Should You Turn Off the Air Conditioning Before Parking?

Is it necessary to change the transmission oil for sedans?

It is necessary to change the transmission oil for sedans. The transmission oil of a car should be replaced every 3 to 4 years, or when the mileage reaches 60,000 to 80,000 kilometers. If the transmission oil is not replaced after prolonged use, its lubrication effect will weaken, leading to ineffective lubrication, which can affect the operation of the hydraulic system and cause unstable pressure in the car's transmission. Methods for changing transmission oil: 1. Gravity replacement: Loosen the bolt of the oil pan and let the transmission oil flow out by gravity; 2. Circulation machine replacement: Store the new transmission oil inside the circulation machine, connect the transmission and the circulation machine through pipeline interfaces, and the new oil will push out the old oil under the action of the circulation machine; 3. Remove the oil pan for oil change, and the transmission oil filter can also be cleaned at the same time.

What is the reason why the BYD Qin's air conditioner only blows air but does not cool?

Reasons why the air conditioner only blows air but does not cool: Insufficient refrigerant: This leads to an insufficient amount of refrigerant in the air conditioning system's pipelines, resulting in reduced pressure and less heat being removed, making it feel like the air conditioner is only blowing air without cooling. In this case, you need to observe through the sight glass above the dryer. During normal operation of the air conditioner, if there are continuous, slow bubbles in the sight glass, it indicates insufficient refrigerant. If obvious bubble flipping is observed, it means the refrigerant is severely insufficient. Excessive refrigerant: There is a required proportion of refrigerant in the air conditioning system. If the proportion is too high, it can affect heat dissipation. Similarly, if too much cooling oil is added during maintenance, it can also reduce the heat dissipation capacity of the cooling system. Aging or loose belt: If the drive belt of the car's air conditioning compressor is loose, the compressor may slip during operation, leading to reduced transmission efficiency. This causes the compressor's speed to drop, reducing the delivery of compressed refrigerant, which results in the car's air conditioner not cooling.

What are the effects of turning off the car without turning off the air conditioning?

If the air conditioning is not turned off before shutting down the car, the compressor will start running together when the car is started next time, increasing the load on the motor. Generally, it is not advisable to turn on the air conditioning when the engine is cold, as it may damage the engine. Turning off the air conditioning about 2 minutes before shutting down the car allows the cold air in the pipes to be discharged in time, preventing mold and bacterial growth. Effects of turning off the car without turning off the air conditioning: If the air conditioning is not turned off in advance, a large amount of moisture will remain on the evaporator, which may cause blockages or bacterial growth. It is recommended to turn off the AC switch when reaching 2 kilometers from the destination and use natural wind to dry the moisture on the evaporator, which can reduce fuel consumption. When restarting the engine without turning off the air conditioning, the air conditioning will not affect the starter's operation. When starting the vehicle, most cars will temporarily stop supplying power to unnecessary electrical devices, so the blower and compressor electromagnetic clutch will not work during the starter's operation. Conclusion: Although the air conditioning in high-end models is automatically controlled, it is recommended to turn off the air conditioning before shutting down the car.

Can the Warranty Still Be Applied After Water Damage Repairs?

After a vehicle has been repaired for water damage, the warranty cannot be applied. Below is relevant information about vehicle warranties: 1. Vehicle Warranty Period: The warranty period or mileage for the entire vehicle is determined by the manufacturer's publicly announced data. Generally, it is two years or 60,000 kilometers, or three years or 100,000 kilometers. Some manufacturers may offer warranty mechanisms that exceed these time and mileage limits. 2. Requirements for Vehicle Warranty Use: The vehicle warranty covers free replacement of various parts if they are confirmed to be damaged due to quality issues rather than human factors, such as speedometers or air conditioning components. If these issues occur within the warranty period or specified mileage, they can be repaired for free. The powertrain warranty refers to the engine and transmission. If these components experience quality issues, they will be covered under warranty, provided that regular maintenance is performed at authorized service centers as specified in the maintenance manual. In the above cases, free replacement is available if the issue is confirmed to be a quality problem. However, if the damage is caused by improper operation, the manufacturer will not provide warranty coverage.

Why Does the Car Smell Bad?

Plastic rubber and low-quality decorations can cause unpleasant odors in the car. Here are the specific details: Odors produced by plastic leather or rubber products: Most accessories are plastic parts, made from materials like leather or rubber. Therefore, if these materials are present, they will inevitably produce certain odors, which are mainly noticeable in new cars. After purchasing a new car, it is important to promptly remove the original plastic packaging inside the car. If not removed in time, the plastic packaging can also seal the car's decorations tightly, preventing odors from dissipating, thus leading to unpleasant smells. Additionally, placing some activated charcoal in the car can help absorb these odors. Low-quality decorations: To save money, many people might purchase decorations online. However, there are numerous styles available online, so it is possible to end up buying decorations made from substandard materials. Once installed in the car, these decorations can release large amounts of harmful gases, resulting in poor air quality inside the car and even causing unpleasant odors. Therefore, when buying such items, avoid opting for cheap, counterfeit products and instead choose high-quality items whenever possible.

How to Remove Reflective Stickers from Cars?

Methods for removing reflective stickers from cars: 1. Before removing the reflective stickers, wash the vehicle and wipe it clean to facilitate the detection of residual adhesive around the stickers; 2. After cleaning and wiping, use a hairdryer to heat the stickers. A heat gun specifically designed for anti-explosion film can be used. Heat one corner of the sticker, then lift it with a plastic scraper and gently pull it; 3. Then, direct the hot air at the junction between the sticker and the car body, pulling it off slowly while blowing. The optimal positions for reflective stickers on cars are on both sides of the front and rear bumpers and the wheel arches, but they must not block the license plate. It is important to note that too many reflective strips on small cars can be overly bright and affect nighttime driving safety.
