Which alternator a 2016–2021 Civic takes

Alternators differ by engine, by output rating, and on stop-start cars by whether the charging system is managed by the battery sensor. The 2016–2021 Honda Civic came with several powertrains, among them 1.5L I4 CVT FWD, 2.0L I4 CVT FWD and 2.0L I4 Manual FWD. That is why we ask for the VIN, or the year, engine and trim, and confirm the part against it before you pay rather than after it arrives.
