The most common oil drain plug on Honda Accord engines is M14 x 1.5 with a 17 mm socket/head for removal and installation. However, exact size can vary by year, engine type, and market—so you should verify the specification for your specific model.
Across the Accord’s generations, different engines (4-cylinder, V6, turbo, hybrids) and regional variations have employed different plugs and washers. To prevent leaks or damage, consult the owner's manual, a reliable parts diagram, or your dealer for the correct spec for your VIN.
Common starting point and how to confirm
Use this as a quick reference and starting point. It captures the typical configuration found on many Accord models, but variations do exist.
- Thread size: M14 x 1.5 is the standard for many Honda Accords; this determines the bolt’s diameter and thread pitch.
- Head/socket size: A 17 mm wrench or socket is commonly used to remove and install the drain plug; some variants may use a different head style.
- Crush washer: Honda typically uses a copper or other crush washer with the drain plug; replace it at every oil change.
Bottom line: begin with M14 x 1.5 and a 17 mm tool as your working assumption, but always verify for your exact year and engine.
How to verify for your exact car
To be certain you have the correct size for your Accord, follow these steps:
- Check the owner's manual or service manual for your year and engine; the oil change section should specify the drain plug size and torque.
- Inspect the drain plug on the vehicle or the OEM replacement part; measure the thread diameter and count the pitch, or compare to a known reference.
- Look up the OEM part number for your VIN in the Honda parts catalog or ask a dealer to confirm the correct drain plug and washer part number.
Verifying through official sources helps ensure a proper fit and prevents cross-threading or leaks.
Related maintenance notes
Beyond size, keep these details in mind during oil service:
- Torque: Use the torque specification for your engine; typical ranges are approximately 14–22 ft-lbs, but consult your manual for the exact figure.
- Washer: Replace the crush washer with each oil change.
- Sealing: Do not apply thread sealant; rely on the washer and proper torque for a seal.
Following these best practices helps maintain a reliable oil seal and engine longevity.
Summary
For most Honda Accord models, the oil drain plug is M14 x 1.5 with a 17 mm head, but there are variations by year and engine. Always confirm the exact size for your car using the owner's manual or dealer resources, and replace the crush washer during every oil change.
