Remy 20479 alternator for the 1987-1989 Chevrolet Cavalier V6 2.8L, the 1990-1994 Cavalier V6 3.1L and other vehicles charges the battery and powers the electrical system while the engine runs. This Remy alternator is remanufactured.
A battery warning light, dim headlights or a battery that keeps going flat can point to a charging problem. A weak battery or a slipping drive belt can produce similar trouble, so these signs alone do not prove the alternator is the problem.
This is a direct-fit replacement for the 1987-1989 Chevrolet Cavalier V6 2.8L and the 1990-1994 Cavalier V6 3.1L. It also fits the 1991-1994 Pontiac Sunbird V6 3.1L, the 1987-1989 Chevrolet Beretta V6 2.8L and the 1990-1993 Beretta V6 3.1L. Many other vehicles take it too, so open the "Vehicles it fits" section to check your exact model and engine.
