Before you buy
Have the battery and alternator tested before buying; a bad battery is often mistaken for a bad alternator. Remanufactured units are common.
Confirm the part fits your exact 2010 Ford Focus by checking your VIN, engine size and trim with the seller. The Focus was sold with different options across the 2010 model year, and a part that fits one build may not fit another.
