Car coolant should be changed every 2 years or 40,000 kilometers. The full name of coolant is antifreeze coolant, which means coolant with antifreeze function. It can prevent the coolant from freezing and cracking the radiator and freezing the engine when parking in cold winter. Cylinder block or cover. Coolant is mainly used in liquid-cooled engine cooling systems and has excellent properties such as anti-freeze in winter, anti-boiling in summer, anti-scaling and anti-corrosion all year round. The function of coolant is: 1. Provide anti-corrosion protection to the components of the cooling system; 2. Prevent scale and reduce the heat dissipation of the radiator; 3. Ensure that the engine can operate within the normal temperature range. Antifreeze must have the characteristics of anti-freeze, anti-boiling, anti-corrosion, anti-scaling, and no foam, and is not affected by seasons and regions.

Revving an engine while driving involves briefly increasing the engine speed without significantly accelerating the vehicle. This is often done for performance testing or to clear out carbon buildup. In a manual transmission, you can press the clutch pedal and briefly rev the engine before releasing the clutch smoothly. In an automatic, shifting to neutral before revving is possible but not recommended due to safety concerns and potential transmission damage. Always ensure your actions do not compromise vehicle control or safety. Additionally, excessive revving can lead to unnecessary engine wear, so use this technique sparingly and wisely. Always prioritize the health of your vehicle and adhere to driving regulations.
