The oil drain plug on a 2010 Honda Civic is typically removed and installed with a 17 mm socket, and the threads are usually M14 x 1.5. Always confirm these sizes against your specific engine variant and service data.
Across the 2010 Civic lineup, which includes the popular 1.8-liter models and the 2.0-liter variants in some markets, drain plug sizing is generally consistent. However, variations can occur by market or trim, and some service manuals may specify slightly different washers or related details. For precise work, consult the owner’s manual or the official service data for your exact vehicle identification number (VIN) and engine code.
Common drain plug specifications
The following specifications cover the most common configurations for the 2010 Civic. Use these as a guide and verify with the exact manual for your car if you’re unsure.
- Head/hex size: 17 mm socket or wrench
