What size is the oil drain plug on a Toyota Corolla?

The oil drain plug size on a Toyota Corolla is typically 17mm. This is the standard size used for the oil drain plug on most Toyota Corolla models, allowing for easy oil changes and maintenance.


Understanding the Oil Drain Plug


The oil drain plug is a crucial component of a vehicle's oil change system. It is located at the bottom of the oil pan and is responsible for allowing the old oil to be drained from the engine during an oil change. The size of the oil drain plug is an important factor to consider when performing this routine maintenance task, as using the wrong size plug can lead to leaks or damage to the oil pan.

It's important to note that the oil drain plug size may vary slightly depending on the specific model year and engine configuration of your Toyota Corolla. Always refer to your owner's manual or consult with a professional mechanic to ensure you have the correct replacement part.


Changing the Oil Drain Plug


When changing the oil in your Toyota Corolla, it's essential to use the correct size oil drain plug. Attempting to use a plug that is too small or too large can result in leaks, stripped threads, or other issues that could lead to more extensive and costly repairs.



  • Drain the oil: Locate the oil drain plug, typically at the bottom of the oil pan, and use the appropriate size wrench or socket to loosen and remove it.

  • Replace the plug: Once the oil has been drained, clean the threads on the oil pan and apply a small amount of thread sealant or lubricant to the new 17mm oil drain plug.

  • Tighten the plug: Carefully thread the new 17mm oil drain plug into the oil pan and tighten it securely using the appropriate wrench or socket.

  • Check for leaks: After replacing the oil and the drain plug, inspect the area for any signs of leaks and address any issues immediately.


Following these steps and using the correct 17mm oil drain plug size will help ensure a successful oil change and maintain the overall health of your Toyota Corolla's engine.
