Can Tap Water Replace Windshield Washer Fluid?

Tap water cannot replace the function of windshield washer fluid. Because water contains impurities, it can easily clog the washer fluid nozzles. When purchasing windshield washer fluid, avoid low-quality products as they can accelerate wiper blade aging. Additionally, prolonged use of tap water to clean the windshield may increase friction between the windshield and wiper blades, leading to scratches on the glass surface. Moreover, tap water can only remove surface dust and is ineffective against other dirt and insect residues. In summer, you can use concentrated wiper fluid as a substitute. Add the concentrated wiper fluid to water, shake it thoroughly, and then pour it into the vehicle as windshield washer fluid. Windshield washer fluid contains specific cleaning agents that effectively clean the glass, which tap water lacks. Therefore, the proper substitute is concentrated wiper fluid, not tap water. Use dedicated windshield washer fluid in winter: During winter, it is essential to use specialized windshield washer fluid with a low freezing point. Otherwise, the fluid may freeze due to low temperatures. When liquids freeze, their volume expands, which can damage the washer fluid reservoir. Windshield washer fluid offers the following features: Cleaning performance: Windshield washer fluid is formulated with various surfactants and additives. Surfactants typically have wetting, penetrating, and solubilizing functions, effectively removing dirt. Antifreeze performance: The presence of alcohol and ethylene glycol significantly lowers the freezing point of the liquid, preventing freezing and quickly dissolving frost. Anti-fog performance: A single-molecule protective layer forms on the glass surface, preventing fog droplets and ensuring clear visibility. Lubrication performance: The ethylene glycol in the fluid has high viscosity, providing lubrication to reduce friction between wiper blades and the glass, preventing scratches. Anti-corrosion performance: The fluid contains multiple corrosion inhibitors, ensuring it does not corrode any metals, car paint, or rubber, making it completely safe.

What Causes the Steering Wheel to Feel Heavier?

There are several reasons why a car's steering wheel may feel heavier: 1. Insufficient power steering fluid. Power steering fluid is a medium oil used in the car's power steering pump to transmit steering force and provide cushioning. It needs to be replaced regularly, and any leaks should be checked. When the power steering fluid is insufficient, the steering wheel may feel heavy and stiff. 2. Low tire pressure. Low tire pressure increases the contact area between the tires and the road surface, leading to greater friction and making steering more difficult, resulting in a heavy steering wheel, which is not conducive to driving safety. 3. Toe-in issues. Toe-in can also affect the car's steering. Toe-in helps the steering wheels automatically return to the correct position, ensuring stable straight-line driving. Problems in this area can also cause the steering wheel to feel heavy. 4. Malfunction of the steering gear or power steering pump. The steering gear and power steering pump are also critical components affecting the car's steering. Any malfunction in these parts can make steering difficult. Issues such as universal joints, chassis suspension stabilizer bars, or plain bearings should not be overlooked. 5. Overly tight bearing fit. If the rolling bearings or sliding bearings in the steering system are too tightly fitted, it can lead to poor lubrication and cause sticking or resistance.

What Causes the ABS Yellow Light to Illuminate?

There are multiple states of the ABS warning light, each with different causes and solutions: State 1: ABS warning light remains constantly illuminated (most common). Cause 1: The ABS wheel speed sensor's sensing area is covered by dirt, mud, or other contaminants, affecting its ability to detect wheel speed signals. This prevents the ABS control module from determining vehicle speed or wheel slip rate, thus failing to issue appropriate braking commands. Solution: Clean the wheel speed sensor and adjust the gap between the sensor and the tone ring. Cause 2: Loose wiring connections or poor contact in ABS relays causing signal issues. Solution: Inspect and reconnect any loose wiring connections. State 2: ABS warning light intermittently illuminates but turns off during acceleration. Cause: Battery voltage drops below 10.5V when multiple electrical components are in use. The light extinguishes when engine RPM increases and voltage rises. Possible low voltage supply to ABS system due to poor connections. Solution: Check battery specific gravity, charging system, and power supply connections (voltage relay or power contacts). State 3: ABS warning light stays on after engine start until engine is turned off. Cause: Poor ground connection at ABS hydraulic valve body; faulty wiring connections; ABS control module failure. Solution: Loosen and retighten hydraulic valve body ground screw (clean contact surface if necessary); check connector gaps; replace ABS or ABS/ASR control module. State 4: ABS warning light illuminates during high-speed driving. Cause: ABS control module detects significant speed difference between front and rear wheels; incorrect tire or wheel specifications. Solution: Verify correct tire and wheel specifications (refer to fuel filler door sticker). State 5: ABS warning light flashes intermittently. Cause: Improper brake light switch adjustment; internal contact issues in brake lights. Solution: With engine running, depress brake pedal and manually push brake switch linkage downward to reset position; replace brake light switch if needed. When the ABS warning light is on, continued driving is not recommended. ABS malfunction means loss of anti-lock braking function - locked wheels during emergency braking may cause skidding and loss of vehicle control, creating significant safety hazards.

Can a Temporary ID Card Be Used for Subject 2 Driving Test?

A temporary ID card can be used for the Subject 2 driving test. However, if you do not have a regular ID card and need to use a temporary one, you must inform the driving instructor in advance and follow the driving school's arrangements for the test. According to Article 19, Paragraph 1 of the "Regulations on the Application and Use of Motor Vehicle Driving Licenses," "First-time applicants for a motor vehicle driving license shall fill out an application form and submit their identity proof." Therefore, you can take the Subject 2 test with a temporary ID card. One important note: The validity period of a temporary resident ID card is three months. You can take the Subject 2 test within this validity period. If the card expires, you will not be allowed to enter the test site. Thus, it is essential to take the test before the temporary ID expires. If the temporary ID expires due to special circumstances, you should promptly apply for a formal ID card or a new temporary ID. Subject 2, also known as the small road test, is part of the motor vehicle driving license assessment. It refers to the field driving skills test. For small vehicles (C1/C2), the test includes five mandatory items: reverse parking, parallel parking, stopping and starting on a slope, right-angle turns, and curve driving (commonly known as the S-curve). Some regions may also include a sixth item: high-speed toll collection. According to Article 25 of the "Regulations on the Application and Use of Motor Vehicle Driving Licenses" (Ministry of Public Security Order No. 123), as of June 1, 2021, the Subject 2 test for C2 and C5 no longer includes stopping and starting on a slope. For large vehicles (AB licenses), the Subject 2 test covers 16 items: reverse parking, passing continuous obstacles, curve driving, highway simulation test, width-restricted gate, bumpy road, single-plank bridge, narrow road U-turn, stopping and starting on a slope, parallel parking, highway emergency handling, mountain road simulation, right-angle turns, rain and fog weather simulation, highway tire blowout, and tunnel simulation driving.
