ALFA 147 : Problem low engine temperature , as soon as I turn the hot air!

[Backgroop]

Replace the thermostat and go quiet, surely ? perfectly calibrated, and opens at low temperatures or when it opens it stays open..

from what I read, considering also the thermostat ori seems to have changed 3 in all of these components.....
now..I don't think that all 3 thermostats are faulty.....or don't read the topic??all you do is read the last post in question and write so much to increase the counter of the post???
maaahhhh??!!???

[Tom79]

depends if thermostatic radiator valves included in the thermostat...

[munro]

sorry tom79, because thou in the thermostatic valves of the 147 you can change only the thermostatic valve without replacing the entire thermostat????

[munro]

and anyway since you want to do the picky....thermostat or thermostatic valve shall indicate in the automotive sector is the same component.

the problem over to the thermostat could be linked to the pressure switch on the air conditioning not functioning properly, start the fans and, consequently, lower the operating temperature.

But as a fan you mean the ones of the cooling radiator of the water? well, to me, those don't run ever!.. the thermostat I replaced it 2 times! the valves I try to do open and close to tour, by heating a pot of water, I set the valves (monitoring the temperature of the water)but it seems to work perfectly!. thanks to all for the answers.

Try to verify the return of water ( with the car in motion check that the tube and the small one on the bowl water comes out) if not, proceed to the cleaning ... it often happens that it becomes clogged
