Chevrolet Equinox low pitch whining sound correlated with RPM, possibly due to overspray on belt on Chevrolet Equinox

Some Chevrolet Equinox owners report experiencing a low pitch whining sound that correlates with the RPM, which may be caused by overspray on the belt. This overspray can lead to slippage, resulting in a noise that changes with engine speed. Owners are advised to inspect the belt for contamination and clean it thoroughly to prevent further slippage and noise. Additionally, ensuring the correct belt tension can help alleviate the whining sound. If the issue persists after cleaning and adjusting the belt, further inspection by a mechanic may be necessary to identify and resolve any underlying problems causing the noise.
