Is it necessary to replace a deformed inner rim?

The inner rim deformation can be repaired, but replacement is recommended. Here are some details: 1. Rim correction: The stress point of the rim is the spoke. If the spoke is not bent or deformed, it does not affect usage. The deformed rim can be corrected. Rim deformation repair uses a correction machine to adjust the vertical and lateral wobble values within the standard range. 2. Correction method: First, pad the dented area with sponge or cloth, then hammer the dented part flat and apply body filler (putty). Find the roundness on the rim, smooth out uneven areas, and roughen the surface with sandpaper to prepare for painting. Let the putty dry completely, then repaint the entire rim. After drying, a 'new' rim will be reborn. 3. Influencing factors: Rim deformation is caused by driving too fast over potholes. It is advised that car owners take care of their rims, slow down when encountering potholes, and avoid excessive speed in daily driving. If the rim edge is deformed, it is recommended to repair it promptly to avoid affecting usage.

What is the method for checking tire pressure with a tire pressure gauge?

A tire pressure gauge needs to be connected to the tire valve stem to check the car's tire pressure. Below are specific instructions for adjusting car tire pressure: 1. Rough roads: On roads with significant bumps, it is appropriate to reduce the tire pressure by 0.1-0.2bar below the standard tire pressure. For long-distance high-speed driving, the tire pressure should not be too low; it is advisable to increase the tire pressure by about 0.2bar above the lower limit of the standard tire pressure. 2. New and old tires: For new tires, the pressure can be increased by about 0.2bar above the standard tire pressure. For old tires, it is appropriate to reduce the tire pressure according to the standard, and if the wear is severe, adjust to the lower limit of the standard tire pressure. 3. Summer and winter: In winter, it is advisable to increase the tire pressure by about 0.2bar above the standard. In summer, follow the lower limit of the standard tire pressure. If the car is parked outdoors in summer, the pressure can generally be about 0.1bar lower than the standard to avoid tire blowouts due to high temperatures.

What is the best way to clean a three-way catalytic converter?

Here are the methods for cleaning a three-way catalytic converter: 1. Adding a cleaning agent to the fuel tank: This method is very common in the market, with the biggest advantage being its low cost and simple operation. You only need to pour this type of cleaning agent directly into the fuel tank. 2. Drip cleaning: Also known as no-disassembly cleaning, this method for cleaning the three-way catalytic converter has the advantage of not requiring the removal of the catalytic converter. However, the downside is the high cost of purchasing the cleaning equipment, and the cleaning effect is not ideal. 3. Disassembly cleaning: Disassembly cleaning is a very time-consuming and labor-intensive method. It requires completely removing the three-way catalytic converter from the vehicle, soaking it in a cleaning agent (such as oxalic acid or toilet cleaner) for a period of time, and then rinsing it with clean water.

Can an Automatic Transmission License Be Upgraded to a Manual Transmission License?

An automatic transmission license can be upgraded to a manual transmission license. 1. License Types: C1 allows driving both manual and automatic transmission small cars, while C2 only permits driving automatic transmission small cars. General vehicles cannot be driven. 2. Method of License Upgrade: After obtaining a C2 license, if one needs to drive a manual transmission car, they must apply for a C1 license upgrade. The applicant must re-register and pass the C1 license's subject one, two, and three exams to obtain the upgrade. More relevant information is as follows: 1. Manual Transmission is C1: The C1 driver's license permits driving small and micro passenger cars, as well as light, micro cargo vehicles, and small, micro special-purpose vehicles. Among these vehicle types, whether manual or automatic transmission, drivers holding a C1 license can operate them. 2. Automatic Transmission is C2: Manual transmission drivers can save fuel by selecting the appropriate gear. Generally, mechanical transmission cars are considered more fuel-efficient because mechanical transmissions have higher transmission efficiency, reducing transmission losses.

Where is the OBD interface located on the Geely GX7?

The OBD interface of the Geely GX7 is located inside the trim panel below the left side of the dashboard. The OBD system continuously monitors the engine, catalytic converter, particulate filter, oxygen sensors, emission control system, fuel system, EGR, and other components and systems. It then connects to the ECU (Electronic Control Unit) through information related to various emission components, enabling it to detect and analyze faults related to emissions. Below is how the OBD system works: 1. Detecting excessive emissions: The OBD system constantly monitors whether the vehicle's emissions exceed standards during engine operation. If they do, it immediately issues a warning. 2. Fault detection: When a fault occurs in the system, the Malfunction Indicator Lamp (MIL) or Check Engine warning light will illuminate. Simultaneously, the Powertrain Control Module (PCM) stores the fault information in memory, and the fault code can be retrieved from the PCM using a specific procedure. 3. Identifying faults: Based on the fault code, maintenance personnel can quickly and accurately determine the nature and location of the fault.

Can Temporary License Plates Be Captured for Traffic Violations?

Generally, temporary license plates for new vehicles do not contain embedded electronic chips, so they are usually not captured by electronic traffic violation monitoring systems, mainly because the photos are too blurry. Below is relevant information about temporary license plates: 1. Placement: Temporary license plates are issued by the vehicle management office of the public security bureau before the vehicle is officially registered. For new vehicles, temporary license plates can be placed in the lower right corner of the front windshield and the lower left corner of the rear windshield, as long as they do not obstruct the view. They should not be used for more than 15 days, and the owner should promptly apply for official license plates at the vehicle management office. 2. Penalties for temporary license plates: (1) Failure to hang the temporary license plate as required will result in a 12-point deduction. (2) Covering or obscuring the temporary license plate will be penalized the same as covering an official license plate, resulting in a fine and a 12-point deduction. (3) Using an expired temporary license plate will generally result in a fine and a 12-point deduction.
