Product Details

Bosch Premium Alternators are remanufactured, built, and tested to deliver consistent performance and reliability in everyday driving conditions. The AL3315X uses a 6S pulley type, a 57 mm outside pulley diameter, and plug type 917 with rear-view plug clocking at 6 o’clock. This part number, AL3315X, is a direct replacement option for vehicles that require the specified 130 amp alternator configuration.

Compatible With 2004-2007 Toyota Highlander, 2004-2006 Toyota Sienna, and 2005-2006 Lexus RX330 applications. For 2004 Lexus RX330, verify whether the vehicle is Japan built or non-Japan built, since fitment notes differ by build origin. This part cross-references 270600A130 and 2706020280 for the same application.

Common Charging System Issues

• Battery warning light caused by alternator output loss
• Dim headlights or unstable electrical performance
• Battery not maintaining charge during normal driving
• Charging system noise related to alternator wear
• Voltage irregularities affecting vehicle electronics

Installation Notes

Confirm the vehicle’s alternator amperage rating, plug type, pulley configuration, and rotation direction before installation. Match the rear plug clocking and mounting ear orientation to the original unit. On 2004 Lexus RX330 applications, check build origin carefully to select the correct fitment. After installation, inspect belt condition, belt alignment, and charging voltage at the battery.
