This is a massive job that requires removal of the complete dashboard and heater box.Even worse if it has air con.hth

I reckon a couple of days. You'll probably need an assistant to help you lift the facia out and back in too.

Why don't you give the whole system a good flushing and then refill but with the addition of a can of proprietory leak sealant? If it works this will save you an awful lot of effort.
