On the 2017 Honda Pilot, the oil drain plug requires a 14 mm socket. This size applies to the 3.5-liter V6 engine common in that year.
Beyond the socket size, the drain plug sits at the bottom of the oil pan and typically uses a copper crush washer that should be replaced when reassembling. Always consult the owner's manual for the exact torque specification and use a torque wrench to avoid overtightening.

- Warm the engine to circulating temperature, then park on level ground and engage the parking brake.
- Place the oil drain pan under the oil pan and locate the drain plug at the bottom of the pan.
- Using a 14 mm socket, carefully loosen and remove the drain plug, allowing the oil to drain fully into the pan.
- Inspect the drain plug and replace the copper washer if necessary, then reinstall the drain plug and tighten to the manufacturer’s specified torque with a torque wrench.
- Remove the old oil filter (if performing a full change), install a new filter, and refill the engine with the recommended oil quantity and grade.
- Start the engine, check for leaks around the drain plug, and recheck the oil level after the engine has run and settled.
By following these steps, you can complete a standard oil drain and refill while maintaining proper sealing and levels. Always dispose of used oil at an authorized facility.
