Coolant flush: when and how to do it?

Essential for proper engine operation, changing the coolant is often neglected by French drivers. However, it’s important to note that when this fluid starts to lose its effectiveness, the car will tend to overheat and the engine will no longer be protected against freezing. When should you change the coolant? Approximately every two years or every 20,000 to 30,000 km, you should consider changing your car’s coolant. In addition to this indicator, if you notice that the engine temperature easily rises above 100°C, it may also be time to replace this fluid. On the other hand, if the coolant was changed less than a year ago and the engine is overheating, there is probably another problem. And to best address this,

the best option is to contact a mechanic because you may have a

problem with the thermal switch, the thermostat, the fan, or the radiator. How do you change the coolant? Even though it’s fairly simple to do, you shouldn’t skip any steps when you’re going to change the

coolant. Coolant change Coolant change First of all, locate the drain plug, which is usually located under the radiator. Then let the coolant drain into

a small basin. This operation should generally take 30 minutes so that

all the old coolant is completely drained. To clean the passages, pour water into the radiator and start the car in neutral for 5 to 10 minutes. After that,

Once the engine has cooled down, gradually pour the coolant into the cooling system* until it reaches the optimal level. * Caution:

It may happen that the antifreeze or coolant you buy needs to be mixed with water. To avoid making a mistake, be sure to read the instruction manual carefully. After that, start the engine again and wait at least

one hour. Then, if you see that the fluid level is correct, the draining is complete. However, if it isn’t, you need to add a little more fluid. But before doing so, always wait until

the engine is cold again.A few days after the draining, be sure to recheck the coolant level. And if it’s too low, don’t hesitate to repeat the process.
