Dorman A/C Compressor Bypass Pulley 34152 — Direct-Fit Replacement with Heavy-Duty Bearing and OEM Mounting

The Dorman 34152 A/C compressor bypass pulley lets you keep your vehicle's original drive belt in service after removing a failed A/C compressor.

When an A/C compressor seizes or leaks, replacing the entire system can be costly and time-consuming. The Dorman 34152 bypass pulley provides a straightforward, lower-cost option to restore belt routing and keep accessories driven without the damaged compressor. Built to match the original mounting points, this pulley is designed to fit in place of the removed compressor so the drive belt alignment and tension remain correct.

How does this bypass pulley work on my vehicle?

The bypass pulley replaces the A/C compressor pulley and uses the same mounting holes, allowing the factory drive belt to stay in use. It keeps belt tension and routing consistent so alternator, water pump and other accessories continue operating normally. Installation restores belt path without the compressor's rotating components.

• Replaces A/C compressor pulley with a fixed pulley assembly
• Uses original compressor mounting points for correct alignment
• Maintains factory belt routing and tension
• Eliminates drag and failure risk from a damaged compressor

Is the Dorman 34152 easy to fit and install?

Yes — the unit is designed for a straightforward swap using the compressor's existing bolts and brackets. No specialized machining or modification is required, though basic hand tools and standard mechanical knowledge are needed. Many technicians can complete the replacement in a short shop session.

• Direct-fit design uses original mounting points
• No cutting or welding required
• Compatible with factory belt without rerouting or custom tensioners
• Suitable for DIYers with basic automotive tools
