1. Serpentine belt: This belt is responsible for driving various engine components, such as the air conditioning compressor, power steering pump, and alternator. If the serpentine belt is loose or damaged, it can squeal when the engine is running.
2. Timing belt: This belt synchronizes the camshaft and crankshaft, ensuring that the engine's valves open and close at the correct times. A worn or damaged timing belt can also cause a squealing noise.
3. Drive belt: This belt is used in some older cars to drive the water pump. If the drive belt is loose or damaged, it can squeal when the engine is running.
If you hear a squealing noise coming from your car engine, it's important to have it inspected by a qualified mechanic to determine which belt is the source of the noise and have it replaced if necessary.
