Solve the howling noise when stepping on the accelerator

If there is howling when stepping on the accelerator, replace the belt or bearing of the air conditioner compressor.

There will be noise when stepping on the accelerator, mostly because the compressor belt of the air conditioner is loose, or there is something wrong with the pulley bearing. Just find the corresponding problem and replace the faulty parts.

If the belt of air conditioner compressor is loose, it will not only make noise when accelerating, but also affect the refrigeration system of air conditioner. At this point, it is necessary to adjust the compressor belt. If the compressor belt slips, there will be squeaking when starting the air conditioner. It is best to replace the belt. Therefore, once the compressor belt is found to be loose or damaged, it must be handled in time.

Causes of noise when stepping on the accelerator

1, exhaust pipe leaks

When the exhaust pipe leaks, as long as the vehicle accelerates, it will lead to an increase in exhaust volume, and the vehicle is prone to a loud roar.

2. The throttle valve is dirty and blocked.

When the car accelerates, the load of the engine will rise. At this time, it is only necessary to increase the throttle opening. If the throttle opening is blocked because it is too dirty and can't open to the most suitable position, it will lead to the unsatisfactory mixture ratio of the engine and make noise when accelerating.

3. The engine stalled.

Engine cylinder missing means that one engine or several cylinders are not working normally. The common performance is that the car has insufficient power and the exhaust pipe is shaking badly. You can clearly hear the hum of engine oil.
