Motormite 34187 A/C Compressor Bypass Pulley

The Motormite 34187 is an A/C Compressor Bypass Pulley — a cost-effective alternative to replacing a failed or seized air conditioning compressor. When an A/C compressor fails, it can prevent the serpentine belt from routing correctly, leaving the vehicle undriveable. This bypass pulley installs in place of the removed compressor, allowing the original OE-size serpentine belt to continue driving all remaining accessories without interruption.

Key Features:

• Cost-effective solution — retains the use of the standard OE drive belt after a failed A/C compressor is removed
• Direct-fit installation — mounts to the same bolt points as the original A/C compressor for a straightforward swap
• Durable construction — quality-grade bearing and components engineered for long service life
• Quality tested — undergone extensive testing to ensure proper fit and lasting performance
• Part of the Motormite HELP! line — a solution-driven category from Dorman Products designed for practical, affordable repairs

The Motormite 34187 A/C bypass pulley is an ideal solution for vehicles where A/C compressor replacement is cost-prohibitive, allowing the engine's accessory drive system to function normally while the air conditioning system remains disabled.
