Does coolant need any additives?

Coolant does not require any additives. Below is an introduction to automotive coolant and selecting the correct coolant specification: Automotive coolant: The "coolant" in a vehicle refers to antifreeze (coolant). The coolant reservoir will have this label, and the dashboard may also display an indicator light. Some models may show a "LOWCOOLANT" warning light, indicating that the coolant level is too low and needs to be refilled. Selecting the correct coolant specification: When refilling coolant, the correct specification should be used, and mixing different types should be avoided. Do not remove the engine coolant reservoir cap, intercooler coolant reservoir cap, or radiator cap when the engine is hot. The cooling system may be under pressure, and removing the cap could cause hot coolant to spray out, leading to severe burns or other serious injuries.
I've been driving for over 20 years, and if the coolant level is low, it definitely needs to be topped up promptly. Most of the time, you should add a mixture of distilled water and specialized coolant, ideally in a 50/50 ratio of water to coolant. Never use tap water or river water, as this can cause engine rust, freezing, or overheating. When checking the coolant reservoir, always do so when the engine is cold, and if the level is low, top it up to the 'max' mark. When buying coolant, pay attention to your vehicle's requirements and the specified color—never mix different types, such as silicate and organic acid coolants, as this can cause issues. Regular coolant replacement is also crucial, typically every two years or 40,000 kilometers. My car gets regular maintenance to avoid overheating problems. Breaking down on the road is no fun, so it's always better to be cautious.
