What size is the oil drain plug on a 2013 Ford Cmax?

The oil drain plug for the 2013 Ford C-Max uses a 14 mm hex head with M14 x 1.5 thread. This size is standard for that model year’s 2.0-liter engine variants, including both the Hybrid and Energi plug‑in versions. Always verify with your owner’s manual or the service manual if you have a different engine configuration or market specification.


Plug size and compatibility


Key dimensions and compatibility for the drain plug are summarized below.



  • Head size: 14 mm hex

  • Thread size: M14 x 1.5

  • Common tool: 14 mm socket or wrench

  • Vehicle variants: Applies to 2013 C-Max with 2.0-liter engine (Hybrid and Energi plug-in)


With these specifications in mind, you can select the correct tool and replacement parts to complete an oil change without risk of stripping the plug or leaving a leak. Always inspect the plug and nearby sealing surface for wear and replace the washer or plug if signs of damage are present.


Practical steps for verification and replacement


Before performing a drain plug removal or replacement, it helps to confirm the exact spec on your individual vehicle and follow standard oil-change procedures.



  1. Locate the oil pan drain plug on your C-Max and verify its hex head size looks like 14 mm.

  2. Use a 14 mm socket or wrench to loosen and remove the plug carefully, supporting the oil pan area to catch drained oil.

  3. Inspect the plug threads and any sealing washer; replace the plug or washer if there is any galling, cross-threading, or damage.

  4. Reinstall the plug with a clean sealing surface and tighten to the manufacturer’s recommended torque from the service manual (avoid over-tightening).


These steps help ensure a clean oil change with a properly sealed drain plug, minimizing the possibility of leaks or damage to the oil pan.


Related considerations


If you own a different market specification or a non-standard engine variant, sizes may differ. Always cross-check with Ford’s official documentation or consult a certified mechanic if you’re unsure about the exact drain plug dimensions for your vehicle.
