Ram 2500 engine produces squealing noise when cold, dealership indicates it's normal for 6.4 gas models on Ram 2500

Some Ram 2500 owners report experiencing a squealing noise from the engine, particularly when cold, which some dealerships classify as normal for 6.4 gas models. This noise may occur when the engine is warm and the visco fan is operating at full capacity, potentially taking time to idle and relieve strain in cold conditions. Additionally, owners have noted that the noise can be inconsistent, happening randomly at various speeds, including low speeds and during sharp turns. While some owners have been reassured that this noise is not indicative of a problem, it is advisable to consult with a dealership or mechanic if the noise persists or raises concerns, to rule out any underlying issues.
