The oil drain plug on a 2014 Honda Accord uses a 14mm socket head and has an M14 x 1.5 thread. This is the standard size used on most 2014 Accord models, including the 2.4L and 3.5L engine variants.
What the size means for maintenance
Understanding the plug size helps you choose the right tool and ensure a proper seal when you change the oil. For Honda Accords from this era, the combination of a 14mm head and M14 x 1.5 thread is common, and you’ll typically replace the crush washer with a new one during each oil change to prevent leaks.
Details to know about the plug
While the 14mm head is standard, always verify the existing plug if you’re working on a non-standard model or a modified vehicle. If you can't remove the plug easily, stop and recheck the tool size or consult the owner's manual or a service guide for the exact torque specification and washer requirement.
Tools and parts you’ll need to work with the drain plug
- 14mm socket or wrench to remove the drain plug
- New copper or OEM drain plug washer (replace at every oil change)
- Torque wrench (recommended to tighten to spec)
- Drain pan, rags, and Safety equipment as needed
- Fresh engine oil and a compatible oil filter, if performing a full oil change
Using the right tools helps prevent stripping the plug head and ensures a proper seal when you reinstall it.
Here are the general steps to remove and replace the drain plug and refill the oil
- Allow the engine to cool slightly and position the vehicle on a level surface. Place a drain pan underneath the oil pan.
- Wear protective gloves and carefully loosen the drain plug with a 14mm socket, then remove it completely and let the oil drain out.
- Remove and inspect the old washer. If present, install a new copper/OEM washer on the drain plug before reinstallation.
- Reinsert the drain plug by hand to avoid cross-threading, then tighten it with a torque wrench to the manufacturer’s specification (check the owner's manual for the exact value).
- Refill the engine with the recommended oil type and quantity for your 2014 Accord, replace the oil fill cap, start the engine, and check for leaks. Recheck the oil level with the dipstick and top off if needed.
After completing the process, monitor for any signs of leakage around the drain plug area and ensure the oil level is within the correct range on the dipstick.
Summary
For a 2014 Honda Accord, the oil drain plug typically uses a 14mm head with an M14 x 1.5 thread. Always verify the plug on your exact vehicle, replace the washer at each change, and follow the manufacturer’s torque specification from the owner's manual. With the right tools and steps, the oil change can be completed cleanly and without leaks.
