Alright, here's how you remove the alternator on a 2006 Ford Focus LS with the 2.0L Duratec HE:
- Disconnect the battery — Always start with the negative terminal. You don’t want to short the alternator.
- Relieve the serpentine belt tension — Use a wrench or socket on the belt tensioner and slip the belt off the alternator pulley.
- Unplug the alternator wiring
- One main power cable (usually held by a nut)
- One small plug connector
- Make sure the battery is already disconnected before doing this.
- Remove the alternator mounting bolts — There are usually 2 or 3 bolts holding it to the bracket. Support the alternator as you remove the last bolt — it’s heavier than it looks.
- Work the alternator out — This is the fiddly part. You usually have to wiggle it out from the top or bottom, sometimes rotating it a bit to clear hoses and brackets. No need to remove the engine, but patience helps.
- Install is reverse of removal — Bolt it back in, reconnect wiring, refit the belt, then reconnect the battery.
A couple of tips from experience:
- Take a photo of the belt routing before removing it
- Don’t overtighten the main power cable — snug is enough
- Double-check the belt is seated properly on all pulleys before starting
If you want the exact bolt locations, torque specs, and the clean step-by-step, this 2006 Ford Focus manual covers the alternator removal and installation for the 2.0L Duratec HE I4 in the LS model. If you're doing this on your own for the first time, it's the perfect guide to get!
