Why Does the Low-Pressure Pipe of a Car's Air Conditioner Freeze?

The reason for the low-pressure pipe of a car's air conditioner freezing is due to a malfunctioning expansion valve or a failed evaporator temperature sensor. Below are the related explanations for the faults: 1. Malfunctioning Expansion Valve: The low-pressure pipe of a car's air conditioner freezing is most likely caused by a malfunctioning expansion valve, which fails to sense the real-time temperature of the low-pressure pipe. If the temperature is too low, the low-pressure pipe will inevitably freeze (the expansion valve's opening cannot be adjusted lower). This issue is generally irreparable, and a new expansion valve needs to be replaced. 2. Failed Evaporator Temperature Sensor: It may be due to a failed evaporator temperature sensor. This component is designed to detect the surface temperature of the evaporator and transmit the data to the automatic air conditioning control unit. When the temperature drops below 2°C, the air conditioner will stop operating to prevent frost or ice formation. If the evaporator temperature sensor fails, it naturally cannot detect the corresponding temperature data, leading to the low-pressure pipe freezing. In this case, a new sensor needs to be replaced.

What is the best mileage interval for changing engine oil?

Engine oil should be changed every 5,000 kilometers or once a year, whichever comes first. The interval can be appropriately extended or shortened based on different driving conditions, driving habits, and other factors. Below are the steps for changing engine oil: Run the engine: Start the engine and let it reach operating temperature. Drain the oil: There is an oil drain plug underneath the vehicle. Simply unscrew the plug to allow the oil to flow out. Observe the color of the oil; if it appears black, it should be changed promptly.

What Gear Should You Use in an Automatic Car Wash?

Automatic car washes require the vehicle to be in neutral or N gear. Drive in using D gear, come to a complete stop, press the brake, shift to N gear, then release the brake. This is because automatic car wash systems use conveyor chains that will pull the vehicle forward when it's in neutral. Here are precautions for automatic car washes: Avoid washing under intense sunlight; refrain from washing in extremely cold weather; only use soft water (avoid hot water, alkaline water, or high-hardness water); do not randomly add detergents. Avoid washing under intense sunlight as rapid water evaporation may leave dried water spot marks on the vehicle surface. Refrain from washing in extremely cold weather as brush bristles may freeze and water pipes could rupture. Only use soft water - avoid hot water, alkaline water, or high-hardness water. These substances can damage the paint surface, leaving stains and film residue after drying. Do not randomly add detergents. While stubborn stains like asphalt, oil, bird droppings, or insect residue may require special attention, never use laundry detergent, scouring powder, or low-quality soap as these alkaline cleaners can strip protective oils from the paint and accelerate aging.

Why does the car shake when driving on the highway?

The following are common reasons for car shaking on the highway: 1. Incorrect front wheel alignment angle, excessive toe-in. 2. Low front tire pressure or tire imbalance due to repairs or other reasons. 3. Deformed front wheel rims or unequal number of tire bolts. 4. Loose installation of transmission system components. 5. Bent drive shaft, dynamic imbalance, or deformed front axle. 6. Failed shock absorbers, inconsistent stiffness of front leaf springs, or deformed frame. The following are precautions for driving on the highway: 1. Thoroughly inspect the entire car before entering the highway. It is best to get a free inspection at a 4S shop to eliminate potential hazards. 2. Accelerate quickly to over 100km/h before merging into the main lane. 3. Check the speedometer frequently and slow down in advance when exiting the highway or entering a ramp. 4. Strictly adhere to the speed limit to avoid speeding. 5. Signal before overtaking. 6. Handle situations ahead in advance. 7. Hold the steering wheel with both hands, mainly using the throttle to control speed. Avoid emergency braking, sharp turns, or single-handed control. 8. Take timely breaks in service areas.
