Remy 94738 alternator for the 2010-2013 Mazda 3 4-cylinder 2.0L and other vehicles charges the battery and supplies electrical power while the engine runs.
Dim headlights, a battery warning light or a battery that keeps going flat can point to a weak alternator. Before you replace this one, rule out a worn battery, a slipping drive belt and loose or corroded battery cable ends, since each can produce similar symptoms.
This alternator is a direct-fit replacement for the 2010-2013 Mazda 3 4-cylinder 2.0L and the 2010-2013 Mazda 3 Sport 4-cylinder 2.0L.
