How to Determine Wear on a Jetta Synchronizer?

When the Jetta synchronizer is worn, shifting gears becomes difficult, which can be used as an indicator. The working principle of a synchronizer is: during gear shifting, the gear on the power output side rotates faster than the gear that is about to be engaged. It is a mechanical device that resolves the inconsistency between engine speed and transmission speed during gear shifting operations. The following are the differences between transmissions with and without synchronizers: 1. Transmission with synchronizer: When starting and shifting gears, a transmission with a synchronizer does not require waiting for the transmission to adjust speed before directly engaging the gear; 2. Transmission without synchronizer: When starting and shifting gears, a transmission without a synchronizer requires waiting for the transmission to adjust speed before the gear can be engaged.

What Happens If You Don't Slow Down When Going Over Speed Bumps?

The effects of not slowing down when going over speed bumps are introduced as follows: 1. Impact on tires: Tires are the only components of a car that come into contact with the ground, and any changes on the road surface will first affect them. Tires are wear-prone parts, and the driving conditions of the car directly affect their service life. Frequently passing over speed bumps at high speed may damage the tire surface and even cause the wheel rim to be squeezed and deformed. 2. Impact on the suspension: When a vehicle passes over a speed bump at high speed, the suspension system will be subjected to an impact several times or even more than ten times greater than during normal driving, severely affecting the service life of components such as shock absorbers, springs, and brackets. The strong impact can also damage the chassis, posing a threat to the brake lines, fuel tank, oil pipes, exhaust system, and engine oil pan located under the car. This threat is directly related to the driving safety of the vehicle.

Does the Electronic Parking Brake Act on the Front or Rear Wheels?

Electronic parking brakes act on the rear wheels. Here is more information about electronic parking brakes: 1. The electronic parking brake is a technology that achieves parking braking through electronic control. Its working principle is the same as that of a mechanical handbrake, both of which use the friction generated between the brake disc and brake pads to control parking braking. The only difference is that the control method has changed from the previous mechanical handbrake lever to an electronic button. 2. The electronic parking brake has evolved from the basic parking function to an automatic parking function. The application of the automatic parking function technology allows drivers to avoid prolonged braking when the vehicle is stopped. When the automatic electronic parking brake is activated, it can prevent unnecessary vehicle sliding.

Is It Useful to Only Discuss the On-the-Road Price When Buying a Car?

It is useful to only discuss the on-the-road price when buying a car. The on-the-road price truly reflects the actual cost of purchasing a car, so it is ultimately the price to focus on. However, the on-the-road price includes the ex-factory price, so generally, the ex-factory price is negotiated first. Only after determining the ex-factory price can the on-the-road price be known. Additionally, there are too many variable factors in the on-the-road price, and only after settling the ex-factory price can one clearly understand whether other charges are reasonable. Below are the differences between the ex-factory price and the on-the-road price: 1. The ex-factory price can be understood as the actual market price of the vehicle. 2. The on-the-road price refers to the total cost of purchasing a car, which includes not only the ex-factory price but also purchase tax, insurance fees, registration fees, vehicle decoration fees, financial service fees, loan interest, etc.

What Issues Should Be Noted for a New Car?

Before driving, it is necessary to warm up the engine, and the lubrication time should be at least one minute or more. Other precautions: 1. Avoid emergency braking: Emergency braking not only impacts the braking system during the break-in period but also increases the load on the chassis and engine. 2. Avoid overloading: Running a new car at full load during the break-in period can cause damage to the components. 3. Avoid high-speed driving: There should be speed limits, and pay attention to the engine tachometer and speedometer while driving. 4. Avoid changing the oil too early: The initial oil in a car is a special lubricant for the break-in period, which requires low viscosity, good heat dissipation, excellent cleaning, and antioxidant properties. Change the oil according to the manufacturer's specified time.

Where is the cabin air filter of Dongfeng Fengshen S30 located?

Dongfeng Fengshen S30's cabin air filter is located beneath the glove compartment on the passenger side. There is a soft panel in that area, with three self-tapping screws on the innermost side towards the seat direction. After removing these screws, gently pry open the cover panel downwards. By inserting your head inside and looking upwards, you can see the cabin air filter. The technical name for the cabin air filter is "automobile cabin air cleaner," which is a specialized filter used for air purification inside the vehicle cabin. The functions of the cabin air filter are as follows: 1. The most important function of the cabin air filter is to filter out dust from the air, preventing dust from entering the evaporator and forming sludge that could clog it. If there is a noticeable reduction in the airflow from the vents, it indicates a blockage. 2. Another function is air purification. The cabin air filter typically contains activated carbon, which can absorb some harmful gases from the air. It is advisable to replace the cabin air filter regularly for the benefit of human health.
