How to Check the Condition of a Used Car's Transmission?

Check if there is any oil leakage from the transmission oil pan. Start the engine, engage each gear, and observe whether the transmission jerks when shifting gears. Then proceed with a road test to assess whether the gear shifts smoothly and if there are any severe jerks or hesitations. Below is an introduction to the transmission: Composition: The transmission consists of a gear transmission mechanism and a control mechanism, with some vehicles also including a power output mechanism. The transmission mechanism mostly uses ordinary gear transmission, while some employ planetary gear transmission. Ordinary gear transmission mechanisms typically use sliding gears and synchronizers, among others. Function: The transmission is a crucial component in the vehicle's powertrain, serving the purpose of changing speed and torque. Without a transmission, the car cannot operate normally. The transmission is a mechanism used to alter the speed and torque from the engine, capable of fixing or changing the gear ratio between the output and input shafts, hence also referred to as a gearbox.

How Long Can Tesla Dash Cam Footage Be Saved?

Tesla dash cam footage can typically be saved on the memory card for one to two years under normal circumstances. The duration before the footage gets overwritten depends on the dash cam's maximum supported capacity and the size of the memory card. Below is additional information about dash cam memory cards: Common memory card sizes for dash cams in the market: Most dash cams support 32G, with some supporting 64G. The Mingju M2 panoramic dash cam, an industry-first national patent-subsidized product, features a single unit with 4 lenses, dual 1440P resolution, dual WiFi, and dual memory, supporting up to 256G—currently the largest memory capacity supported by any dash cam. Due to technical and cost limitations, most dash cams have capacity restrictions. For example, a dash cam that supports a maximum of 32G will only recognize the first 32G of a 64G card, leaving the remaining capacity unusable. Therefore, using a 64G memory card in a 32G-limited dash cam is wasteful, as it can only utilize 32G or may not recognize the excess capacity at all. How to evaluate the quality of a dash cam: Judge based on the memory usage over time. For a 32G memory card with the current mainstream 1080p resolution (which offers suboptimal quality), approximately 120MB of capacity is needed per minute of recording, amounting to about 7G per hour. For 720P resolution (an outdated and inferior product), about 80MB per minute or 4.7G per hour is required. Many 720 or 1080 products are misleadingly marketed as "high-definition," imitating the superior 1296 or 1440 (currently the highest definition) products. With a 32G memory card, a 1080P configuration can record continuously for about 4.5 hours. If the dash cam has front and rear lenses sharing one memory card (front at 1080P and rear at 720P—720P is currently the highest resolution supported for rear views in China, while the Mingju M2 is the first domestic product to support 1080P for side or rear views), the recording time is approximately 3 hours.

When is the Right Time to Replace Car Tires?

Determine whether to replace by observing the appearance and testing. Below is relevant information about tires: Directly check the production date of the tire: Generally, tires will have a production date marked on them. Once they reach a certain age, it's time to replace them. Some people may not drive much, but if the tires have been in use for seven or eight years, even if the mileage hasn't been reached, the tires still need to be replaced periodically. Check the tire wear indicators: There are some raised points in the grooves of the tire. If the wear on the tire reaches these points, it indicates that the tire needs to be replaced. Continuing to use it beyond this point can be dangerous. Use a coin to check the tire wear: This method is quite simple. Place a coin in the groove where the wear indicator is located. If only a small part of the coin is covered, it means the tire is nearly worn out and it's time for a replacement.

Is it necessary to pay the purchase tax before registering a vehicle?

Purchasing a new vehicle requires paying the purchase tax before registration. For taxable vehicles requiring registration, the tax should be declared and paid to the competent national tax authority at the vehicle registration location. For taxable vehicles not requiring registration, the tax should be declared and paid to the competent national tax authority at the taxpayer's location. The vehicle purchase tax is calculated based on an ad valorem rate, with the formula: Tax Payable = Taxable Price × Tax Rate. If the consumer purchases a domestic private vehicle, the taxable price includes the full payment to the dealer and additional fees, excluding the VAT (17%). Since the purchase price on the special invoice for motor vehicle sales includes VAT, the VAT must be deducted first when calculating the vehicle purchase tax, i.e., Taxable Price for Vehicle Purchase Tax = Invoice Price ÷ 1.17, and then the vehicle purchase tax is calculated at a 10% rate. There are two key points to note regarding the vehicle purchase tax: 1. The vehicle purchase tax has a time limit. Starting from the date of the purchase invoice, the tax must be paid within 60 days. Late payments will incur a daily late fee of 0.05% of the tax amount. 2. After paying the vehicle purchase tax, the tax authority will issue a "Vehicle Purchase Tax Payment Certificate," which the owner must keep safely and does not need to carry in the vehicle. If this certificate is lost, it must be reissued.

Where is the SD card slot for the CT6 dash cam located?

The SD card slot for the Cadillac CT6 dash cam is located on the right side of the rear compartment inside the trunk. The slot in the trunk is for the added streaming media. Below is a brief introduction to the Cadillac CT6: CT6's Rearview Mirror: The Cadillac CT6 was the first to use a technology called streaming media video rearview mirror. This mirror features a TFT-LCD display with a resolution of 1280*240. An external rearview camera captures the view behind the vehicle and feeds it to the interior rearview mirror. The streaming media video rearview mirror can expand the rear visibility range by three times. CT6's Exterior: The Cadillac CT6's exterior draws inspiration from some design concepts of the Elmiraj concept car. It features a flatter, wider, and more layered shield-shaped grille. The headlights have an aggressive design, combined with Cadillac's classic diamond-cut design elements, giving the front a very dynamic appearance. On the side profile, the CT6's body lines are smooth, with two waistlines designed to enhance the visual sportiness. CT6's Body Structure: The Cadillac CT6 is built on the all-new Omega rear-wheel-drive platform. 64% of the body frame is constructed from aluminum alloy materials, reducing the weight by 99 kilograms compared to an all-steel body.

Is It Okay for the Engine Compartment to Have High Temperatures in Summer?

Engines generate a significant amount of heat during operation, so it is normal for the engine compartment to have high temperatures. For turbocharged engines, the temperature inside the engine compartment is also very high. The turbocharger of a turbocharged engine is also located in the engine compartment, and this component generates a lot of heat during operation. Here is some additional information: Vehicle Cooling: Most cars have an exhaust manifold visible after opening the hood, and this exhaust manifold also heats up during operation, which is why the high temperature in the engine compartment is normal. During regular use, if you have just completed a long-distance trip or engaged in spirited driving, you can open the hood to help cool the engine compartment.
