The oil pan drain plug on most Honda CR-V models uses a 14 mm hex head, which fits a 14 mm socket (roughly 9/16 inch). This is the typical size you’ll encounter for the engine oil drain. Always confirm with your specific year and engine in the owner’s manual if you’re unsure.
Engine oil drain plug: typical size
In the vast majority of Honda CR-Vs, the engine oil pan drain plug is 14 mm. This means a 14 mm socket or a 9/16 inch wrench is usually appropriate. If you’re changing the oil, using the correct size helps prevent rounding the head or stripping the plug. For accuracy on your exact model, consult the owner’s manual or service guide.
To quickly verify the size on your CR-V, follow these practical steps:
- Locate the oil pan drain plug on the bottom of the engine oil pan and inspect the head shape and size.
- Start with a 14 mm socket; this is the most common size for CR-V engine oil drains.
- If the 14 mm socket doesn’t fit properly or the head appears different, do not force it. Check the manual or look up your exact year and engine code to confirm.
- When replacing the drain plug, use a new gasket or washer as recommended by Honda and avoid overtightening.
- For torque specification, refer to the owner's manual or service guide to ensure the plug is tightened to the correct value.
These steps help confirm you’re using the correct socket size and protect the drain plug from damage during an oil change.
Other drain points on the CR-V
Besides the engine oil drain, some CR-V generations have other drain points (such as for the transmission or cooling system) that may use different socket sizes. These are not the engine oil drain plug, and you should verify each one separately in the service manual or with the dealer to avoid using the wrong tool.
Summary
For most Honda CR-V models, the engine oil pan drain plug uses a 14 mm hex head, corresponding to a 14 mm socket (about 9/16 inch). Always verify with your specific model year and engine in the owner’s manual or a trusted service guide, and use the correct torque and new gasket when performing an oil change.
