What concentration should my coolant be?
What concentration should my coolant be? A reading from 33 to 50 percent is normal. Anything more or less means you need to add either antifreeze or water to bring the concentration within a normal range. What is the recommended ratio percentage of coolant to water in my cooling system? The mixing ratio of water and antifreeze should lie between 60:40 and 50:50. This usually corresponds to antifreeze protection from -25°C to -40°C. The minimal mixing ratio should be 70:30 and the maximal 40:60. Is concentrated coolant better than 50 50? Most manufacturers recommend a 50/50 mix of antifreeze concentrate...
