Cleaning Circuit Refrigeration ????

HELLO!! I would like to clean my vehicle the refrigeration circuit, radiator and others but I do not know how to start ... I will empty the circuit through the screw that I have under the radiator but then instead of directly throwing the new refigrant liquid I would like to clean everything inside ... they will comment with hose water releasing a sleeve and ahcan that the circuit passes the circuit but I am not sure if it is good. Well throw vinegar and others ....
If someone can guide me a little, I would appreciate it ... Greetings.

Hello friend there is a product that sells to clean I recommend you place that product since it has to last a time circulating the water then to the days you take x the drain that goes down the radiator that carries a plug and it looks better

Thank you very much ... I will look to see liquid it's ...

It is veric what says fried, but you must be careful, sometimes the remedy is worse than the disease.
