How many amps is the alternator on a 2017 Ford Explorer?
The stock alternator on most 2017 Ford Explorers is rated at 150 amps, with some high‑load configurations using a higher-output unit. The exact amperage depends on the engine and equipment installed in your vehicle.
Engine options and typical alternator sizes
The 2017 Explorer offered multiple powertrains, and while the vast majority used the same basic electrical system, certain setups could push for higher output to support accessories and towing gear.
3.5L Ti-VCT V6
Typically around 150 amps. This engine is one of the most common configurations for the 2017 Explorer and generally uses a standard 150‑amp alternator.
2.3L EcoBoost
Typically around 150 amps as well, though some high‑load builds or optional equipment could push toward a higher output in limited cases.
Note: Exact spec can vary by production year, trim level, and optional equipment. For precise confirmation, check your vehicle’s VIN-based parts data or the alternator label itself.
How to verify the exact amperage for your vehicle
To confirm the exact alternator amperage on your specific 2017 Explorer, use these steps. They help ensure you’re looking at the correct specification for your build.
- Inspect the alternator label: look for a stamped or sticker‑mounted rating such as "Output: 150A" or "180A."
- Check the owner's manual or the service information for your exact VIN, which can specify the OEM alternator size.
- Use Ford’s official parts catalog or contact a dealer with your VIN to retrieve the original spec for that vehicle.
Confirming the exact amperage is important for diagnosing electrical issues and for aftermarket accessory installations that may draw additional current.
Why amperage matters and common symptoms of a failing alternator
A properly sized alternator keeps the battery charged and powers electrical systems like lights, infotainment, and charging ports. If the alternator isn’t delivering the expected current, you may notice warnings or performance issues.
- Dlickering or dimming headlights and interior lights
- Battery warning light on the instrument cluster
- Electrical components (radio, climate control, USB ports) behaving erratically
- Unusual noises from the engine bay or an unexpected battery discharge
If you experience these symptoms, have the alternator tested and, if needed, replaced with a unit matching your vehicle’s original spec to avoid overloading the electrical system.
Summary
For most 2017 Ford Explorers, the standard alternator is a 150‑amp unit, regardless of whether you have the 3.5L V6 or the 2.3L EcoBoost. A small subset of models with higher electrical demands may use a higher‑output alternator, but the exact amperage depends on the specific build. Always verify with your VIN and the alternator label to ensure you have the correct specification for maintenance or upgrades.
