Can Coolants with Different Freezing Points from the Same Brand Be Mixed?

[AxelLee]

Coolants with different freezing points from the same brand can be mixed. However, different brands of coolants may have varying production formulas. Mixing them may cause chemical reactions among the additives, leading to their ineffectiveness. How to Choose a Coolant: The basic indicators of a coolant are its freezing point and boiling point. Coolants available in the market come with freezing points such as -15°C, -25°C, -30°C, -40°C, etc. Generally, it is advisable to choose a coolant with a freezing point at least 10°C lower than the lowest temperature in your region. How to Determine If Coolant Is Low: Observe the coolant warning light on the dashboard. If it lights up, it is likely due to low coolant levels, though it could also be triggered by excessively high engine temperature. Check the coolant reservoir. If the fluid level is below the minimum mark (MIN), do not continue driving and promptly add coolant. Check the water level indicator on the coolant tank. The normal coolant level should be between the maximum and minimum marks. If the coolant is below the minimum mark, it indicates a shortage.
