On the 13th-gen F-150 the starter lives low on the passenger side of the bellhousing and comes out from underneath. Electrically it is a five-minute job — one big battery cable on a stud, one small signal wire, two bolts — but the upper bolt is blind and tucked behind the exhaust, so long extensions and a swivel matter more than muscle.
What varies is the access clutter. EcoBoost trucks have a charge-air pipe and extra heat shielding near the starter; the 5.0 is a bit more open but sits close to the exhaust manifold. The mistake people make is skipping the battery disconnect: the B+ stud is hot all the time and a slipped socket against the bellhousing will spark badly. The second mistake is condemning the starter when the real issue is a tired 12V battery on an auto start-stop truck — load test the battery first.

Starter mounting bolt heads are 13 mm on most builds and 15 mm on others regardless of engine, so carry both. EcoBoost 2.7L and 3.5L trucks usually require moving the passenger-side charge-air pipe or heat shield for clearance, which the 5.0L and 3.3L do not; the 5.0L sits closer to the exhaust manifold so let it cool fully. The starter unit itself is different part numbers between EcoBoost, 3.3/3.5 NA V6 and 5.0 V8 — order by VIN.
| Starter mounting bolts | 18-20 ft-lb (25-27 Nm) — verify in the service manual for your engine |
| Starter B+ cable nut | about 9-13 ft-lb (12-18 Nm) — verify in the service manual |
| Negative battery terminal clamp nut | about 7 ft-lb (9 Nm) — verify in the service manual |
| Front wheel lug nuts (if wheel removed) | 150 ft-lb (204 Nm) |
Starter mounting bolt heads on this generation are 13 mm or 15 mm depending on engine and build date and the B+ nut is 13 mm — have both sizes on hand and confirm torque values against the Ford workshop manual for your VIN.
Low on the passenger side of the engine where the transmission bellhousing meets the block, accessed from underneath the truck. You do not remove anything from above; a floor jack, jack stands and long extensions are what you need.
The mounting bolts are 13 mm or 15 mm depending on build, and the B+ battery cable nut on the solenoid is 13 mm. The negative battery terminal clamp is 8 mm.
Usually not the exhaust. Removing the passenger front wheel and inner fender liner gives much better arm room and is worth the ten extra minutes, especially on EcoBoost trucks.
Most often the B+ cable nut is loose or the eyelet is corroded, or the small solenoid signal wire is not fully clicked in. Also check the 12V battery — auto start-stop trucks kill batteries early and a weak battery gives the same single click.
