Antifreeze depletion

Friends greet everyone. I need your urgent help. My car 2004 model 307 1.4 HDI.
In my car, there was an error of cooling water missing. I checked the antifreeze was reduced. Half antifreeze was cut off. Let me drip from the engine block, which corresponds to the right bottom corner of the air filter. I wonder how much trouble can be eliminated where this place can be.

Sank running around where the thermostat is ..

Sir, I have a photo, but I couldn't add it. Could there be a circulation pump, is the circulation pump located on the right side of the engine or on the left?

Friends, who would you recommend to me who understands a reliable peugeot repair in Bursa?

If I evaluate my vehicle 1,4i 16V sport from your own car, the outlet pipe of the radiator in the circulation may be damaged, I guess it will not be much more than 50-60 TL.

There is a radiator occluder I put it cut. try

According to your opinion and other research that I have done, I think it is around the water collector (slab) or thermostad. It was good to have a preliminary information to a master at the first opportunity. Thank you for your interest.

I do not think that the clogging powder will solve the problem, not in the radiator, but in the engine body.

It is not in my radio, it is already missing from the surrounding of a pipe.

I guess we are antifreeze
is missing from the thermostat gasket ..

Does anyone have information about thermostat removal. Is thermostat gasket sold separately?

Slm..you changed the antifreeze of my car .. not taking it all. I put water as it decreases ... now we have a little more antifreeze ... if I put it in place of water? How long should I look at this antifreeze..It seems to be cut off to me too much ... I wait for a month of water or every two months ..

I just looked at the antifreeze. I didn't know if I would add a minimum level ??

Friends today I dismantled the antifreeze leaking thermostat. The dismantling work was quite difficult because it was a narrow point where the transportation and switch maneuver was difficult. As a result, I removed the thermostat. In this way I put the thermostat in place and let it dry for today.
Friends antifreeze, the help I expect from you, from which points do we get the air after putting on the radiator, the engine had to work while taking the air, and is there any other step to be done?
I will put your antifreeze as the end of the job tomorrow. I am waiting for your help in this regard.

While the engine I know is working, there is a valve in the radiator and I bought it in alpha. There is a valve in the pejo.

Last week, I changed the thermostat, it was missing from the thermostat.
