Do you think the movement indicator level is normal?

The problem now is: I made a road trip today. The road I am talking about the ring road goes down to 80 degrees or even 79 degrees. It remained constant there. Anyway, I closed the car, I saw my job, some lights on the way back, and the traffic passed 100s. I went up to the ring road this time, normally between 85-89. I do not understand this situation. Why the thermostat has changed sometimes stays in the 80s, while at some time 89 stops when it should be normal. Shouldn't it always be in the 89s? I would like to receive your comments, do you perceive a problem? Is there any situation that you can say is this? Because if the car does not come to its proper temperature, it will burn more fuel and I will do whatever I can to make my car burn less.

This is in the picture. :

I think I'm wearing it very much. The nation complains of height. But on the other hand, I live in Izmir, yet the weather is fine. Wouldn't it be a problem if the weather doesn't even reach the 80s when it gets colder now? Or the colder it falls below 80 I can not predict it. I have no problems in heating heating, I also mentioned that I heated up in 5 minutes, the engine makes the interior of the car like a flame.

The thermostat keeps the engine temperature constant at 89 degrees. I knew it would open when it exceeds 89 degrees and allow cold water to enter. That's why I changed the thermostat and started to feel faint because the engine was traveling in the 80's. In fact, I opened the subject thinking that as soon as the thermostat breaks down. I am learning the work by taking your thoughts ..

This is what I wondered about what is the situation in your vehicles. It's a normal situation then. Thanks

I wrote it for a long time, thanks you have read it. As you said, the weather is cool right now, while the wind goes on the ring road, the temperature against the wind traveled around 85-90 in the turn. That is the situation in our vehicles in general. As you said at 100 degrees, I have not seen the maximum approaching 100e. When the 2nd stage fan is activated, it immediately reduces the heat.

The situation is just around 80 in this. Then I am relieved by saying that it is an ordinary situation in our vehicles. Thanks :)

In diesel, I do not know if the engine temperature is different, but in the first place, the reason for my thermostat change was the low temperature until the 70s. I think you can insert a 50 lira piece and try it.

Let me just plug it in and try. We corrode the engine and burn excess fuel using it at low temperatures.
