What Causes the Sound of Running Water When the Car Air Conditioner is On?

The reason why you can hear the sound of running water when the car air conditioner is on is: the condensed water from the air conditioner flows out of the car through a hose. Check if the central air conditioner hose has come loose. If it hasn't, the sound is caused by the refrigerant flowing and evaporating inside the compressor, which is a normal phenomenon. The functions of the air conditioner include: 1. Controlling the temperature inside the car; 2. Removing moisture from the air; 3. Drawing in fresh air for ventilation; 4. Filtering the air to remove dust and pollen. The method to use the car air conditioner is: 1. Turn on the AC switch; 2. Adjust the air vent selector knob—direct the vents upward when cooling and downward when heating; 3. Adjust the fan speed switch; 4. Adjust the air recirculation switch; 5. Adjust the temperature control knob.

How to Repair a Dent in an Aluminum Car Panel?

It is generally best to go to a 4S shop for repairs because their technicians are more skilled, while mechanics at external repair shops may not be able to fully restore the panel. For small dents on aluminum panels, you can use a fluorescent lamp to locate the dent and then slowly push it out from the inside of the panel using a pry bar until the entire dent is leveled. For areas that are difficult to repair using hammering or pry bar methods, an aluminum panel repair machine can be used for restoration.

What is the sequence for cleaning the engine compartment?

Engine compartment cleaning sequence: 1. Open the engine compartment for heat dissipation until the surface is not too hot to touch. Do not rinse with cold water when the compartment is at high temperature, as sudden cooling can cause damage to the engine compartment; 2. Seal the computer board, air intake, and parts of the car body that do not need cleaning. If water enters the air intake, it may prevent the engine from starting, and water on the computer board poses a risk of short-circuiting; 3. Use professional tools such as a steam cleaner for cleaning; 4. After cleaning, use an air gun along with a towel to blow and wipe dry all parts of the engine compartment; 5. Apply care solution to the plastic parts of the engine compartment to complete the cleaning.

What to Do When an Automatic Transmission Car Cannot Reverse?

If a large amount of hydraulic oil sprays out from the pressure test hole, it indicates that the main oil circuit pressure is normal, and the fault lies in the input shaft, planetary gear set, or output shaft of the automatic transmission. Check whether the linkage or cable between the automatic transmission control lever and the manual valve rocker arm is loose. If it is loose, it should be reinstalled. If only a small amount of hydraulic oil flows out from the main oil circuit pressure test hole, the oil pressure is very low or basically non-existent, the oil pan should be opened for inspection.
