The Dorman 34152 is an economical aftermarket pulley designed to occupy the compressor’s mounting location and provide a smooth, reliable idler surface for the existing belt. It mounts in place of the compressor using the same bolt points, minimizing modification and downtime.\u003c\/p\u003e\n\n\u003ch3\u003eHow does this bypass pulley restore belt routing?\u003c\/h3\u003e\n\u003cp\u003eThe bypass pulley replaces the compressor’s rotating surface so the original serpentine belt can follow its factory path without rerouting.

The Dorman 34152 bypass pulley is aimed at vehicle owners and mechanics who want a cost-effective way to keep the serpentine belt functioning after an A\/C compressor fails or is removed. It’s well suited for repair shops handling older vehicles where replacing only the pulley is faster and less expensive than sourcing a compressor, and for do-it-yourselfers comfortable performing a direct swap using the factory mounting points. Always verify fitment for your exact vehicle and follow torque and installation guidance to ensure safe, reliable operation.\u003c\/p\u003e\n\u003csection class=\"product-faq-snippet\"\u003e\u003ch3\u003eFAQ\u003c\/h3\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Can I reuse my original drive belt with this bypass pulley?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: Yes.
