On the 14th-gen F-150 the starter lives low on the passenger side of the block and you reach it from underneath after dropping the lower splash shields. The 5.0L Coyote is the easiest of the bunch — two bolts and a cable nut once the shield is off. The 2.7L and 3.5L EcoBoost trucks put the starter tighter against the turbo plumbing and exhaust, so pulling the passenger front wheel and using a swivel extension turns a knuckle-busting hour into a manageable one.
The biggest mistake is buying a starter at all. A weak AGM battery or a corroded B+ cable at the starter stud gives the exact same single-click no-crank, and these trucks with auto start-stop are hard on batteries. Load-test the battery and wiggle-test the cables first. The second mistake is skipping the negative-cable disconnect: the big stud on the starter is hot all the time, and one slip with a 13 mm socket will ruin your day.

2.7L and 3.5L EcoBoost and the 5.0L V8 all use a conventional 12V starter on the lower passenger side, but the starters are not interchangeable and the mounting bolt heads are 15 mm on most builds and 13 mm on some — carry both. The 3.5L PowerBoost hybrid has no starter motor; the engine is cranked by the electric machine in the 10R80 modular hybrid transmission, so this job does not apply to it.
| Starter mounting bolts (2.7/3.5 EcoBoost, 5.0L) | verify in the service manual (typically in the 15-20 ft-lb / 20-27 Nm range for M8 and 30-40 ft-lb for M10 — confirm before tightening) |
| Starter solenoid B+ cable nut | verify in the service manual (snug, do not spin the stud) |
| Solenoid trigger wire nut | verify in the service manual |
| Negative battery terminal clamp | verify in the service manual |
| Front wheel lug nuts | 150 ft-lb (204 Nm) |
| Underbody shield / skid plate bolts | verify in the service manual (low — do not over-tighten into plastic) |
Starter location (low passenger side, accessed from below) and the 8 mm battery terminal, 13 mm B+ cable nut and 21 mm lug nuts are reliable across this generation, but the starter mounting bolt head size varies between 13 mm and 15 mm by engine and build date, so test-fit both and confirm the mounting bolt torque in the Ford workshop manual before final tightening.
Low on the passenger side of the engine block at the bellhousing, accessed from underneath after removing the lower engine splash shield/skid plate. On EcoBoost trucks, removing the passenger front wheel makes it far easier to get tools on the bolts.
No. The 3.5L PowerBoost uses the electric motor built into the 10R80 hybrid transmission to start the engine, so there is no separate 12V starter to replace. A no-crank on a PowerBoost points to the 12V battery, high-voltage battery, or hybrid control system and needs a scan tool.
Most are 15 mm, though some builds use 13 mm heads. Bring both plus a swivel extension for the upper/rear bolt, and confirm the torque figure in the Ford workshop manual rather than guessing.
No programming is required for the starter itself. Disconnecting the battery will reset the clock, radio presets, window/idle learned values, and may temporarily disable auto start-stop for a few drive cycles until the battery monitoring sensor relearns.
