The oil drain plug on a 2017 Ford Fusion uses M14 x 1.5 threads and a 14mm hex head for removal and installation.
Common drain plug size for 2017 Fusion engines
To help you identify the exact size for your engine, here are the main Fusion engines and their standard drain plug specs:
- 2.5L I‑4 engine: M14 x 1.5 threads with a 14mm hex head.
- 1.5L EcoBoost engine: M14 x 1.5 threads with a 14mm hex head.
- 2.0L EcoBoost engine: M14 x 1.5 threads with a 14mm hex head.
Note: These dimensions cover the typical installations in many markets and model years. Always confirm for your specific vehicle using the VIN, workshop manual, or Ford parts lookup, especially if aftermarket parts were used or the vehicle has had modifications.
How to verify for your vehicle
If you want to be certain of the plug size for your exact car, use these checks and resources.
Check your owner's manual or Ford service data
Your manual or a Ford service sheet for your trim and engine code will list the correct drain plug size and torque specifications.
Inspect the plug in person
During maintenance, inspect the actual drain plug head. If a 14mm socket fits, you’re dealing with the standard size. If the head appears different, measure or consult the dealer to avoid cross-threading or damage.
For practical oil changes, ensure you use the correct crush washer and torque the plug to the manufacturer’s specification to prevent leaks.
Notes and tips
Here are precautionary tips to follow when changing oil in a 2017 Fusion.
- Always replace the drain plug crush washer with a new one to ensure a proper seal.
- Use the recommended oil grade and viscosity for your engine as listed in the owner's manual.
- Dispose of used oil responsibly and recycle the drain plug if it has a magnet and collects metal shavings.
Following these steps helps prevent leaks and maintain engine health after an oil change.
Summary
In most 2017 Ford Fusion models, the oil drain plug uses M14 x 1.5 threads and a 14mm hex head. This applies across the common engines in the lineup (2.5L I‑4, 1.5L EcoBoost, 2.0L EcoBoost), but always verify with your specific VIN and service data or the dealer to confirm, especially if aftermarket parts or changes were made.
