WAI 13409N Alternator

Overview

This WAI alternator, part number 13409N, is a 100% new replacement built to deliver the amperage needed for modern electrical loads. It is engineered for direct replacement use on select Toyota applications and includes an internal regulator, internal fan, and pulley configuration matched to the application.

Key Features

• 70-amp output for stable charging performance.
• 100% new construction, not remanufactured.
• Internal regulator and internal fan design.
• Clockwise rotation with a V-belt pulley.
• DENSO family design with pulley included.

Detailed Description

The WAI 13409N alternator is built for 1993-1995 Toyota 4Runner and 1993-1995 Toyota Pickup applications. As a 100% new unit, it uses proprietary components and manufacturing processes intended to support long service life and consistent electrical output. The 70-amp rating, internal regulation, and clockwise rotation make it a practical replacement for charging-system service on these Toyota models. This part number 13409N is also cross-referenced to Carlson 13409 for the same application.

For buyers searching for a Toyota 4Runner alternator or Toyota Pickup alternator, this unit provides the specified DENSO family layout with a single-groove V-belt pulley and decoupled/clutch pulley not used. The WAI 13409N is suited to restoring charging performance when the original alternator is worn, noisy, or no longer maintaining proper system voltage.

What It Is Used For

• Restoring battery charging output after alternator wear.
• Correcting low-voltage or charging warning conditions.
• Replacing a noisy or failing alternator assembly.
• Maintaining electrical supply for lights, ignition, and accessories.

Installation Notes and Tips

Verify pulley style, belt type, rotation direction, and connector match before installation. Confirm fitment for 1993-1995 Toyota 4Runner and 1993-1995 Toyota Pickup, and compare the original unit to the 13409N before removal. Because this alternator uses an internal regulator and included pulley, it should be matched to the vehicle’s charging-system configuration during installation.

Quality Assurance

WAI states that this alternator is manufactured as a new unit rather than remanufactured, using proprietary components and processes to support service life and performance.
