What to Do When the Car Generator Belt Makes Abnormal Noises?

[Susanna]

Abnormal noises from the car generator belt are usually caused by the smooth wear between the belt and the pulley contact surface. These noises typically occur when the engine speed changes rapidly, and sometimes when the load on the belt-driven accessories increases. Below are the specific steps to address the issue: 1. Use a 14mm wrench on the generator's fixing screw. 2. Rotate counterclockwise to loosen the fixing screw. 3. Loosen the generator tension adjustment screw. 4. Rotate the tensioning screw clockwise. 5. After the generator belt is tightened, secure the fixing screw.
