The oil drain plug uses a 14 mm hex socket (14 mm wrench size) for removal and installation.
For the 2013 Honda Pilot, which is equipped with the 3.5-liter V6, the drain plug is located on the bottom of the engine oil pan and typically requires a 14 mm socket to loosen and tighten. When reinstalling, it’s standard to replace the copper crush washer to ensure a proper seal. If you have a different engine variant or aftermarket components, always check the owner’s manual or the official service data for your exact vehicle.
Confirming the plug size and where it sits
To validate the correct size, you can inspect the plug directly and test-fit a socket. Use the following steps to verify and proceed safely.
Before listing the practical steps, note that verifying the size on your specific vehicle helps prevent stripping or leaks.
- Locate the oil pan drain plug at the bottom of the engine. It is typically accessible from beneath the vehicle.
- Test-fit a 14 mm socket to loosen the plug. If it slides in easily and seats snugly without wiggling, you have the correct size.
- If a 14 mm socket does not fit or feels loose, stop and re-check the manual or inspect the purge plug type—some aftermarket plugs may have different heads.
- When reinstalling, place a new copper crush washer on the drain plug and torque to the manufacturer’s specification using a torque wrench.
Concluding note: Verifying with the owner’s manual or service data is the best way to confirm, especially if you’re working with a replacement drain plug or added aftermarket hardware.
Additional maintenance tips
While you’re servicing the drain plug, consider related steps that help ensure a clean oil change and a leak-free seal. Replace the oil filter, use the recommended oil grade for the engine, and dispose of used oil responsibly at a proper collection point. Maintaining the drain plug and washer is a simple but important part of long-term engine health.
Summary
For a 2013 Honda Pilot, the oil drain plug typically requires a 14 mm hex socket. Verify by inspecting the plug directly or consulting the owner’s manual, replace the copper washer on reinstallation, and torque to the official specification with a torque wrench to prevent leaks.
