Dodge Challenger whining noise during startup and operation, possibly from motor or water pump on Dodge Challenger

Some Dodge Challenger owners report experiencing a whining noise during startup and operation, which may indicate several underlying issues. A high-pitched sound could suggest a failing alternator, potentially triggering the battery light. Additionally, the noise might stem from the accessory drive system, particularly the water pump, which can develop bearing play over time. Other components on the belt drive, such as the AC condenser or idler, may also contribute to the whining. Owners can diagnose the source by removing the serpentine belt and starting the engine; if the noise disappears, it points to a belt-driven component issue. Furthermore, a whining noise may be linked to the power steering pump or a loose drive belt, especially if it is more pronounced during cold starts and lessens as the engine warms. Prompt attention to these potential causes is crucial to avoid further complications.
