I don't remember seeing a posting about how to flush a radiator to get out all the deposits.  And what kind of liquid to use to free the deposits up.  I can hook up a separate pump with two different hoses to it, so only the radiator would be involved.  Do I need a certain pressure to push out the dirt?  Do I need to do it both direction?
Anyone know anything about this kind of work?  Do I need a filter with flush like that?
I have tried to hook up the garden hose, but other than the water going through freely, I did not achive any positive result.
Maybe I have to soak it with some liquid inside for a day to lift the deposits, then flush?
