New wipers may fail to reach a section in the middle due to oil film on the windshield. If it's a beam-type wiper, the issue might be insufficient pressure from the wiper arm, preventing the wiper from fully extending. It is recommended to replace the spring strip on the wiper arm or switch to a triple-section wiper. Many car owners neglect proper windshield cleaning during routine car washing and maintenance, leading to dirt and deposits on the windshield that reduce its smoothness. A wiper is a blade structure installed in front of the windshield, consisting of a motor, reducer, four-bar linkage, wiper arm spindle, and wiper blade assembly, primarily used to clear rain, snow, and dust that obstruct visibility on the windshield.

How Long Can a Car Engine Last?

Car engine lifespan is typically calculated based on years of use and mileage, with variations existing among different car engines. Therefore, a high-quality engine can be considered a significant advantage for a vehicle. Currently, the average lifespan of a car engine is around 15 years, but in practice, it can be influenced by many factors. Specific details are as follows: 1. Maintenance: The most critical factor affecting engine lifespan is car maintenance. Even the best hardware can wear out quickly without proper care. Some vehicles are used until scrapped without undergoing major engine repairs, simply because the owner maintained the car meticulously during its usage. 2. Driving Habits: Driving habits also greatly impact the engine. There are many precautions to consider when using a car. Improper usage may not show immediate effects but can gradually cause engine wear and shorten its lifespan. 3. Engine Oil: Engine oil plays a vital role in lubrication, cooling, rust prevention, and wear resistance during car operation. If the oil quality is poor, its lubrication and other functions will be less effective, making the engine more prone to wear during operation.

What are the functions of the braking system?

The functions of the braking system: 1. Ensure that the vehicle can decelerate and stop as required by the driver during driving; 2. Ensure reliable parking of the vehicle; 3. Guarantee the safety of the vehicle and the driver; 4. Maintain stable speed for vehicles driving downhill and keep stationary vehicles from moving. Below is an introduction to the automotive braking system: 1. Definition: The automotive braking system refers to the specialized braking mechanism installed on vehicles to technically ensure safe driving and improve the average speed of the vehicle. Generally, the automotive braking system includes two independent sets of devices: the service braking device and the parking braking device. 2. Malfunction handling: While controlling the direction according to road conditions and speed, quickly downshift. Shift from high gear directly into medium gear, where the engine will generate significant traction resistance to rapidly reduce the vehicle speed. At this point, the hand brake can be used to quickly shift into low gear and the lowest gear, and then the hand brake can be used to bring the vehicle to a complete stop.

Should You Turn on Traction Control When Driving in the Rain?

You should turn on traction control when driving in the rain. Here are some safety tips for driving in rainy conditions: 1. Reduce speed appropriately: Wet and slippery roads reduce tire grip, which can cause the vehicle to lose control when turning or overtaking. Therefore, it is advisable to lower your speed and minimize lane changes or overtaking maneuvers. 2. Fogging inside the car: Rain significantly affects visibility by blurring the rearview mirrors. Additionally, many people roll up their windows to prevent rain from entering the car, which can lead to interior fogging. 3. Vehicle loss of control: Puddles form on the road during rain, and if a wheel suddenly enters a puddle, the resistance increases abruptly, potentially causing the vehicle to skid or lose control. 4. Component checks: If your car's windshield wipers are old and not cleaning properly or if there is sunroof leakage, it is recommended to visit a 4S shop in advance to inspect these components.

Why does the old Mazda 6 use 5w40 engine oil?

Because 5w40 engine oil provides better protection for the engine. Here is relevant information about 5w40 engine oil: 1. In 5w40 engine oil, 'w' stands for winter, indicating it is suitable for winter use. The '5' before the 'w' represents the viscosity at low temperatures, with a smaller number indicating better fluidity and cold resistance. The '40' refers to the viscosity at 100 degrees Celsius, with a higher number indicating greater viscosity and better high-temperature resistance. 2. The functions of engine oil include: reducing friction and high temperatures; cooling and lowering temperature; cleaning; shock absorption; and preventing rust and corrosion. 3. Engine oil, also known as engine lubricant, is composed of base oil and additives. The base oil is the main component of the lubricant, determining its basic properties, while the additives compensate for and improve any deficiencies in the base oil's performance.

What does it mean when a car dashboard displays a key icon?

A key icon displayed on the car dashboard indicates that the vehicle's anti-theft system has been triggered. When the anti-theft system light is on, the following phenomena should be noted: 1. If the anti-theft system light is on and the car fails to start, it means the vehicle cannot be activated. The anti-theft indicator light includes both the factory-installed anti-theft indicator and any aftermarket anti-theft system indicators. The anti-theft indicator has armed and disarmed states, and its flashing frequency varies between these two states. 2. It's important to note that if the engine anti-theft light flashes once every 1 to 2 seconds, this is normal. It indicates that the vehicle's engine has entered the anti-theft mode, and the engine immobilizer is functioning properly. This is a normal condition that doesn't require the owner to deactivate it. Moreover, the power consumption is negligible and poses no problem for the battery.
