Alternators

The mechanical energy created by the crankshaft is converted into electrical energy through the alternator. The alternator in your vehicle then uses this electrical energy to power your battery and keep it running as you drive. While the battery is often blamed for electrical failure, the alternator is just as likely to be at fault. If your battery is failing to hold a charge, it may be time to shop for replacement alternator parts. Discover our wide variety of OEM-quality Subaru alternator parts, including pulleys and brackets.
