Oil drain plugs for the Honda Accord come in different sizes, with the most common thread sizes being M14x1.5 and M20x1.5. Using the correct size plug is crucial for ensuring a proper seal and preventing leaks during an oil change.

Common thread sizes for Honda Accord: M14x1.5 and M20x1.5

Honda Accords often use two thread sizes for their oil drain plugs. These are M14x1.5 and M20x1.5. The first size, M14x1.5, is found on the oil drain bolt of most Honda Accords. This means the bolt has a diameter of 14 millimeters and a pitch, or gap between threads, of 1.5 millimeters.

Some Accords may also have an M20x1.5 size for parts like the oil filter threads where this larger bolt measures 20 millimeters across and again sports a gap of 1.5 millimeters between threads.

The importance of using the correct size for your vehicle

The right oil drain plug size matters a lot for your Honda Accord. The plug must fit just right. If it’s too big, it won’t go in. On the other hand, a small one can fall out and cause leaks.

Leaks can lead to less engine oil, which harms your car’s engine over time. Checking the size keeps your car running well and saves money on repairs. A correct-size wrench or socket helps you change the plug easily too.

Using these tools will stop the damage from happening during changes as well.

Tips for Changing Your Honda Accord’s Oil Drain Plug

When changing your Honda Accord’s oil drain plug, make sure to use the correct wrench size for easy removal and installation. Apply thread sealant if necessary to prevent leaks. Regularly check and replace the plug to maintain a tight seal and prevent oil leakage.

Using the correct wrench size

To remove the oil drain plug on your Honda Accord, make sure to use a 17mm socket and wrench. This is the proper size for most models of the Accord. When removing the drain plug, only turn the wrench about halfway to avoid damaging the plug or stripping the threads.

It’s also important to clean any oil or residue around the plug before proceeding with removing it. By using the correct wrench size and following these steps, you can safely and effectively change your Honda Accord’s oil.

Applying thread sealant if necessary

If you notice any leaks when changing your Honda Accord’s oil drain plug, it may be necessary to apply thread sealant. This can help prevent any oil from seeping out and causing further issues.

Thread sealant is a special adhesive that creates a tight and secure seal between the drain plug and the oil pan. It helps to fill in any gaps or imperfections in the threads, ensuring a leak-free connection.

By applying thread sealant when needed, you can keep your oil drain plug tightly secured and avoid potential leaks or damage to your vehicle’s engine.

Regularly checking and replacing the plug to prevent leaks

If you want to avoid oil leaks in your Honda Accord, it’s important to regularly check and replace the oil drain plug. By doing this routine inspection and replacement, you can prevent potential damage to the oil pan and ensure proper sealing of the drain plug.

Oil leaks around the drain plug can lead to serious engine problems if not addressed, so it’s crucial to take proactive measures. Regular maintenance, including checking and replacing the plug when needed, will help prevent any oil leakage from the drain plug area.

This will keep your car running smoothly and avoid reduced fuel efficiency or engine damage caused by neglected oil changes.


In conclusion, understanding the correct oil drain plug size for your Honda Accord is essential to maintain the integrity of your vehicle’s engine. By using the correct size plug and ensuring it is properly tightened, you can prevent leaks and ensure smooth oil changes in the future.

Remember to regularly check and replace the drain plug as needed to keep your Honda Accord running smoothly.
