Black Smoke Problem

206 1.4 I have a car, the car starts out, black smoke comes out, it turns out, then it is cut off. Do you have any suggestions, such as the exhaust outlet side is black

up

I have a second question. The tank where we put the cooling water is making air continuously. No matter where I look, I did not see the place in a short time. When I stop this at the same time, when I squeeze the tank lid completely, it would hurt the pressure from the face.

Replace the teacher tank cap may be damaged. Do not leave any of our vehicles' cooling system closed circuit cover loose. When it comes to black smoke, it can generally be from injector-egr.
