Is Double-sided Tape Needed for License Plate Installation?

Double-sided tape is not required for license plate installation. License plates, commonly known as vehicle plates, refer to the plates mounted on the front and rear of a vehicle. They are typically made of aluminum, sheet metal, plastic, or paper, and display the vehicle's registration number, registration region, or other relevant information. Below are some important points to note during the plate installation process: 1. Vehicle Certification: When registering the vehicle at the DMV, the vehicle's certification must be submitted to the DMV staff for archiving. 2. Purchase Invoice: Whether buying from a 4S store or an auto dealership, the purchase invoice must be kept safe, as it is essential for vehicle registration. Without this invoice, the vehicle cannot be registered. The purchase invoice must also be submitted to the DMV staff for archiving during the registration process.

What is the function of engine lubricant?

Engine lubricant serves the following purposes: reducing friction between moving parts of the engine, ensuring smooth engine operation, improving mechanical efficiency, cleaning the engine and removing residual impurities in the filter. Engine lubricant is required wherever there is relative motion between metal components in the engine. If the engine is not protected by lubricant during operation, dry friction will occur in tightly fitted areas such as between the piston and cylinder wall, or between the connecting rod bearing and crankshaft. The heat generated in a short period of time can be sufficient to melt the metal, causing damage to components or even seizure (such as piston scuffing or crankshaft bearing seizure), leading to engine failure. Therefore, in daily use, engine lubricant must be regularly inspected, replenished or replaced.

What are the methods for throttle valve matching?

1. Manual matching: Some vehicles use cable-operated throttle valves. After replacing the throttle valve, manual matching can be performed by turning the ignition key on and off several times. The vehicle's computer will then delete the memory of the old throttle valve and store the data of the new one. If the vehicle starts and runs normally, the matching is complete. 2. Power disconnection matching: After replacing the throttle valve, you can disconnect the negative terminal of the battery and wait for one minute before reconnecting it. This process will clear the original memory of the vehicle's computer and restore it to factory settings. If the vehicle starts and runs normally, the matching is successful. This method is only suitable for low-end vehicles and cannot be used for high-end vehicles. 3. Diagnostic tool matching: After replacing the throttle valve, a dedicated automotive diagnostic tool can be used for matching. After entering the system, select the action test and click "adaptive value reset to zero." Repeat this process several times. If the vehicle starts and runs normally, the matching is successful. 4. Using the old throttle position sensor for matching: If idle speed instability or excessively high idle speed occurs after installing a new throttle valve, you can unplug the connector of the newly installed throttle position sensor and plug it into the old throttle position sensor. Start the vehicle, and if it runs normally, you can then turn off the engine and reconnect the wiring harness to the new throttle valve. 5. Electronic throttle manual matching: Most modern engines use electronic throttle valves, and the matching method differs from that of cable-operated throttle valves. After replacing the throttle valve, turn on the ignition switch. You will hear the sound of the throttle motor operating. Wait for about one minute until the throttle motor operates again. At this point, you can start the vehicle directly. If the vehicle runs normally, the matching is successful.

Why is there no response when inserting the car key?

There are several reasons why a car key may not respond: the car is out of fuel, the battery is dead, the gear is in the wrong position, the spark plug is defective, the fuel line is clogged, the fuel pump is damaged, or the car has aged. 1. The battery is not charged. If the battery is not charged, it may prevent the car from starting. You can check if the battery is charged by honking the horn—if it sounds, it indicates the battery is discharged. 2. Incorrect gear position. This makes operation more convenient and simple. If the gear is not placed correctly when starting, it may prevent the car from igniting. 3. Issues with the spark plug. Whether the car can start depends on whether the spark plug is functioning properly. If the car does not start, check the spark plug for faults. 4. Clogged fuel line. If low-quality fuel is frequently used to save money, impurities in the fuel may clog the fuel line. Timely cleaning of the fuel line is crucial. 5. Damaged fuel pump. The fuel pump is a critical component for gasoline-powered cars. If the fuel pump is damaged, it may cause a fuel supply failure, preventing the car from starting. First, check whether the power wire to the ignition switch has electricity. If it does, the ignition switch is functioning normally; if not, there is a fault before the ignition switch. Check if the wire connections are loose, detached, or corroded. Then, insert the key and turn it to the ignition position without releasing it. Check if the power wire to the starter motor solenoid has electricity. If not, the ignition switch is faulty; if it does, continue checking the solenoid for faults—inspect whether the solenoid coil is open, or if the wires and connections are loose or corroded.
