- Serpentine belt: The serpentine belt is a long, thin belt that drives various engine components such as the alternator, power steering pump, and air conditioning compressor. If the serpentine belt is loose, worn out, or damaged, it can produce a squealing noise.
- Tensioner pulley: The tensioner pulley is a pulley that helps keep the serpentine belt tight. If the tensioner pulley is loose, worn out, or damaged, it can cause the serpentine belt to vibrate and produce a squealing noise.
- Idler pulley: The idler pulley is another pulley that helps keep the serpentine belt tight. If the idler pulley is loose, worn out, or damaged, it can also cause the serpentine belt to vibrate and produce a squealing noise.
- Water pump: The water pump is a pump that circulates coolant throughout the engine. If the water pump is leaking or damaged, it can cause the serpentine belt to slip and produce a squealing noise.
- Alternator: The alternator is a device that generates electrical power for the vehicle. If the alternator is malfunctioning, it can cause the serpentine belt to slip and produce a squealing noise.
- Power steering pump: The power steering pump is a pump that provides hydraulic pressure to the power steering system. If the power steering pump is malfunctioning, it can cause the serpentine belt to slip and produce a squealing noise.
If you are experiencing a squealing noise from your Dodge Durango, it is important to have it inspected by a qualified mechanic to determine the source of the noise and have it repaired as necessary.
