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

[demolitionMan]

Hello guys, I'm desperate.
I have the following problem with my 147 1.9 jtdm 150 hp.

machine hot (90 ? engine temperature, as soon as I turn the ricaldamenti, the temperature goes up to 50-60? with tempereatura external 8 ? about! in about 1-2 minutes the temperature drops and in the passenger compartment only gets warm (almost cold)!...

if I have the hot air on and walk into town? the temperature of the engine at every red light falls in the range of 10-15 ? .of course, if I'm stationary with the engine on if I want hot air in the cockpit, I have to accelerate the car up to 2000 rpm so constant !


I changed the thermostat valve 2 times .

up to a month ago, even with the machine stopped, I had the hot temperature and the engine temperature was fixed at 90? even at temperatures + rigid!

Thanks to all of you.

from the diagnosis you have the same temperatures?

Check with the diagnosis of the temperature on the instrument panel and the temperature in the engine control unit, and if they are equal, sure that the thermostatic valve and defective.

diagnosis and all true! even why? when the temperature drops to 60 degrees feels that it is cold in the car! the hand on the picture ? busted! the thermostatic valve I have replaced it 2 times with a marked Vernet and another alfa! everything remains the same!

usually the problem! I open the warm air and the temperature drops! if you do not open the air temperature is fixed at 90?

Do you drink water? maybe you have air in the heating circuit? I also have a 147 but jtd 115 and does a similar job but not when ? 90?, he does this when ? around 60-70 that as soon as I turn on the hot air the temperature drops suddenly!

Anchio contollerei good as it circulates the water on the same type of engine to another car I found in the water pump of the vane broken in the impeller that ? plastic

And one thing that is very strana.Doveva be to force the valve termostatica.Controlla if there is not some manigotto reversed

The water circulates very well, not eating certainly! if it was the pump the car should warm up ! but this is cool! not ? a normal thing! usually all of have the opposite problem! it heats up! but to me it cools!

You will soon pubblicher? a video of how it lowers the temperature when I open the hot air..
