How does this alternator match my vehicle’s original part?

This SCITOO alternator is manufactured to meet OEM dimensions and mounting points so it installs like the factory unit. It maps to multiple OE numbers used across Scion and Toyota models, reducing fitment uncertainty and simplifying replacement.

• Exact OE cross-references: 11402N, 11402, 1042102270, 1042102340, 1042102341, 1042108431
• Mounting points measured to factory tolerances for bolt alignment
• Compatible pulley groove (SD6) and clockwise rotation
• Designed to work with existing wiring and connectors

What electrical and mechanical specs should I expect?

This alternator delivers 12V at up to 100A and includes an internal voltage regulator and internal cooling fan. Those specs provide stable charging for the battery and onboard electronics under typical driving loads.

• Voltage: 12V; Amperage: 100A for steady output
• Rotation: CW (clockwise) to match engine orientation
• Regulator: Internal (IR) for simplified installation
• Cooling: Internal fan (IF) and SD6 pulley groove class

How durable and reliable is the SCITOO alternator?

SCITOO uses precision CNC-machined castings and subjects bearings and assemblies to rigorous testing to ensure durability. The unit is new, fully tested to OE bearing standards, and cycled to verify long-term performance under typical operating conditions.

• 100% bearing testing to OE-level specifications
• Accelerated cycling tests to confirm durability
• Precision-machined components for consistent fit and vibration resistance
• Backed by a 24-month unlimited-mileage warranty on build quality

How easy is installation and what should I watch for?

Installation is straightforward for anyone familiar with basic automotive electrical work: disconnect the battery, remove the old alternator, fit the SCITOO unit, and set belt tension correctly. Proper belt tension is important—too loose reduces charging, too tight can damage bearings.

• Disconnect negative battery terminal before starting
• Align mounting holes and tighten fasteners to factory torque
• Adjust drive belt tension to manufacturer specifications
• Reconnect wiring harness and test charging system after installation
