Market analysis

The Cadillac CT5 average ($133) runs 15% above its median ($116), indicating a tail of high-priced listings — likely low-mileage or remanufactured units pulling the average up.
Our guide covers 8 model years for the Ford F250 (2015–2024) but only 6 for the Cadillac CT5 (2020–2025), so the Ford F250 data reflects a broader range of generations.
The Ford F250 alternator is interchangeable across 16 model years versus just 9 for the Cadillac CT5 — that wider compatibility window means more donor vehicles in salvage yards and tends to push prices lower.
At Grade B (good) condition, the Cadillac CT5 is 54% cheaper ($75 vs $162) — the gap widens compared to the overall median difference.
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).
