What causes the abnormal noise from the belt during cold start of the Teana?
1 Answers
The causes of abnormal noise from the belt during cold start of the Teana are: 1. Aging of the drive belt: The main component of the drive belt is rubber, which becomes hard and brittle in winter, reducing the friction coefficient. The motor belt not only drives the generator but also powers the compressor, power steering pump, water pump, and other accessories. 2. Severe belt wear: Severe wear on the old belt drastically reduces the contact area between the belt and the pulley. In this case, pressing the belt hard will cause it to sink deeply into the pulley groove. 3. Insufficient belt tension: When the tension is insufficient, the belt is prone to slipping. Modern belts are self-tensioning, and a loose belt can also cause abnormal noise.
