Detailed Description

This Dorman A/C compressor bypass pulley, part number 34299, is used when the air conditioning compressor has failed but the drive belt still needs to remain in service. By replacing the compressor function with a bypass pulley assembly, it helps maintain belt operation without requiring a full A/C compressor replacement. It is a direct-fit solution for 2003-2008 Dodge Ram 1500, 2003-2008 Dodge Ram 2500, and 2003-2008 Dodge Ram 3500 models equipped with the listed compressor type. This part cross-references UAC (e.g., CO10802C, KT4900) for the same application.

What It Helps Solve

• Broken or seized A/C compressor that prevents normal belt operation
• Need to keep the serpentine belt in place after compressor failure
• Noise or drag caused by an inoperable compressor pulley assembly
• Temporary or permanent bypass of the compressor on Ram truck applications
• Restoration of accessory drive function without replacing the compressor

Installation Notes and Tips

Verify compressor type 10S17E and confirm belt routing before installation. Mounting hardware is not included, and installation instructions are not included. Because this part is built around the original belt path, careful alignment is important to maintain proper serpentine belt tracking on 2003-2008 Dodge Ram 1500, Ram 2500, and Ram 3500 models. Confirm the vehicle year and compressor configuration against the existing unit before ordering Dorman 34299.

Quality Assurance

Dorman supplies replacement components for repair applications where restoring function is more practical than replacing the full assembly. Part number 34299 is built with an aluminum bracket and plastic pulley to support a serviceable bypass solution for the specified Ram truck fitments.
