2.0 HDI Adventure Temperature Rise

friends first of all hello i dont know how to use the full forum, so the location of the subject is maybe wrong, my car is 2.0 HDI partner adventure. I am very happy at 168.000 km and I am very satisfied with fuel, but there is a problem of heat in my vehicle, there is no water boiling etc. But the temperature is over 90 even on the long road and the line above 90 is over, so the fan hurts even on the long road. the radiator is clean, the circulation has just changed, and the thermostat is not defective, but it still does the same, but the water does not boil. what is the reason of this ? Canakkale successful peugeot could not solve the vehicle's malfunction. I wanted to share it with you, perhaps because it was an incident that a friend of mine was in the press.

If your car is 4000 or whatever you are going on, you should fall below 90 if you normally go with 2500-3000 revolutions on the long road, but you should avoid sudden accelerations and movements .. I think there is a usage problem.

Interesting. Maybe the thermostad is not doing its job properly, maybe there is a problem in the client. In my vehicle, the temperature that changes between 50 and 100 before the thermostad changes is now generally fixed at 90 degrees. It reaches 99 degrees in extreme strains and if I go downhill for a long time, it no longer falls below 80 degrees.

Actually, I don't use high speed. Besides, the vehicle is doing 110 at 2200 rpm on the long road. What exactly is the line you say ahmet 99 degrees? Is it under red?

the thermostat has changed, the car is still the same, we have not changed, the radiator is left, let's see what happens when you change it

first you have to doubt the client

After my thermostad, the car got a little more comfortable working around 90. The 100 line is also above 90. We say 110 under red 1 God knows how many degrees ...
