You will need to drain the cooling system. Best way of doing that is by removing the pipe at the bottom of the radiator.
Not sure exactly where or how easy is its to get to on the mondeos but at the bulkhead you should see to pipes leading into the car. Be roughly in the middle. You need to remove them as well.
The best way I've found to unblock it its to force water down where you removed one of the pipes and see if it comes out the other one. Don't put too high a pressure in there though or you could damage something. The sort of pressure you would get by sticking your thumb over the end of a garden hose.
I've used a pressure washer before but at a distance
Wouldn't recommend you doing this though.
After removing any blockage connect all the pipes back up and fill the coolant back up. Leave the cap of and let the engine warm up to let it bleed out.
