Toyota Vios can use H4 bulbs with 50 watts. Bulb replacement steps: First open the front hood, remove the original high beam assembly; After cutting open the lamp cover opening, first secure it with adhesive; Open the lamp cover; Install the lamp cover; After adjusting the lights, heat-seal the headlight again to prevent water ingress; Solder the wiring; Complete the installation. Light usage precautions: Use low beams on urban roads with street lights, and switch to high beams when driving on unlit roads or highways. When meeting another vehicle, switch from high beams to low beams. Turn signals should be activated when the vehicle needs to turn. It's important to note that turn signals should be activated approximately 30 to 100 meters before reaching the turning intersection, not just when already at the intersection, to avoid causing rear-end collisions by surprising following vehicles.

Will Crystal Coating Damage Car Paint?

Crystal coating may or may not damage car paint depending on the situation: For vehicles with scratches, the polishing step required during crystal coating application can harm the paint; For new cars or scratch-free vehicles, the mirror restoration process involved in crystal coating application is harmless to the paint. Crystal coating provides reliable paint sealing technology that offers efficient and long-lasting protection for car paint, preventing environmental factors from affecting the paint color. Automotive paint crystal coating is a concept developed to differentiate from waxing and glazing treatments. The fundamental requirement of crystal coating is that it uses SiO2 inorganic materials which form a molecular-level nanostructure on the applied surface. Through the action of high molecular polymers, it creates a protective layer with functions including UV resistance, oil resistance, low surface energy, and hydrophobicity, thereby safeguarding the paint surface.

What Causes White Smoke from the Tailpipe?

The reasons for white smoke from the tailpipe are: 1. The engine is burning coolant, which may be due to cracks in the cylinder block or cylinder head gasket. If this occurs, the cylinder block and gasket should be inspected. If cracks are found in the cylinder block, it should be replaced. 2. The engine block temperature is too low. When the engine warms up, the white smoke will gradually disappear, which is normal. Coolant needs to be replaced regularly. If not changed for a long time, the coolant's freezing point may rise and boiling point may drop. Failure to replace the coolant regularly can affect the engine's normal operation.

Can I Add a Little Water to Antifreeze?

Adding a little water to antifreeze is acceptable, but using water as a substitute for antifreeze can easily cause scale formation in the engine cooling system, which may clog pipes and affect the normal operation and lifespan of the car engine. Additionally, adding too much water to antifreeze can lead to engine overheating. Therefore, it is recommended not to add water. Generally, antifreeze is composed of a mixture of water and concentrate. When antifreeze is insufficient, you can add an appropriate amount of water, but avoid using tap water—use soft water or distilled water instead. It is important not to add too much water, as this can alter the freezing point of the antifreeze. Antifreeze prevents the coolant from freezing during cold winter stops, which could otherwise crack the radiator and damage the engine block. Its full name is antifreeze coolant.
