Can Coolants of Different Colors Be Mixed Together?

[Pedro]

Coolants of different colors cannot be mixed together, and even coolants of the same color may not necessarily be compatible. It depends on the brand and model. It is best not to mix coolants from different brands or models to avoid rendering the coolant ineffective due to differing chemical compositions. How to Choose Coolant: The basic indicators of coolant are its freezing point and boiling point. On the market, coolants come in several specifications with freezing points of -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 area. 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 caused by excessively high cylinder temperatures. Check the coolant reservoir. If the fluid level is below the minimum mark (MIN), do not continue driving and add coolant promptly. Check the water level scale on the coolant tank. The normal coolant level should be between the maximum and minimum marks. To determine if the coolant is low, check the scale. If the coolant is below the minimum mark, it indicates a deficiency.
