What's the sound of water on Buick Hideo accelerator?

As soon as the Pacific Auto Network stepped on the accelerator, it heard the sound of running water, which should be the accumulated water generated by the air conditioning system or the accumulated water left by the car. Because the warm air of the air conditioner comes from the circulation of engine coolant, and the pipeline position of this part is relatively high, the air is trapped there after replacing the coolant, and a certain amount of water may be formed after a long time.

If the car brakes and hears the sound of water while driving, it means that there is water on the car, which may be that the exhaust pipe is loose or damaged, or that cold water flows through the air conditioner heater. It is suggested that the owner check whether the water in the water tank of the car is reduced, and emptying the air in the water tank can eliminate the sound of this water.

Causes of abnormal sound of throttle valve

1. Throttle is stuck due to carbon deposition, so clean the throttle;

2. The supporting pin of the accelerator pedal is worn. Adding butter can solve the problem. If it doesn't work, replace it.

3. The accelerator cable is not installed correctly. If it is an electronic accelerator, please check the accelerator pedal mechanism and the accelerator pedal sensor.

The operation of the accelerator pedal should be based on the right heel stepping on the cab floor as the fulcrum, and the sole of the foot lightly stepping on the accelerator pedal, stepping down or relaxing with the extension and flexion of the ankle joint. When stepping on the accelerator pedal, the force should be gentle, so that you can step on it gently and lift it slowly.

When you step on the accelerator, you can clearly hear the sound of water flow, and the approximate position of the sound should be in the dashboard or engine compartment. When I opened the lid, I found that there was a "cooing" sound in the Xu Shui pot of the engine when I stepped on the gas pedal. Open the lid of the water tank, and the water in the kettle keeps bubbling. Subsequently, we also found that after the engine water temperature reached normal temperature, the water inlet pipe still had no temperature, indicating that the thermostat was not opened.
