Product Description:
Hawks Motorsports is pleased to offer our clients the following.
The Dorman 34209 A/C Compressor Bypass Pulley is designed for select 1993-2002 Buick, Cadillac, Chevrolet and Pontiac applications equipped with the specified FS10 A/C compressor configuration.
This bypass pulley provides a solution for vehicles where an inoperable A/C compressor has been removed or needs to be bypassed while retaining the original equipment serpentine drive-belt arrangement. The pulley installs using the same mounting points as the original A/C compressor.
The Dorman 34209 uses a plastic pulley with an aluminum mounting bracket and features a 127 mm outside diameter serpentine pulley. Installation instructions are included. Because A/C compressor configurations can vary within a vehicle application, verify that the vehicle is equipped with the specified FS10 compressor configuration before ordering.

Purpose of the Bypass Pulley
The bypass pulley is intended for applications where an inoperable A/C compressor needs to be bypassed while retaining the original equipment drive-belt arrangement. Rather than changing the entire belt-routing configuration, the bypass assembly occupies the original A/C compressor mounting location and provides a pulley for the serpentine belt.
Construction
Dorman uses a plastic pulley and aluminum mounting bracket for this application. The pulley has a 127 mm outside diameter and is designed for a serpentine belt system.
Application-Specific Design
This is not a universal A/C bypass pulley. The Dorman 34209 is designed for specific GM applications using the FS10 compressor configuration. Verify the compressor type and vehicle application before ordering.

Application Verification
The vehicle applications above represent the model and year ranges associated with Dorman 34209. This bypass pulley is application-specific and is not intended to fit every A/C configuration within those model ranges. Confirm the vehicle's original A/C compressor type before ordering.
The specified compressor application for this pulley is FS10. A vehicle with a different compressor configuration may require a different bypass pulley.
- Verify the vehicle's exact application before ordering
- Designed specifically for the specified FS10 A/C compressor configuration
- Not a universal A/C compressor bypass pulley
- Vehicle model and year alone may not establish compatibility
- Verify the original compressor type and accessory-drive configuration
- Do not assume compatibility based solely on engine family or vehicle generation
- Verify the replacement pulley matches the vehicle and original compressor application before installation
- Inspect the serpentine belt for wear or damage before reinstallation
- Use the supplied installation instructions during installation
- Use the original A/C compressor mounting location as specified for the application
- Verify pulley alignment with the other accessory-drive pulleys before operating the engine
- After installation, verify proper belt tracking and clearance
Do not operate the engine if the serpentine belt does not track correctly. Follow the current manufacturer's installation instructions and verify all clearances before returning the vehicle to service.
