What size is a Honda oil drain plug?

The standard size of a Honda oil drain plug is 17 mm. This is the most common size used across Honda's vehicle lineup, though some models may have slightly different sizes. The oil drain plug is a crucial component that allows you to easily change the engine oil in your Honda vehicle.


Understanding the Oil Drain Plug Size


The oil drain plug is located at the bottom of the oil pan and is responsible for allowing the old oil to drain out when performing an oil change. Honda typically uses a 17 mm hex head oil drain plug, which is a standard size found in many vehicles. This size allows for easy removal and reinstallation of the plug using a 17 mm wrench or socket.


It's important to note that while 17 mm is the most common size, some Honda models may use slightly different sizes, such as 19 mm or 14 mm. It's always best to consult your owner's manual or check the size of the existing plug before attempting an oil change to ensure you have the correct replacement part.


Replacing the Oil Drain Plug



  • Locate the oil drain plug, usually at the bottom of the oil pan.

  • Use a 17 mm wrench or socket to loosen and remove the plug.

  • Allow the old oil to fully drain from the oil pan.

  • Clean the threads on the oil pan and the plug to ensure a proper seal.

  • Apply a small amount of thread sealant or oil to the threads of the new plug.

  • Reinstall the plug and tighten it securely, but do not overtighten.

  • Check for any leaks after the oil change is complete.


Replacing the oil drain plug is a straightforward task, but it's important to use the correct size to ensure a proper fit and prevent any leaks. Always refer to your Honda's owner's manual or consult a professional if you're unsure about the specific size or procedure.
