Remove air refrigerant circuit mk3

The thermostat seems to open and it is fine. Only when the water is heated to you through the plug by pressure, so I see you are not recirculating the liquid well, and if you remove the belt housing and look to see the pump if it has a water ozume on the outside.

I tell you why the unique times that I have been the case that the bottle safety plug is out of it is because the liquid does not move. By blocked thermostat or broken pump.

It is the only thing that you have left to look, or that that car is widowed with tap water and this whole block full of lime stones that does not let the water run.

Nor do I want to dizzy, they sell water circuit cleaners for about 8 or 9 euros, and what you see.

Thank you very much, what I will do will be to change all those pieces and put them new because it gives me that they have never changed them, although the first thing that will do will be to change the plug that the same the valve does not do its function well. Thanks again for your help.
