Does Rainwater Affect Cars?

Should I Replace Just the Wiper Blade or the Entire Wiper?

For wipers, you only need to replace the rubber blade. The original wiper frame is quite sturdy, so you can just replace the blade without changing the entire set. In most cases, the wiper rubber should be replaced every six months to a year, but this depends on the actual usage of the wipers. If the wiper blade is not replaced for a long time, the aging blade can slightly affect the wiper frame, causing it to age as well. To minimize the impact on the wiper frame, it is essential to replace the blade promptly when needed. Wiper maintenance tips: When using the wiper to remove dust from the windshield on sunny days, always spray windshield washer fluid—never operate the wiper dry. For stubborn or hard dirt on the glass, clean it manually. These substances can easily damage the wiper blade, leading to poor cleaning performance or even affecting the wiper motor in severe cases. When lifting the wiper blade for car washing or routine cleaning, hold the "back" of the blade and gently return it to its position—avoid snapping it back. In winter, use an ice scraper to clear ice chunks from the windshield before using the wiper to reduce the burden on the wiper. Wipers can generally be divided into two types: traditional intermittent wipers and rain-sensing wipers. Rain-sensing wipers are mostly used in mid-to-high-end models. A good wiper should be heat-resistant, cold-resistant, acid- and alkali-resistant, corrosion-resistant, fit the windshield well, reduce motor load, operate quietly, have strong water repellency, and be soft enough not to scratch the windshield—all to ensure clear visibility. How to replace a wiper blade: First, lift the wiper, then detach it from the metal arm. Use a small metal hook to grip the original blade for stability. Pry up the metal hook and pull out the old wiper blade. Remove the plastic cap on one side of the wiper, insert the new blade, reattach the plastic cap, and clamp the metal hook to secure the new blade in place.

What is the C-class for small car driving licenses?

Household small cars generally require either a C1 or C2 driving license. Both refer to vehicles with a total mass not exceeding 4.5 tons, seating capacity (including the driver) not exceeding 9 people, or a vehicle length under 6 meters. The vehicle types permitted by a C1 license include small cars (both manual and automatic transmission). The vehicle types permitted by a C2 license are small automatic transmission cars. Below is the application process for C1/C2 small car driving licenses: 1. Bring the original and a copy of your ID card to the driving school registration point to enroll, and wait for the arrangement of theoretical study time (non-local students need a temporary residence permit, which the driving school can handle on their behalf); 2. Undergo a physical examination, which includes passing tests for ECG, blood pressure, height, weight, hearing, grip strength, back strength, vision, and color vision; 3. Pass the exams (all four subjects must be passed). 4. Collect the driving license by presenting your ID card at the registration point.

What Causes Steering Wheel Vibration When the Vehicle Exceeds 120 km/h?

This is caused by an issue with the wheel balance of the car. A car's wheel is an assembly consisting of the tire and the rim. However, due to manufacturing tolerances, the mass distribution of this assembly may not be perfectly uniform. When the car's wheels rotate at high speeds, this can lead to dynamic imbalance, resulting in wheel vibration and steering wheel shaking during driving. The primary cause of steering wheel vibration at high speeds lies in the wheels, and there are five possible wheel-related factors: 1. Uneven tire pressure among the four wheels (especially the front two). 2. Uneven tread wear on the four wheels (one-sided tire wear). 3. The rims of the four wheels are not perfectly round (steel or aluminum rims deformed into an oval shape). 4. No alignment correction was performed after replacing the four wheels' tires. 5. One of the tires has been punctured by a foreign object, creating a bulge on the tread. This may not be noticeable at low speeds (absorbed by the suspension system), but once the car reaches high speeds, the resulting frequency vibration becomes very apparent. Inspecting the tires can help identify the issue.

What does the red indicator for car water temperature mean?

When the car's water temperature gauge displays a red indicator, it signifies that the engine is overheating. This issue is commonly caused by insufficient coolant in the radiator or a malfunctioning sensor, and immediate inspection is required. Overheating can severely impact the engine, potentially leading to cylinder scoring and significant wear on internal components. Below are related details: 1. When encountering high water temperature, the first step is to check if there is a lack of coolant. If coolant levels are adequate, the issue may stem from a clogged water channel or radiator, a malfunctioning water pump, or a faulty electronic fan system. 2. A defective thermostat can also cause overheating. If the thermostat fails to open properly during engine operation, it restricts the flow of coolant within the engine, leading to elevated water temperature.

What is the best time for the first maintenance of a new car?

New cars should undergo their first maintenance within 3 to 5 months, with the first maintenance mileage typically ranging from 3,000 to 5,000 kilometers, whichever comes first. The specific time can be checked in the vehicle manual. Here is some information about the first maintenance of a car: 1. Different brands and models of cars are equipped with different engines. Some engines use special technology and have strict requirements for engine oil, while others are made of special materials with high precision, resulting in relatively less wear. Therefore, the regulations for the first maintenance time and mileage vary. 2. The first maintenance of a car mainly involves replacing the engine oil and oil filter. It is important to note that when changing the engine oil, the oil filter must also be replaced simultaneously. If the oil filter is not replaced, the new engine oil will be contaminated by the old oil filter.

What are the four alignments?

The four front wheel alignments include caster angle, kingpin inclination angle, camber angle, and toe-in. Below are the specific details of wheel alignment: 1. Function of wheel alignment: Wheel alignment ensures that the tires and the vehicle body maintain the optimal angle, reducing wear between the tires and steering components during driving, ensuring a tight connection between the tires and the ground, and allowing the vehicle to maintain stable straight-line driving. 2. Precautions for tire repair: Tire repair does not require wheel alignment, only wheel balancing is needed. Performing wheel alignment after tire repair can easily disrupt the balance of the vehicle's suspension.
