Why Does the Engine Overheat and the Fan Not Rotate?

Engine overheating with the fan not rotating can be attributed to the following reasons: Insufficient engine coolant temperature: Most modern vehicle radiator fans operate based on electronic temperature control. Therefore, the fan typically only starts rotating when the engine coolant reaches the required temperature. If the temperature is too low, the radiator fan will not rotate. Relay malfunction: If the coolant temperature meets the requirements but the vehicle radiator fan still does not operate, the issue might lie with the fan relay. A faulty relay can prevent the radiator fan from functioning. Thermostat switch issues: Certain faults in the thermostat switch can also impact the operation of the vehicle radiator fan, so it is important to inspect this component as well.

Is there white adhesive in the engine compartment of a new car?

The presence of white adhesive in the engine compartment of a new car is a normal phenomenon. Anti-rust and leak-proof adhesive: All welded joints of the car are coated with adhesive because the production line cannot individually grind and paint each joint for every car. This situation is normal and does not affect safety. Nowadays, joint-venture cars produced domestically often have this issue of rough workmanship, with many welded areas left unrefined. Most cars have this problem to some extent—they may look neat on the outside, but areas like the engine compartment, which are not visible, often reveal many workmanship issues. Application of sealant: It serves the purpose of sealing the engine compartment, providing sound insulation, and waterproofing.

How Long Can a Shenzhen License Plate Be Retained?

Shenzhen's original vehicle license plate must be used on the vehicle for one year to retain the original license plate for one year. The original license plate can be used within one year from the date of completing the transfer, cancellation, or relocation procedures of the original vehicle. After this period, the license plate cannot be continued to be used. The original owner can use the original license plate whether purchasing a new car or a used car. Below is additional information: 1. Handling of the original license plate: The original license plate must be submitted to the vehicle management office, which will uniformly process it as scrap. If the original owner uses a new or used vehicle for registration within the specified time, they can choose to use the originally retained license plate. The license plate needs to be reissued because the original vehicle license plate has been scrapped. 2. Precautions: The vehicle license plate must be used on the vehicle it is registered to. Once installed, the license plate must not be removed without authorization. During the use of the license plate, it must not be damaged or altered. If any of the above situations occur, the vehicle license plate must be reissued immediately. Vehicles without a license plate are not allowed to be driven on the road.

What Happens If You Drive After Unplugging the Front Oxygen Sensor?

Driving after unplugging the front oxygen sensor will result in increased fuel consumption and negatively impact the car engine's performance. Below is an introduction to the specific reasons and precautions for using the oxygen sensor: Explanation of Specific Reasons: The oxygen sensor does not function in the air-fuel ratio feedback control during engine idling. Disconnecting the oxygen sensor during idling has minimal impact on the engine. However, when the oxygen sensor is disconnected under engine load conditions, the engine will no longer be controlled by the air-fuel ratio feedback, leading to increased fuel consumption. The air-fuel mixture will become richer than when the oxygen sensor is connected, significantly worsening emissions and causing unstable power output. Precautions for Using the Oxygen Sensor: Drive as smoothly as possible under normal conditions. Unless in emergencies or poor road conditions, minimize severe shaking and impacts to the vehicle body, and avoid scraping the undercarriage. The oxygen sensor contains ceramic-sensitive components, and severe shaking or impacts may damage these parts. Pay attention to the sensor wiring. During routine vehicle maintenance, avoid excessive pulling of the wiring. Like other electronic devices, if the sensor's wiring is affected, leading to unreliable connections, it may disrupt the normal operation of the oxygen sensor. Be cautious when washing the car after turning off the engine, especially around the exhaust system. The exhaust pipe becomes very hot during use, and if it is accidentally rinsed with cold water during washing, the rapid cooling may cause the ceramic-sensitive components in the oxygen sensor to crack.

How many days should the car stay in the underground garage after tinting?

After applying window tint, the car can be parked in an underground garage. However, it is recommended to avoid washing the car within the first three days to prevent the film from peeling off due to moisture. Below is relevant information about car window tinting: 1. Functions: Blocks UV rays, especially during hot summers when sunlight is intense. The tint can reduce part of the visible light and UV rays, helping to lower the temperature inside the car; provides anti-shatter properties; enhances privacy, as the tint creates a visual reflection from the outside, making it harder to see inside the car. 2. Disadvantages of dark tint: While dark tint offers better privacy compared to light tint, it can impair visibility in dimly lit environments. The already poor lighting conditions, combined with the dark tint, make it difficult to observe the rearview mirror clearly. Light tint, on the other hand, provides better visibility and makes driving more manageable.

How to Identify Whether a New Car is a Stock Vehicle?

Here are methods to identify if a new car is not a stock vehicle: 1. Manufacturing time: Check the nameplate near the car door, which usually indicates the manufacturing time. Generally, a new car should have been manufactured within the last three months. If the manufacturing time is significantly longer, it is likely a stock vehicle. 2. Time symbols: These are the small dot markings in the corners of the glass, representing the manufacturing time of the glass. Check if the time on both sides of the glass matches. If not, it indicates that one piece has been replaced. 3. Tire wear: New tires have a layer of "tire hairs" when they are first manufactured, which wear off after a few hundred kilometers of driving. When picking up a new car, carefully inspect the tire hairs on all four tires to see if they are still present. 4. Pedal wear: Check for mud stains or wear marks in the gaps of the pedals, as well as excessive wear on the floor mats under the pedals. If present, it suggests the car has been driven for a long distance.
