’s 5.0L V8.
Summary
The oil drain plug on a 2018 Ford F-150 with the 5.0L V8 sits on the bottom of the oil pan and is accessible from beneath the vehicle. Use a 14mm socket, have a washer if required, and follow a careful sequence to drain, reseal, and refill oil. Always consult the owner’s manual or a Ford service manual for exact torque specs and oil capacity to ensure a proper, up-to-date maintenance procedure.
