Serpentine Belt / Drive Belt (Aftermarket) — Dodge Charger / Challenger / Chrysler 300 (3.6L V6)

The Serpentine Belt (Drive Belt) serves as the vital lifeline for the accessory drive system on the 3.6L Pentastar V6 engine. This heavy-duty belt transfers rotational power directly from the crankshaft pulley to drive critical auxiliary components, including the alternator, A/C compressor, and water pump. This premium aftermarket replacement is constructed from advanced reinforced EPDM synthetic rubber, engineered to offer outstanding flexibility, high resistance to thermal cracking under intense engine bay heat, and whisper-quiet operation without slipping or squeaking. It is the ideal, dependable solution for preserving accessory efficiency and maintaining proper engine cooling.

Technical Specifications

Technical Note: It is highly recommended to visually inspect the serpentine belt every 60,000 to 80,000 km. Critical warning signs indicating the need for immediate replacement include dry-rot hairline cracks along the inner ribbed grooves, continuous "squealing" or "chirping" noises upon starting the engine, or structural fraying along the outer belt edges.

Pro Tip: When installing the new belt, carefully trace the routing path against the official Belt Routing Diagram decal found inside the engine compartment. Additionally, verify that the belt tensioner pulley rotates smoothly and maintains adequate spring pressure; a weak or failing tensioner will cause your new belt to slip, accelerate wear, and fail prematurely.
