1. Loose or damaged fan belt. The fan belt is responsible for driving several essential components in the engine, such as the alternator and water pump. If the fan belt is loose or damaged, it can generate a high-pitched screeching sound.
2. Worn brake pads: Worn brake pads can make a screeching or squealing noise when you brake. This sound is caused by the metal backing of the brake pads rubbing against the rotors.
3. Power steering pump problems. A faulty power steering pump can generate a screeching noise when you turn the steering wheel.
4. Transmission issues. A screeching noise can sometimes indicate transmission problems, such as low transmission fluid or worn-out bearings.
5. Bad wheel bearing: When the wheel bearing goes bad, it can produce a screeching sound, particularly when the car is in motion.
It is important to identify the source of the screeching noise to ensure the safety and performance of your vehicle. If the noise persists or becomes louder, it is recommended to have your car inspected by a qualified mechanic.
