Is Hararet Normal?

Before the friends changed the thermostat, the temperature would come to 90 with stop and get up. But after changing the thermostat, even in the early morning, it comes to the place in the picture. Stop and go up. But do you think it is normal to reach this level with a 10-minute cruise in the morning coolness?

normal brother no problem

I think it doesn't matter much in the morning when it's hot.

Thanks guys .. We are giving so many breakdowns in a row that I started to be paranoia from everything.
