Whether water should be added to windshield washer fluid for cars depends on whether you are in the north or the south. If you are in the north, you can add water because it can prevent the washer fluid from freezing; if you are in the south, you should not add water, as it will reduce the cleaning effectiveness. Windshield washer fluid, commonly known as car windshield cleaning fluid, is a consumable in car maintenance. High-quality windshield washer fluid is mainly composed of water, alcohol, ethylene glycol, corrosion inhibitors, and various surfactants. Car windshield washer fluid is widely used for quick dirt removal and bright cleaning of car windshields, rearview mirrors, home glass, office glass, door and window glass, and decorative glass. It is versatile, easy to use, and can even be homemade.

Must spark plugs be replaced at a 4S shop?

Spark plugs do not necessarily need to be replaced at a 4S shop. Here is the method for replacing spark plugs: 1. After the engine has completely cooled, unplug the high-voltage coil connector, then use a 10mm socket to remove the fixing bolts. Once the high-voltage coil is removed, you can see the spark plug in the cylinder. 2. Depending on the size of the spark plug nut, use a 14mm or 16mm socket with a long extension to turn counterclockwise and loosen it. After loosening, use a magnetic rod to pull out the spark plug. 3. After removing the spark plug, if you cannot install the new spark plug immediately, reinsert the high-voltage coil or use a clean cloth to cover the spark plug hole to prevent dirt from falling in. 4. Use the magnetic rod to hold the new spark plug and insert it into the hole, then tighten it. Note that the torque for installing the spark plug should not be too high, approximately 20 Nm. 5. After replacing all the spark plugs, start the engine to check if the spark plugs are working properly.

Which Cars Can Be Equipped with Run-Flat Tires?

Run-flat tires must be installed on dedicated rims to prevent them from falling off the rims in a zero-pressure state. Therefore, ordinary rims cannot accommodate run-flat tires. Models like the Volvo S60 and Volkswagen R36 are equipped with run-flat tires. Currently, all BMW models come standard with run-flat tires, while other models such as the Volvo S60, Ford S-MAX, and Volkswagen R36 also feature run-flat tires. Run-flat tires, also known as self-supporting tires or extended mobility tires, work by thickening the sidewalls. Even when deflated, the thick sidewalls provide necessary support to keep the vehicle moving. If a car originally comes with standard tires, run-flat tires cannot be used. Using run-flat tires on a car not originally designed for them can cause damage to the matching chassis, suspension, and rims.
