It may be related to the fan belt or the balance of the fan blades, or possibly due to a dirty radiator causing poor heat dissipation, which affects the air intake volume. This leads to the electric fan increasing its rotation speed, resulting in increased wind noise. This issue does not affect daily use. It is recommended to clean the radiator and fan blades, and check if the fan's mounting screws are loose. Below is an introduction to the electric fan: 1. Composition: The electric fan is designed to prevent the engine coolant temperature from becoming too high. It consists of a sensor, electric fan, chip, etc. 2. Function: When the coolant temperature generally exceeds 90 degrees, the sensor activates, and the electric fan turns on to lower the coolant temperature. In winter, when temperatures are lower and the coolant temperature is also lower, the electric fan usually does not operate, protecting the engine from working in excessively cold or hot conditions.

Does keeping the car in N gear affect the transmission?

Keeping the car in N gear can harm the transmission. In an automatic transmission, there is a designed gap between the parking pawl and the parking gear. When the driver shifts into P gear and releases the brake pedal, the transmission shaft still has a small rotation angle, causing a slight jolt in the car until the two components engage and the car comes to a complete stop. More information about the transmission is as follows: 1. Transmission wear is mostly not caused by shifting gears but by lack of maintenance. 2. The transmission, like the engine, is one of the three major components of a car. Regular drivers should know that engine oil needs to be changed periodically, and the same applies to transmission fluid.
