Here are the methods to repair a blocked expansion valve: 1. For dirt blockage, if it is not very severe, replacing a dry filter is sufficient; if it is very severe, it is necessary to clean the impurities in the system pipeline again, vacuum, and recharge the refrigerant. 2. For slight ice blockage, you can apply a hot towel to the ice blockage area; if the ice blockage is more severe and has affected the normal operation of the system, it is necessary to clean the moisture in the system pipeline again, vacuum, and recharge the refrigerant. 3. Expansion: The main cause of dirt blockage is the presence of impurities in the system, such as welding slag, copper chips, iron chips, fibers, etc. The cause of ice blockage is excessive moisture in the system.

What to Do When a Tire Bulges?

Tire bulging requires immediate replacement of the new tire. The bulging of a car tire is caused by the breakage of the internal cord fabric, which cannot be repaired and must be replaced. Tire bulging occurs due to tire aging and frequently driving quickly over speed bumps or hitting large potholes on the road. Car tires are one of the important components of a vehicle, directly in contact with the road surface. Together with the car suspension, they help to cushion the impacts encountered during driving, ensuring good ride comfort and smooth driving performance. They also ensure good adhesion between the wheels and the road surface, improving the vehicle's traction, braking, and maneuverability.

What is the difference between natural cracking and man-made damage in car glass?

The differences between natural cracking and man-made damage in car glass are as follows: 1. The area of scattered glass fragments differs: man-made damage results in larger fragment areas; due to internal stress without external impact, naturally cracked glass has smaller scattered areas. 2. The initiation points differ: man-made damage typically has initiation points at the glass edges, usually caused by edge damage or hard contact, while natural cracking originates from the center of the glass, featuring a butterfly-wing-like pattern formed by two small polygons with visible black particles along their shared edge.
