Why is the GLC engine noise loud?

1 Answers

07/29/25 7:01pm
The reasons for the loud engine noise in the GLC are as follows: 1. Incorrect engine oil condition: Engine oil is an important component for engine lubrication. When there is an issue with the engine oil, it affects the engine's operation. If the oil viscosity is too high, it can easily cause operational problems in the engine, reduce lubrication effectiveness, and lead to friction during engine operation, resulting in noise. 2. Insufficient belt tension: When the engine belt tension is insufficient, the engine will produce sharp noises during operation, severely affecting the driver's experience. Solution: In such cases, adjusting the tension of the engine belt can prevent the noise.

How to Operate an Electronic Parking Brake in a Car?

Electronic parking brake operation method: 1. With the foot on the brake and the vehicle stationary, pull the electronic parking brake button upward to activate it; 2. With the foot on the brake and the vehicle stationary, press the electronic parking brake button downward to deactivate it. The electronic parking brake, also known as the electronic parking brake system, integrates the temporary braking function during driving with the long-term braking function after parking, and achieves parking braking through electronic control. The electronic parking brake technology uses electronic control to implement parking braking, with the same working principle as the mechanical handbrake—both rely on the friction generated between the brake disc and brake pads to control parking braking. The control method has evolved from the previous mechanical handbrake lever to an electronic button.

What are the effects of overfilling transmission fluid?

The effects of overfilling transmission fluid include: 1. Increased oil pressure; 2. Higher risk of oil seal leakage; 3. Increased resistance in internal gears. Methods for maintaining the transmission are: 1. Regularly change the transmission fluid; 2. Frequently check the fluid level; 3. Avoid coasting in neutral; 4. Periodically clean the transmission; 5. Avoid forcing the gearshift; 6. Reduce the time spent idling to warm up the engine. The functions of the transmission are: 1. Changing the transmission ratio to expand the range of torque and speed variations of the driving wheels, adapting to frequently changing driving conditions and allowing the engine to operate under favorable conditions; 2. Enabling the vehicle to reverse while maintaining the engine's rotation direction; 3. Using neutral to interrupt power transmission, allowing the engine to start, idle, and facilitating gear shifting or power output.
