How to Determine if the Expansion Valve is Malfunctioning?

Common failures of the expansion valve include blockages, which can be measured and diagnosed using a pressure gauge. Below are detailed explanations of the expansion valve: 1. Expansion valve blockage. When the car's air conditioning is turned on, it may fail to cool, and measuring the pressure in the air conditioning lines with a pressure gauge will reveal excessively high high pressure and excessively low low pressure, indicating a faulty expansion valve. 2. Symptoms of a damaged expansion valve include the low-pressure pipe not being cold to the touch, frosting on the dryer and condenser, abnormal high and low pressures, and abnormal temperature in the high-pressure pipe. 3. The expansion valve is a crucial component in the refrigeration system, typically installed between the liquid reservoir and the evaporator. It functions as a throttle, converting high-temperature, high-pressure liquid refrigerant into low-temperature, low-pressure mist-like hydraulic refrigerant through its throttle orifice, creating conditions for the refrigerant to evaporate.

Is It Necessary to Apply Film on the Car's Front Windshield?

Applying film on the car's front windshield is necessary. Here are the benefits of applying film to the front windshield: 1. Applying film to the car's front windshield is beneficial because it effectively blocks ultraviolet rays from outside the car, preventing excessively high temperatures inside the vehicle during summer, which could otherwise affect the driver's comfort. 2. After applying the film, it reduces the impact of oncoming vehicle lights on the driver's vision during nighttime driving, thereby improving driving safety. Here are some precautions for applying car film: 1. When applying the film, the color of the film for the front windshield should be slightly lighter, or a colorless glass film should be used. It is crucial not to obstruct the driver's view when applying the film to the front windshield. 2. The film on the four door windows should not be too dark, as it may impair the driver's judgment of the surroundings at night. When applying film to the front driver and passenger windows, it is advisable to leave a triangular area near the rearview mirror. This allows the driver to better observe the rearview mirror and prevents safety hazards caused by an inability to see vehicles behind.

Which tire models are interchangeable with 80/90-10 tires?

80/90-10 tires are interchangeable with 3.00-10 and 90/90-10 models, including tubeless tires, and come with both inner and outer tires. Although there is a difference in thickness after inflation between the two types of tires, their widths are the same, and the wheel hub diameters for installation are identical, allowing them to be swapped. Explanation of wheel specifications: For the 3.00-10 specification, 3.00 refers to a section width of 3.0 inches, and 10 indicates a rim diameter of 10 inches (1 inch = 25.4mm). 80/90-10 represents a section width of 80mm, with 90 referring to an aspect ratio of 90%, and 10 indicating a rim diameter of 10 inches (1 inch = 25.4mm). Therefore, the two specifications mentioned above are interchangeable with 80/90-10 tires. There is another common way to express tire specifications, such as the commonly used 205/55r16. Here, 205 represents a tread width of 205 millimeters, 55 stands for the aspect ratio, meaning the sidewall height is 55% of the tread width, and 16 indicates that the tire can be mounted on a 16-inch rim.

What are the precautions for driving in the rain?

There are several precautions for driving in the rain: 1. Slow down: Visibility is low in rainy conditions, and the vehicle's emergency performance, such as braking distance, is reduced. Therefore, it is important to slow down in advance, leaving enough time and space to handle situations and ensure safety. 2. Maintain distance: Visibility is obstructed when driving in the rain, so it is crucial to keep a safe distance from other vehicles, constantly observe the distance between the front and rear vehicles, and increase the safety margin. Especially stay away from large vehicles, as they can block your view, and the water depth that large vehicles can pass through may not be suitable for smaller cars. Additionally, large vehicles can easily splash water, interfering with the driving of smaller cars.

What does the MODE button in a car mean?

The MODE button in a car is used to switch between different modes, making usage more convenient and reflecting intelligent functionality. Below are two common functions of the MODE button: 1. If the MODE button is located on the central control panel, it is used to switch the air conditioning airflow modes, typically cycling between foot-level, head-level, and windshield defrost modes. 2. If the MODE button is located on the steering wheel, it is used to switch between multimedia modes, usually cycling through FM/AM/online radio/USB/local storage/Bluetooth music modes.

What are the reasons for a car door not opening?

There are several main reasons why a car door may not open: 1. Child lock is engaged: Most rear doors of vehicles have a child lock, marked with a child symbol near the edge of the door. If it is accidentally engaged and the door is closed, the door will not open. 2. Door lock cable malfunction: If the cable malfunctions, it directly affects the lock mechanism, preventing the door from opening. 3. Door hinge or lock post deformation: When the door is subjected to external force, it may cause deformation of the door hinge or lock post, which is another reason why the door may not open.
