Should I Replace the Mixed Red and Green Coolant?
1 Answers
After mixing red and green coolants, replacement is necessary. Coolants of different colors may vary in chemical properties and compositions. Even if their primary ingredients are the same, their secondary components and formulation ratios differ. Mixing them can trigger chemical reactions, leading to hazards such as sedimentation, scaling, and corrosion, which may compromise the engine's lifespan. How to choose coolant: The fundamental indicators of coolant are its freezing and boiling points. Market-available coolants come in various freezing point specifications, such as -15°C, -25°C, -30°C, and -40°C. Generally, it's advisable to select 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 likely indicates low coolant levels, though it could also be due to excessively high cylinder temperatures. Check the coolant reservoir. If the fluid level is below the minimum mark (MIN), do not continue driving and promptly add coolant. Inspect the water level markings on the coolant overflow tank. The normal coolant level should be between the maximum and minimum marks. To check if coolant is low, refer to these marks. If the coolant is below the minimum level, it indicates a deficiency.
