The oil drain plug on the 2016 Honda CR-V requires a 17 mm socket for removal.
This article explains the correct size, how to verify it, and practical steps for a safe oil-change procedure on the 2016 CR-V, including tips for variations and accessories you might need.
Confirming the size and using the socket
The 2.4-liter inline-four engine used in most 2016 CR-Vs accepts a 17 mm socket for the drain plug. Using the correct size helps prevent rounding the bolt and ensures a proper seal when the plug is reinstalled.
When the plug or head looks worn
If the drain plug head is damaged or you’re dealing with an aftermarket plug, measure across the flats or consult the owner's manual to confirm the proper tool. Variations can exist by market or engine variant, so verify before forcing a turn.
To perform the drain-and-fill safely, follow standard oil-change procedures and ensure the vehicle is on level ground with the engine cool before starting.
Tools and supplies you'll need
Having the right tools on hand makes the oil change quicker and reduces the risk of damage to the drain plug.
- 17 mm socket and ratchet (or breaker bar for extra leverage)
- Oil drain pan
- New copper (crush) washer for the drain plug
- New engine oil and a filter as needed
- Funnel, gloves, rags
- Jack stands or ramps and wheel chocks
- Torque wrench (optional but recommended to match factory specs)
With these items ready, you can perform the oil change cleanly and safely, reducing the risk of leaks or overtightening the drain plug.
Notes on installation and torque
When reinstalling the drain plug, replace the copper crush washer and tighten to the vehicle manufacturer's specification using a torque wrench. If you do not have the exact torque figure handy, refer to the owner's manual or a service manual for the precise value. Avoid overtightening, which can strip threads or damage the oil pan.
Variations and other considerations
If you own a different market version of the CR-V or a variant with a different engine, the plug size could differ. Always verify by checking the specific owner's manual or measuring the plug head directly before purchasing tools.
Summary
For a 2016 Honda CR-V, the oil drain plug requires a 17 mm socket. Gather the listed tools, replace the crush washer, and torque the plug to the specified value per the manual. This ensures a proper seal and helps prevent leaks during oil changes.
