Winter windshield washer fluid may fail to spray due to the following reasons: 1. The added washer fluid has insufficient antifreeze capability. 2. The windshield nozzle is clogged. 3. The washer pump is damaged or there is a wiring issue. 4. Leakage in the washer fluid pipeline. 5. Insufficient washer fluid level. Below are the functions of windshield washer fluid: 1. Cleaning performance: Windshield washer fluid is formulated with various surfactants and additives. Surfactants typically have functions such as wetting, penetrating, and solubilizing, thereby achieving cleaning and stain removal. 2. Antifreeze performance: The presence of alcohol and ethylene glycol in the washer fluid can significantly lower the freezing point of the liquid, thus providing antifreeze effects and quickly dissolving frost. 3. Anti-fog performance: The washer fluid forms a single-molecule protective layer on the glass surface. This protective film prevents the formation of fog droplets, ensuring the windshield remains clear and transparent with a clear view. 4. Anti-static performance: After cleaning with washer fluid, substances adsorbed on the glass surface can eliminate static charges on the glass, providing anti-static properties. 5. Lubrication performance: The washer fluid contains ethylene glycol, which has a high viscosity and can provide lubrication, reducing friction between the wiper and the glass to prevent scratches. 6. Anti-corrosion performance: The washer fluid contains various corrosion inhibitors that have no corrosive effect on any metals, ensuring absolute safety for automotive paint and rubber.

How Often Should a Car Undergo Major Maintenance?

Generally, a car should undergo major maintenance every 20,000 kilometers. For 6-cylinder cars, it's recommended every 2 years or 60,000 kilometers, while 4-cylinder cars should have it every 2 years or 80,000 kilometers. Regular car maintenance includes changing the engine oil and oil filter, frequent car washing, and regular checks on tire surface and pressure, oil level, coolant level, and brake fluid level. Major maintenance covers a wide range of services such as engine oil, three filters (air, fuel, and oil), transmission gear oil, coolant, brake fluid, power steering fluid, spark plugs, throttle body cleaning, fuel injector cleaning, catalytic converter cleaning, tire rotation, brake pad inspection and replacement, inspection of all rubber hoses, checking all lights, and tightening all screws.

Can You Turn Right at a Red Light Intersection?

You can turn right at a red light intersection. Traffic lights can be categorized as follows: 1. If there is a red light "No Right Turn" sign before entering the intersection, then you cannot turn right, otherwise it will be a violation; 2. If there is no sign and it is a circular red light, then you can turn right without it being a violation; 3. If there is a right-turn arrow signal and the right-turn arrow is red, you cannot turn right, otherwise it will be a violation. When the circular light is red, yellow, or green, it respectively indicates that straight-going vehicles are prohibited, warned, or permitted to proceed. When the left-turn arrow light is red or green, it respectively indicates that left-turning vehicles are prohibited or permitted to proceed. Right-turning vehicles, provided they do not hinder the passage of released vehicles or pedestrians, may proceed without being regulated by the traffic signal, at an appropriate time.

What are the reasons for the Aoling engine malfunction indicator light coming on?

Sensor issues, engine misfire, vehicle maintenance problems, fuel quality issues, poor combustion of the air-fuel mixture, engine intake problems, turbocharging issues, exhaust problems, and anti-theft system malfunctions are all primary reasons for the engine malfunction indicator light to illuminate. Additionally, during vehicle startup, the system performs a self-check on the engine. Normally, the malfunction light should turn off after the self-check is completed. If it remains on for an extended period, it is advisable to visit a repair station promptly for professional assistance to diagnose and eliminate potential safety hazards. Below is a detailed explanation of each potential issue: Sensor Issues: Sensors such as coolant temperature, crankshaft position, air flow, intake temperature, and oxygen sensors can cause the engine malfunction light to illuminate if they are damaged, have poor connections, or experience signal interruptions. This prevents the ECU from accurately obtaining engine data. Solution: Seek professional inspection at a repair center to promptly address safety concerns. Maintenance Issues: Poor engine maintenance is one of the most common reasons for the malfunction light to come on. Vehicles have specific maintenance schedules, and failing to adhere to them, combined with poor driving habits, can increase the engine's operational burden, eventually triggering the malfunction light. Solution: Follow the maintenance schedule in the vehicle's manual, including time or mileage intervals, to ensure comprehensive maintenance and eliminate non-maintenance-related issues. Fuel Quality Issues: This refers to both fuel and engine oil. Vehicles require specific fuel grades and types of oil (semi-synthetic or full synthetic). If the wrong fuel or oil is used over time, it can lead to engine wear and trigger the malfunction light. Solution: Use the recommended fuel grade and appropriate engine oil for the vehicle. Poor Combustion of Air-Fuel Mixture: Issues such as faulty spark plugs, fuel pump malfunctions, or clogged fuel lines can lead to poor combustion. This results in engine carbon buildup or knocking, which the oxygen sensors detect and report to the ECU, triggering the malfunction light. Solution: Inspect ignition coils and spark plugs; check the performance of related sensors (e.g., oxygen sensors, coolant temperature sensor, intake temperature sensor, throttle position sensor, air flow meter, intake manifold pressure sensor). Also, inspect the air filter for contamination and clean or replace it as needed. Check for fuel injector leaks and the performance of the fuel pressure regulator. Professional inspection at a 4S shop is recommended. Intake Issues: Proper combustion requires adequate airflow, making the air filter crucial. A dirty or clogged air filter can restrict airflow, potentially leading to engine issues and the malfunction light. Solution: Regularly clean or replace the air filter to ensure proper intake system function. Turbocharging Issues: Problems with the intake boost system or turbocharger can trigger the malfunction light. Common issues include turbocharger damage, accompanied by symptoms like oil leaks, excessive oil consumption, reduced power, metallic noises, or blue/black exhaust smoke. Solution: Visit a 4S shop for inspection and replacement of the turbocharger. Repair is often less cost-effective than replacement. Exhaust Issues: The rear oxygen sensor, catalytic converter, and exhaust camshaft and bearings can cause the malfunction light to come on. The catalytic converter is particularly prone to damage from impacts or fuel system issues. Solution: Use lead- or silicon-based lubricants for catalytic converter maintenance and cleaning. Anti-Theft System: If the vehicle's anti-theft system malfunctions or the anti-theft controller is incompatible with the engine ECU, the engine may not operate correctly, and the malfunction light will illuminate. Solution: Seek professional assistance at a repair shop for a systematic diagnosis, as personal repairs are not recommended.
