Hello everyone, a month ago I updated my entire cooling system, radiator, hoses, thermostat and before changing it I cleaned it with a lot of gallons of distillate and thermocure. The issue is that since I refilled with coolant and I noticed that the overflow tank does not oxidize, that is, the liquid does not expand and before doing this process it always increased about one or two inches above the full mark when driving it. and when it cooled down it went back down to the full mark, now even after driving a lot it stays at full, sometimes it goes up a few centimeters but it is not changing, there are no leaks under the car I tested 3 radiator caps in case that was the problem and it is also ruled out. Has anyone experienced this before?
Overflow tank question

I would verify the radiator overflow connection and hose do not have obstructions.
I cleaned the tank before installing it and changed the hose since the previous one was very loose. I also made sure to blow to make sure there was nothing obstructing the way. Also, if I uncover the radiator and tighten the upper hose and the coolant exceeds the hole in the conduit, it is seen that there is movement of coolant in the tank, meaning that the connection is not obstructed.
