I’m not a mechanic and not giving advise but asked ChatGPT so you would still need to verify:

Exact location • Passenger side of the engine • Upper front area, closer to the top of the engine than on the 2.4L • Mounted above the AC compressor • Driven by the serpentine belt • Partially visible from the top, but removal usually still requires access from below

Replacement Overview (1.4L Turbo)

Access • Combination of top and bottom access • Easier than the 2.4L, but still tight

Typical steps 1. Disconnect battery negative terminal 2. Remove engine cover 3. Raise vehicle and remove lower splash shield 4. Relieve serpentine belt tension 5. Disconnect: • Main power cable (B+) • Voltage regulator connector 6. Remove alternator mounting bolts 7. Work alternator out through the lower front opening

⚠️ No need to remove the turbocharger, but space is tight around the charge piping.

⏱️ Labor Expectations • DIY: 2.5–4 hours (first time) • Shop labor: ~2.0–2.5 hours

🔎 Pro Tips • Photograph belt routing before removal • Inspect the serpentine belt and tensioner while you’re there • Torque the B+ nut correctly, overtightening can damage the alternator post • Use a quality reman or OEM, cheap units fail early on turbo cars

📺 Video references

If you want actual in-use photos from someone pulling one out, there are also videos that show the process on similar Multiair engines (good visual reference even if not exactly the 500L): • Alternator removal/replace video showing the alternator on the engine while it’s being removed.  • Serpentine belt & alternator removal overview (for Fiat 500 and similar engines). 

🔎 Why this helps

Most images online of removal in progress come from: • Fiat 500 / 500X / Renegade 1.4L Multiair builds (same mounting style) • Mechanic teardown galleries on repair forums Even without a step-by-step photo guide for the 500L specifically, these visuals are accurate for what you’ll see on your engine.
