Detailed Description

The WAI 44004N alternator is engineered for late-model GM trucks and SUVs that rely on stable charging output for accessories, lighting, and onboard electronics. Its 170 amp rating, clockwise rotation, and serpentine pulley setup make it a direct-match style replacement for the specified applications, including Cadillac Escalade, Chevrolet Silverado 1500, and GMC Sierra 1500 fitments. The part number 44004N identifies this configuration for buyers matching by OE-style reference or interchange data.

Because this unit is built new rather than remanufactured, it is intended for customers who want a replacement alternator with proprietary components and manufacturing processes focused on service life and consistent performance. The 44004N also aligns with DENSO 170 amp applications identified in the fitment notes.

What It Is Used For

• Charging-system warning lights caused by alternator output loss
• Battery drain from insufficient charging performance
• Electrical instability under accessory-heavy operation
• Voltage drop affecting lights, modules, or infotainment systems
• Replacement of a worn or failed OE-style alternator

Installation Notes and Tips

Verify the pulley style, amperage rating, rotation direction, and connector match before installation.
