The oil drain plug uses a 14 mm hex-head bolt with M14 x 1.5 thread. A 14 mm socket or wrench is the correct tool to remove or install it.
For the 2014 Honda Fit, the standard engine oil drain plug is a metric fastener that threads into the oil pan with an accompanying crush washer to seal the joint. The typical OEM plug has a 14 mm hex head and M14 x 1.5 threading. Some regional variations or aftermarket plugs may differ, but the 14 mm/ M14 x 1.5 specification covers the vast majority of models sold in many markets. Always verify against your VIN-specific service manual if you’re unsure.
Plug size details
Thread and head specifications
The drain plug’s thread is M14 x 1.5, designed to seal with a crush washer. The hex-head size you’ll typically encounter is 14 mm, which corresponds to a 14 mm socket or wrench. In most cases, OEM Hondas use a 14 mm hex head; some aftermarket variants may use alternate interfaces, but the factory plug for the 2014 Fit is the 14 mm hex, M14 x 1.5.
Tools and preparation
Before you start, gather the tools and supplies you’ll need to remove and replace the drain plug and the engine oil.
- 14 mm socket or 14 mm open-end wrench
- Ratchet or breaker bar for leverage
- Oil drain pan
- New crush washer (or the OEM replacement gasket if applicable)
- Fresh engine oil to top off after draining
- Gloves and rags for cleanup
Using the right tools helps ensure the plug is removed without rounding the head, and the new crush washer forms a proper seal to prevent leaks.
Steps to remove and reinstall the drain plug
Follow these steps to safely drain the engine oil and reinstall the drain plug with a proper seal.
- Warm up the engine, then park on a level surface and engage the parking brake. Place the drain pan underneath the oil pan drain plug.
- Loosen the drain plug with a 14 mm socket using a counterclockwise motion; remove it once it’s free and allow the oil to drain completely.
- Inspect and clean the drain plug. If your OEM plug uses a crush washer, replace it with a new one before reinstalling the plug.
- Reinstall the drain plug by hand to avoid cross-threading, then snug it with a 14 mm socket. If you have a torque wrench, tighten to the manufacturer’s specified torque.
- Refill the engine with the correct amount and grade of oil as per the owner’s manual, then check the oil level with the dipstick and add more if needed until it reads at the full mark.
- Run the engine briefly, check for leaks around the drain plug, stop the engine, and recheck the oil level once it’s cooled.
Working carefully lowers the risk of leaks and ensures the engine remains properly lubricated after the service.
Regional variations and tips
