WAI 11037N Alternator

Alternator for Cadillac CTS

This WAI alternator, part number 11037N, is a 100% new replacement built for charging-system performance. It is engineered to deliver the amperage needed for modern electrical loads while using proprietary components and processes for long service life.

• 150-amp output for dependable charging performance.
• Internal regulator for integrated voltage control.
• Internal fan design for compact alternator construction.
• 6-groove pulley with serpentine belt drive.
• Clockwise rotation with a decoupled pulley not used.

Detailed Product Information

Built on the DENSO family design, this alternator is specified with a 12-volt electrical system, internal regulation, and a clockwise rotation pattern. The 6-groove serpentine pulley and internal fan configuration support direct charging-system replacement needs on the Cadillac CTS. If you are replacing a worn charging unit on a 2004-2007 Cadillac CTS, part number 11037N provides the electrical output and configuration details needed for a proper match. This part cross-references BBB Industries 11037 for the same application.

What It Helps Address

• Low battery charging caused by a weak alternator.
• Dim lights or electrical instability under load.
• Charging-system warning lights from alternator failure.
• Reduced output from worn internal components.
• Fitment issues when replacing the original alternator on a Cadillac CTS.

Installation Notes

Verify pulley groove count, belt type, rotation direction, amperage rating, and regulator style before installation. Confirm the vehicle uses a serpentine belt drive and matches the 12-volt, internal-regulator configuration. Professional installation is recommended for charging-system diagnosis and final verification.

Quality Assurance

WAI states that this alternator is 100% new rather than remanufactured, and it is produced with proprietary components and processes intended to support long-term performance.
