What size is the drain plug on a Honda Fit?

The oil pan drain plug on most Honda Fit models uses an M14 x 1.5 thread with a 14 mm hex head, typically requiring a 14 mm socket or wrench.


While this size covers the majority of Fit/Jazz variants with the common 1.5-liter engine, variations can occur by market, year, or engine option. Always verify against your owner's manual or a current parts diagram for your specific VIN.


Standard size for the Honda Fit oil drain plug


Key specifications you should know when performing an oil change on a typical Honda Fit are listed below:



  • Thread size: M14 x 1.5

  • Hex head size: 14 mm

  • Common applicability: fits most Fit/Jazz models with the standard 1.5L engine


These specs cover the majority of Fit models. If your vehicle uses a different engine variant or a non-OEM drain plug, confirm the exact size before proceeding.


How to confirm the exact size for your vehicle


Before you attempt a drain, use these steps to ensure you have the correct plug size for your exact car:



  1. Check the owner's manual or the official service/repair manual for your engine code and pull the drain plug specification.

  2. Inspect the existing drain plug or consult a parts diagram for your specific VIN to confirm thread size and head type.

  3. If in doubt, ask a Honda dealer or parts counter with your VIN to confirm the correct M x pitch and head size before purchasing.


In practice, most owners will use the standard M14 x 1.5 drain plug with a 14 mm head, but confirming via your manual or dealer ensures compatibility and protects the oil pan threads.


Variations by market and model year


Honda Fit models from different markets or older generations may show minor variations in drain plug size or head design. The guidance above reflects the common configuration for the typical 1.5L Fit, but if your vehicle is a specialized export variant or an unusual year, consult the exact service sheet or a dealer for the precise specification.


Summary


For most Honda Fit models, the oil pan drain plug is M14 x 1.5 with a 14 mm hex head. Always verify with your vehicle’s manual or parts diagram for your exact VIN, and when in doubt, consult a Honda dealer or qualified technician to avoid cross-threading or damage to the oil pan.
