The oil drain plug on a 2010 Honda Accord is best removed with a 14mm socket or wrench. If you don’t have metric tools, a 9/16-inch wrench or socket can serve as a fallback, but 14mm is the standard and recommended choice.
This article explains the correct wrench size and how to use it when performing an oil change on a 2010 Accord, along with practical tips for common issues that DIYers may encounter.
Correct wrench sizes
Use the size that most closely fits the drain plug hex to avoid rounding or stripping. The following options are commonly compatible with the 2010 Accord’s oil drain plug:
- 14mm socket or combination wrench (preferred)
- 9/16 inch socket or wrench (acceptable only if 14mm is unavailable; may be a loose fit on some plugs)
Choosing the right size helps protect the drain plug and Pan threads, making removal and reinstallation more reliable.
How to perform the oil drain and plug reinstallation
Follow these steps to drain the old oil and reinstall the drain plug correctly:
- Position the vehicle safely and place a drain pan beneath the oil pan.
- Attach the correct wrench to the drain plug and turn counterclockwise to loosen.
- Allow the oil to drain completely, then wipe the plug and the sealing surface clean.
- Reinstall the drain plug with the appropriate washer as required and tighten to the vehicle’s specified torque using a torque wrench; always refer to the owner's manual for the exact figure.
Using the proper torque helps prevent leaks and ensures a reliable seal after an oil change.
Notes on issues and alternatives
If the drain plug is stubborn or the washer is damaged, avoid forcing the plug, which can strip threads. Apply penetrating oil and reattempt after a soak, or seek professional assistance to protect the pan and threads.
Summary: For a 2010 Honda Accord, the standard wrench size for the oil drain plug is 14mm, with 9/16 inch as a fallback if 14mm tools are not available. Always use the correct washer and torque specification from the owner’s manual when reinstalling.
Summary
In practical terms, grab a 14mm socket or wrench for most 2010 Honda Accords. If missing, a 9/16" tool can work, but aim to use 14mm to minimize risk. Never skip replacing the washer or skipping torque specifications; follow the owner’s manual for final tightening to complete a safe, leak-free oil change.
