Renault Express 1.6D
I have changed the tube of the upper sleeve of the pump or bottle of expansion of the antifreeze that goes to the engine, and I get jet from the engine until the bottle is emptied, but from the radiator nothing, does not empty.
My question:
How is the antigongeling liquid circuit purged?
There must be a cap below on the radiator, but I can't find it.
After purging it, what do I do?
It is full of the radiator and after the bottle, or everything is done to the expansion bottle?
If I get to know I do not change the eggs of the eggs, mother like my garage, it seems a running escape.

Well thanks in advance.
