Detailed Description

The WAI 11453N alternator is engineered for direct replacement use in a range of Chevrolet, Buick, Cadillac, and GMC applications. It is specified as a 12-volt unit with a 150 amp amperage rating, clockwise rotation, and no decoupled or clutch pulley. The internal regulator and internal fan support consistent charging performance in vehicles that rely on stable electrical supply for accessories and onboard systems. This part number 11453N is listed for applications including Chevrolet Impala, Buick LaCrosse, and Chevrolet Equinox, among others.

WAI builds this alternator as a new unit using proprietary components and manufacturing processes to support long service life and dependable output. The Valeo family design and 150 amp rating make it a practical choice for drivers replacing a worn charging unit on GM platforms that require this specification. Part number 11453N also cross-references Monroe Shocks & Struts (e.g., 11453) for the same application.

What It Is Used For

• Low battery charging caused by alternator wear
• Dim lights or electrical instability under load
• Charging system warning lights
• Reduced output from a failing factory alternator
• Replacement on vehicles requiring a 150 amp alternator

Installation Notes and Tips

Verify the amperage rating, rotation direction, regulator type, and pulley configuration before installation. Confirm the vehicle’s charging system requirements and match the application notes, especially for 2012 Cadillac SRX builds with the listed production cutoff. Use the existing belt and electrical connections only after confirming they match the alternator specification.

Quality Assurance

WAI states that this alternator is 100% new and manufactured with proprietary components and processes to support maximum life and performance.
