Can I add coolant by myself?

[DeGiselle]

You can add coolant by yourself, but it's important to note that you should find the same type of coolant for addition. If the same type is unavailable, at least ensure the color matches. Never mix coolants of different colors. Additionally, pay attention to the freezing point temperature. The coolant you add should have the same or a lower freezing point than the original to prevent the overall freezing point from dropping after multiple additions, which could render it unusable in your region. Points to note when adding coolant: 1. Check the coolant filler port mark carefully; the coolant reservoir cap usually has a symbol resembling a triangular thermometer. 2. Do not use water as a substitute for coolant or mix water with coolant. Water has a higher freezing point and contains impurities that can form scale over time, leading to blockages.
