Detailed Description

Dayco PB1509N is a replacement engine harmonic balancer engineered for vehicles that use a 6-groove serpentine accessory drive. The neutral balance configuration and cast iron outer ring support crankshaft vibration control while maintaining OE-style dimensions for service replacement. This part number, PB1509N, is listed for applications including Buick Enclave, Chevrolet Traverse, Chevrolet Impala, Cadillac XTS, GMC Acadia, and other GM platforms across the 2007-2024 model years.

Dayco’s Premium OEM Replacement Balancer line focuses on direct-fit service parts for engine repair work where correct crank bore, pulley groove count, and overall diameter matter. This balancer cross-references Dorman 594-420 for the same application.

What It Helps Address

• Crankshaft vibration from a worn or separated harmonic balancer
• Belt tracking issues related to pulley wear or imbalance
• Accessory drive noise caused by a deteriorated balancer assembly
• Service replacement needs on GM and Saab engines with a 6-groove serpentine setup
• Fitment corrections when replacing an OE-style balancer on Buick Enclave, Chevrolet Traverse, or GMC Acadia models

Installation Notes and Tips

Verify crank bore, nose diameter, pulley groove count, and balance type before installation. This PB1509N harmonic balancer does not include hardware, installation instructions, timing marks, or a woodruff key, so reuse or source the required engine-specific components as needed. Confirm whether your application requires a keyed or non-keyed configuration, especially on 2007-2011 and other noted keyway applications.
