What size is the thread on a Toyota sump plug?

The typical thread size for a Toyota sump plug is M14 x 1.5. This means the plug has a diameter of 14 millimeters and a thread pitch of 1.5 millimeters per thread. This is a common size used on many Toyota vehicles to secure the oil drain plug at the bottom of the oil pan.


Understanding Sump Plug Thread Sizes


The sump plug, also known as the oil drain plug, is a critical component on any vehicle that allows the engine oil to be drained during routine maintenance. The thread size of the sump plug is an important specification, as it needs to match the threaded hole in the oil pan to create a secure, leak-free seal.


Sump plug thread sizes are typically expressed using the metric system, with the diameter in millimeters and the thread pitch (the distance between each thread) also in millimeters. Common sump plug sizes include M12 x 1.25, M14 x 1.5, and M16 x 1.5.


Why the M14 x 1.5 Size for Toyota?


Toyota has standardized on the M14 x 1.5 thread size for the sump plug on many of its vehicle models. This size provides a secure, leak-proof connection while also being large enough to allow the oil to drain quickly during an oil change. The 1.5 mm thread pitch also helps ensure a tight fit and prevents the plug from loosening over time.



  • The M14 diameter is large enough to accommodate the oil flow from the oil pan.

  • The 1.5 mm thread pitch creates a strong, durable connection that resists loosening.

  • This size is commonly used across Toyota's lineup, simplifying parts inventory and maintenance.


Knowing the correct sump plug thread size is important when performing an oil change or other maintenance on a Toyota vehicle. Using the wrong size plug could result in leaks, damage to the oil pan, or other issues.
