It doesn't matter if the windshield washer fluid overflows. The washer fluid filler port is generally wide and open for easy filling. If needed, you can install a funnel on the port when filling. During the process of adding washer fluid, if it spills out, there's no need to worry. The washer fluid contains alcohol components which evaporate easily. Low-quality washer fluid: Most are made by mixing water and alcohol, which not only damages the gloss of the car paint and the hardness of rubber strips but may also cause color differences, swelling, or dissolution of rubber or other plastic parts in severe cases. If washer fluid is accidentally spilled outside during filling, it may flow near the air conditioning intake. The odor from the evaporating washer fluid can also enter the cabin through the car's air conditioning ventilation ducts. The gases emitted by low-quality washer fluid are harmful and can become an invisible killer to the owner's health. High-quality washer fluid: Premium washer fluid is made from deionized water and various environmentally friendly additives, featuring functions such as cleaning, antifreeze, antistatic, and anti-corrosion. Some better-quality washer fluids also have properties like rapid snow and ice melting, anti-glare, and anti-fog, playing a significant role in improving driving safety.

What is the working principle of a rack and pinion steering gear?

The working principle of a rack and pinion steering gear is: 1. The pinion gear of the steering gear is located at the lower end of the steering spindle and meshes with the steering rack; 2. When the steering wheel is rotated, the pinion gear in the steering gear turns, driving the rack in the steering gear to move in the direction of the steering wheel's rotation; 3. The movement of the steering rack is transmitted to the steering knuckle arm through the ends of the steering rack and the tie rod ends, thereby turning the wheels. The main components of a rack and pinion steering gear are: pinion gear, rack, adjusting screw, housing, and rack guide block. The characteristics of a rack and pinion steering gear are: 1. Simple and compact structure; 2. High transmission efficiency; 3. High reverse efficiency, which transmits the impact force between the steering wheel and the road surface to the steering wheel.

What does it mean when the engine fault light comes on and then goes off?

The reason the engine fault light comes on and then goes off is: the internal temperature of the engine is relatively low, and the gasoline atomization is poor. The engine fault light indicates the following situations: 1. Comes on and then goes off automatically: normal condition; 2. Stays on: indicates a mechanical fault in the vehicle's engine that requires repair. Vehicle fault lights are categorized into: 1. Notification type: indicates the vehicle's current state is abnormal or operation is incorrect, such as the seat belt reminder light or door open reminder light; 2. Warning type: indicates the vehicle has a fault that needs repair, such as the engine fault light or oil pressure fault light; 3. Indicator type: shows some basic conditions of the vehicle, indicating the current working state, making it easier to understand various functions and states of the vehicle, such as the lighting system indicator, water temperature indicator, or fuel level indicator.

Should a Slowly Leaking Tire Be Repaired?

It is not recommended to immediately repair a slowly leaking tire. Frequent repairs and repeated disassembly and assembly can cause damage to the vehicle's rims and tires. The following are situations where it is not advisable to restore the tire to normal working condition through repair: 1. Large-area scratches or damage on the sidewall. 2. A 'penetrating' hole or puncture in the tread with a diameter exceeding 5mm is not recommended for repair. 3. If the entire bead (inner tire ring) is damaged or deformed, the tread is twisted, deformed, corroded by chemicals, or the tire has been 'rolled over' while underinflated, it is not recommended to restore it through 'repair'; instead, replacing the tire is advised. 4. In cases of severe damage, exposed steel belts, severe delamination, bubbling, etc., the above repair methods are not recommended, and replacing the tire is the better option.

What to Do When the Car Air Conditioner Emits Odors in Heating Mode?

The main reasons for odors when using the heater are external exhaust fumes, accumulated smells inside the car, placed air fresheners, as well as human sweat and body odor, which can enter the car's interior. When the air conditioner is used, these odors encounter the warm and moist surface of the evaporator, blending with the air, and are then released when the air conditioner is in operation. Methods to eliminate odors include: 1. High-temperature drying of the evaporator. 2. Minimize the use of acidic car air fresheners. 3. Use cleaning agents to sterilize the external circulation air ducts. 4. Reduce sources of odors inside the car as much as possible. 5. Alternate between primary and spare filters.
