What size is the oil bolt on a 2016 Honda Civic?
The drain plug on a 2016 Honda Civic uses an M14 x 1.5 thread with a 14mm hex head for removal in most US-market models. Use a 14mm socket to remove it, and torque it to roughly 20–25 ft-lbs (about 27–34 Nm) when reinstalling. Always confirm with your owner's manual or service manual for your exact engine variant and washer needs.
Overview of the drain plug specifications
On the 2016 Civic, both common engine options (the naturally aspirated 2.0L and the 1.5L turbo) typically share the same drain plug thread size. The plug is designed to work with a crush washer, and using the correct torque helps prevent leaks and ensures a proper seal. If you’re unsure of your exact variant, consult the maintenance section of your manual or a Honda service bulletin for your VIN.
Thread size and head size
The standard oil drain plug is M14 x 1.5 in thread size, which means the hole that accepts the plug has a 14 millimeter diameter with 1.5 millimeters of thread pitch per turn. The corresponding removal head is typically a 14mm hex, which is the common socket size used to loosen and tighten the plug on most Civic models from this era. In some cases or with aftermarket parts, you may encounter a plug with a different head type, so verify if you’re using an OEM-style plug.
Tools you might need for the job include a 14mm socket or wrench, a torque wrench for precise reinstall torque, an oil drain pan, a replacement crush washer, and clean lint-free rags for cleanup. It’s also wise to have fresh motor oil, a funnel, and gloves to protect your hands from hot oil.
Below are practical steps and considerations that apply broadly to maintenance and replacement of the drain plug’s washer and seal during an oil change.
Before performing maintenance, the following list details the basic preparation and tools commonly used across Civic oil changes.
Tools and supplies commonly needed for removing and reinstalling the drain plug
- 14mm socket or 14mm wrench
- Oil drain pan
- Replacement drain plug crush washer (and/or O-ring if specified)
- Torque wrench (optional but recommended)
- Shop rag or paper towels and motor oil for cleanup
Having the right tools helps ensure a clean, leak-free reinstall and makes the job safer and faster.
Step-by-step procedure for removing and reinstalling the drain plug
To guide a typical oil change, use these steps as a general reference. Always refer to the official manual for your exact vehicle and oil specification.
- Warm up the engine briefly to allow the oil to drain smoothly, then park on a level surface and engage the parking brake.
- Place the oil drain pan beneath the oil pan drain plug.
- Use a 14mm socket to loosen and remove the drain plug. Allow the oil to drain completely.
- Inspect the drain plug and crush washer for wear or damage; replace the washer if required.
- Reconnect the drain plug by hand, then snug it with a 14mm wrench. If you’re using a torque wrench, tighten to approximately 20–25 ft-lbs (27–34 Nm), and avoid over-tightening.
- Refill with the recommended grade and quantity of oil for your Civic, then check for any leaks after a brief idle and recheck the oil level on the dipstick.
These steps cover the standard procedure for most 2016 Civics. If your model has a different drain-plug configuration or you’re using aftermarket parts, double-check the torque specification and washer type recommended by Honda for your VIN.
Engine variants and potential differences
While the 2016 Honda Civic lineup includes both a 2.0-liter naturally aspirated engine and the 1.5-liter turbocharged engine, the drain plug thread size is commonly listed as M14 x 1.5 across these variants. Some regional or late-model variations might differ slightly in washer requirements or torque specs, so always verify with the official service information for your specific vehicle if you suspect a discrepancy.
Where to find official specs
Your best source for the exact torque, washer type, and any variant-specific notes is the official Honda service information for your VIN. The owner’s manual includes general oil-change guidelines, while the service manual provides precise specifications for drain plug torque and any required washers or thread sealants.
Summary
For a 2016 Honda Civic, the typical oil drain plug uses an M14 x 1.5 thread with a 14mm head. Reinstall the plug to about 20–25 ft-lbs (27–34 Nm) and replace the crush washer as needed. Always confirm exact specifications for your VIN and engine variant in the owner’s manual or Honda service documentation, and use the proper tools to ensure a clean, leak-free oil change.
What size is a Honda oil drain plug?
The most common oil drain plug size for many Honda vehicles is M14-1.5, which requires a 17mm socket to turn. However, some older or different models may use a different size, such as 12mm. Always confirm the correct size for your specific Honda model before purchasing a replacement part.
Common Honda oil drain plug sizes
- Thread: M14-1.5
- Socket size: 17mm
- Alternative/Older models: 12mm
Important considerations
- Always confirm your vehicle's specific size: While M14-1.5 is common, it's best to check the owner's manual or the existing plug to ensure you have the correct size.
- Replace the washer: It is recommended to replace the crush washer with every oil change to ensure a good seal and prevent leaks. Some plugs come with a new washer, but it's a good idea to have one on hand.

What size socket for Honda Civic oil plug?
A 17mm socket is the correct size for a Honda Civic's oil drain plug. You may also need a Phillips screwdriver for the splash guard and a 3/8-inch socket for some models, though the 17mm socket for the drain plug itself is the most critical tool.
Tools and parts needed
- 17mm socket or wrench
- New drain plug crush washer
- Oil filter
- Oil filter wrench (if needed)
- Phillips head screwdriver (for splash guard)
- Oil drain pan
- Funnel
- Rags or towels
Before you start
- Locate the oil drain plug, which is on the bottom of the oil pan.
- Place an oil drain pan underneath the plug to catch the used oil.
- If your car has a splash guard, remove it first using a Phillips head screwdriver.
Removing the drain plug
- Fit the 17mm socket onto the drain plug and turn it counterclockwise to loosen it.
- Be careful not to strip the plug, especially if it's very tight. A six-point socket is recommended over a twelve-point socket for a better grip.
After you finish
- When re-installing, use a new crush washer and tighten the plug to the manufacturer's recommended torque (around 30 ft-lbs30 ft-lbs30 ft-lbs for many Honda models).
- Be sure to also replace the oil filter after applying a thin layer of new oil to its rubber gasket.
