Bosch Alternator P/N:AL0805X
Bosch AL4304N alternator for the 1999-2005 Subaru Forester H4 2.5L and other vehicles charges the battery and powers the electrical system while the engine runs. This new Bosch alternator replaces one that has stopped keeping the battery topped up.
A battery warning light, headlights that dim or a battery that keeps going flat can point to the charging system. Before you replace the alternator, look over the drive belt for cracks, glazing or fraying, and the battery terminals for corrosion or loose clamps, with the engine off, since a worn belt or a poor battery connection can mimic a weak alternator.
This alternator is listed for a wide range of Subaru models, led by the 1999-2005 Subaru Forester H4 2.5L. It is also an alternator for the 2000-2004 Subaru Outback H4 2.5L and for the 1999-2001 Subaru Impreza H4 2.2L or 2.5L, and each of those takes one. The unit is designed to be identical in fit and performance to the original equipment part. If your car is not named here, look it up in the "Vehicles it fits" section, where the other Subaru years and engines are listed.
