Where Can I Buy Car Windshield Washer Fluid?

Car windshield washer fluid is available at supermarkets, gas stations, 4S stores, car beauty shops, or auto parts markets. Below is a detailed introduction to car windshield washer fluid: 1. Cleaning performance. Windshield washer fluid is formulated with a variety of surfactants and additives. Surfactants typically have functions such as wetting, penetrating, and solubilizing, thereby achieving the effect of cleaning and removing dirt. 2. Antifreeze performance. It can significantly lower the freezing point of the liquid, thus providing antifreeze effects and quickly dissolving frost. 3. Anti-fog performance. A single-molecule protective layer forms 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 windshield washer fluid, substances adsorbed on the glass surface can eliminate surface charges, providing anti-static properties. 5. Lubrication performance. With higher viscosity, it can act as a lubricant, reducing friction between the wiper and the glass to prevent scratches.

Why does the engine idle normally but misfire at high speed?

The reasons for normal engine idle but misfire at high speed are as follows: 1. Excessive spark plug electrode gap; 2. Improper adjustment of distributor contact gap; 3. Weak contact arm spring; 4. Faulty ignition coil or capacitor. The solutions for engine misfire at high speed are as follows: 1. Open the distributor cover and check the distributor gap, which should be 0.35-0.45 mm. Otherwise, adjust the contact gap. 2. Check the spring tension of the contacts. Use a spring scale to lift the contacts to the normal gap, and the reading on the spring scale indicates the spring tension. The normal value should be 500-700 grams. If a spring scale is not available, replace a set of contacts. 3. Remove the spark plug and observe the spark plug gap. The normal value should be 0.6-0.8 mm. If a specialized measuring feeler gauge is not available, a hacksaw blade with a thickness of 0.7 mm can be used for testing. This type of fault can be easily detected using an oscilloscope in a professional repair shop.

Where should the temporary license plate be affixed on the car?

Temporary license plates should be affixed as follows: 1. One should be placed on the lower left or right corner of the front windshield inside the car; 2. The other should be placed on the lower left corner of the rear windshield inside the car. Below is relevant information about affixing items on motor vehicles: 1. Motor vehicle license plates should be hung at designated positions on the front and rear of the vehicle, maintaining clarity and completeness. Heavy-duty and medium-duty trucks and their trailers, as well as tractors and their trailers, should have enlarged license plate numbers painted on the rear of the body or cargo compartment, with the characters upright and clearly visible. 2. The motor vehicle inspection compliance mark and insurance mark should be affixed to the upper right corner of the front windshield. 3. Any painting, affixing of marks, or body advertisements on motor vehicles must not affect safe driving.

What to Do About Rattling Noises from the Car Dashboard?

Solutions for rattling noises from the car dashboard are as follows: 1. First, drive slowly and listen carefully to identify the source of the noise. Check for any foreign objects in the dashboard gaps or surrounding areas, such as panels or padding. If the noise persists after cleaning, it is likely due to loose components from frequent use or improper installation during modifications. 2. If screws were not tightened properly during audio system modifications, gaps between panels can be filled with silicone. Also, check if the plastic ducts connected to the air vent adjustment mechanism have cracked due to thermal changes. Additionally, the air ducts connected to the vents on either side of the CD player, located inside the dashboard, can also be sources of noise. 3. Tighten all potentially loose parts thoroughly and clean the dashboard. If the noise comes from the seams around the air vents, use a flathead screwdriver to remove the screws, take out the vents, and secure them with foam double-sided tape. After reattaching, shake the panel to ensure it is properly fixed.

What happens when a car runs out of oil?

When a car runs out of oil, the lubrication effect becomes very poor, and the lack of lubrication can cause the engine to seize. The less oil there is, the more severe the consequences. Hazards of running out of oil: Running out of oil is highly detrimental to the car. When driving with insufficient oil, gasoline cannot cover the oil pump, preventing it from being effectively cooled. This can shorten the oil pump's lifespan, and in severe cases, may directly damage the oil pump. Function of engine oil: The main function of engine oil is to provide proper lubrication for the engine's pistons, bearings, and other components, preventing high-temperature and high-pressure gases in the combustion chamber from leaking into the crankcase through the gap between the piston and cylinder.

How Many Kilometers Before a Major Maintenance is Needed?

Generally, vehicles require a major maintenance service after traveling 30,000 kilometers. The major maintenance items include the following: 1. Replace engine oil, oil filter, fuel filter, and air filter; 2. Inspect the braking system for any oil leaks and check if the brake pads are within the specified thickness; 3. Check the wear condition of the engine belt and adjust the belt tension if necessary; 4. Inspect the transmission, drive shaft, and universal joint boot for oil leaks or damage; 5. Check the tread depth, tire pressure, and wear condition of the tires, and perform a wheel alignment if necessary; 6. Inspect the throttle body and idle valve for excessive dirt and clean them if needed; 7. Check the condition of the spark plugs and replace them if necessary, along with a no-disassembly cleaning of the fuel injectors; 8. Inspect the power steering, braking system, and automatic transmission; 9. Test whether the braking force, gear shifting, and steering are functioning normally; 10. Lubricate all relevant parts of the vehicle.
