Our guide covers 11 model years for the Jeep Grand Cherokee (2015–2025) but only 9 for the BMW 330i (2017–2025), so the Jeep Grand Cherokee data reflects a broader range of generations.

Buyer's checklist
What to check before buying a used alternator
- Match the amperage rating to your vehicle's spec — a lower-amp alternator will undercharge, especially with aftermarket electronics.
- Spin the pulley by hand: it should rotate smoothly with no grinding or wobble.
- Check the connector plug type. Some models switched connector styles mid-generation.
- Ask about output testing — a good yard will bench-test and confirm the unit charges at the correct voltage (13.5–14.5V).
