Heating in a Peugeot 405 Diesel

The Peugeot 405 Diesel with XUD9 motor is heated when it passes the 120 130 kilometers, with the air conditioning operating if under the speed or removes the air conditioning lowers the temperature that ocilas in trees 100 grade and if I leave it more in the city with great heat in the environment and working in low not over 80 degrees, this engine has Turbo Inter cooler, please if any talented person in this matter can help me. Well, I have no people capped in Cuba for this or at least I do not meet them, greasias

Check that the radiator is not semited and controls whether the thermostat works well and the electrventilator couples as appropriate, tell us how you are doing, greetings.

Greetings, when the compressor enters, you have to turn on the fans, check it, clean the intercooler with degreaser, it will do well, apart from everything, these engines need that working temperature, do not scare yourself, you can put a colder thermostat, or make a small drill you have, to take more step, but I repeat you, it is the normal temperature of the XUD, 98-100
