ENGINE WATER DECREASE

I noticed that there was no water left in the car, then I filled it, looked, there was a slight decrease. I do not understand what this is normal. I do not understand what the temperature is. It is not a problem.

It started in my car too strangely, I had a friend who opened a title on the subject, if you want a review. I changed the Triger set and the circulation. They said, if the meat decreases again, let's look again, and if it is recirculating, we will change it again.You can also have a recirculation problem. is not always always leaking under pressure. If you find the solution, get well done.

very likely to be a radiator
