Change the thermostat.
Check the radiator electro-ventilator as indicated by the User Osvalmas that says
you fix the electro fan. It can become that it is not working properly. In most cars, the electro has 2 speeds, if it does not go down, then when it lifts more temperature lights the second speed and then the temp. You can check this with the stopped vehicle, you let it heat and when it is at normal temperature you see if the electro starts, if it does not work and continues to rise, and starts when it reaches more than 100 ° in high speed, then the first speed does not work.
The other possibility is that you arrive at a workshop that has a scanner with which connected to the vehicle can be tested the two electro-ventillator speeds,
another is that you answer the messages of the users who are helping you and if you already solved the problem, indicate by this means
help you to help you
