The oil drain plug on a 2013 Honda Accord uses a 14 mm hex socket. The threads are typically M14x1.5, and this size is standard across the 2.4L inline-four and the 3.5L V6 engines used in that model year.
In this article, we explain the exact plug size, where to locate it on the oil pan, and practical steps for a safe oil change, including torque guidance and washer considerations.
Plug size and thread details
The drain plug is designed with a 14 mm hex head and standard M14x1.5 threads, a common combination for Honda’s engines from this era. This covers the two main engines offered in the 2013 Accord: the 2.4L I4 and the 3.5L V6.
Knowing this helps you select the right tools and replacement parts (socket, thread dimensions, and washer) before starting an oil change.
- Socket size: 14 mm
- Thread size: M14x1.5
- Applicable engines in 2013 Accord: 2.4L I4 and 3.5L V6
When replacing the drain plug, use a new washer and ensure compatibility with the plug if you change to an aftermarket part. Honda often specifies a copper washer that should be replaced at every drain.
Oil change procedure and torque guidance
Below are the practical steps and considerations for performing an oil change on a 2013 Accord, focusing on the drain plug size and proper torque along with general safety tips.
Note: Torque specifications for the drain plug can vary by engine variant and service manual. For many Honda engines of this era, the recommended range is roughly 20-30 Nm (15-22 ft-lb); always confirm the exact value in the owner's manual or service manual for your engine code (K-series 2.4L or J-series 3.5L).
- Warm the engine to help drain oil and prevent seizing the plug; place the drain pan beneath the pan.
- Use a 14 mm socket to loosen the drain plug counterclockwise, and drain the oil completely.
- Inspect the drain plug and cooling washer for wear; replace with a new washer (and plug if damaged).
- Reinstall the drain plug by hand first, then torque to the recommended specification using a torque wrench in the 14 mm socket.
- Refill with the correct oil grade and quantity, run the engine, check for leaks, and top off as needed.
Following these steps helps ensure a proper seal and a clean oil change, minimizing the risk of leaks or overtightening damage.
Additional considerations
If the drain plug is difficult to remove, apply penetrating oil and allow time to soak, then try again with steady, even pressure. Do not exceed the manual's torque specification, as overtightening can damage the oil pan threads or drain plug.
Summary
In summary, the oil drain plug on a 2013 Honda Accord uses a 14 mm hex head with M14x1.5 threads. Use a new crush washer when replacing and follow the service manual for the exact torque specification, which typically falls in the 20-30 Nm (15-22 ft-lb) range depending on the engine code. When in doubt, reference the owner’s manual or a service manual for your exact engine variant.
