What size is the drain plug on a 1.5 EcoBoost?
The oil drain plug for most 1.5L EcoBoost engines uses a metric M14 x 1.5 thread and a 14 mm hex head, so a 14 mm socket is typically required to remove it.
The 1.5 EcoBoost is used across a range of Ford models and years, including Focus, Fiesta, Escape, and more. Variations in oil pan design and model-year changes can affect the exact size, so it’s important to confirm the specification for your specific vehicle. This article outlines the common size and how to verify it on your car.
Common drain plug size for the 1.5 EcoBoost
Before listing the baseline dimensions, keep in mind these key details that apply to many installations of this engine.
- Thread size: M14 x 1.5 (metric, common on this engine family)
- Socket size: 14 mm hex (requires a 14 mm wrench or socket)
- Sealing features: some plugs use a copper or other sealing washer; replace if your plug uses one

In most cases, you’ll encounter an M14 x 1.5 drain plug with a 14 mm socket, but always confirm against your specific vehicle’s manual or by inspecting the existing plug before purchasing a replacement.
How to verify the exact size for your vehicle
If you’re not certain of your car’s drain plug size, use these steps to verify before proceeding with maintenance tools or replacements.
- Check the vehicle’s owner’s manual or the official service manual for the correct drain plug specification for your model year and engine.
- Inspect the current drain plug on your engine for any size markings or part numbers that could indicate the correct size.
- Measure the thread diameter with calipers or a thread gauge; an apparent diameter near 14 mm with a 1.5 mm pitch indicates M14 x 1.5.
- Cross-check the VIN with Ford’s parts catalog or a dealer to confirm the exact plug size and part number for your car.
- If in doubt, visit a Ford dealer or a trusted mechanic to confirm the correct plug size and torque specification for your engine.
Following these steps helps ensure you select the correct drain plug size and avoid cross-threading or leaks during an oil change.
