You said you fill the radiator with water. It should be filled with 50/50 antifreeze/water to protect it from corrosion and the cooling jacket of the engine from rust. Also, the rad should only be filled to the top of the core, leaving the rest of the rad for expansion space of the coolant. Check the pressure cap to make sure it's holding pressure. If you can't find anyone to check it for you, replace it with the correct cap and see if that helps.
The fact that you got nasty looking stuff out of the radiator could mean that you have a lot of corrosion in the cooling system. You may also have a leaking head gasket or a crack in the head. Remove the rad cap and start the engine. When the thermostat opens look into the top of the rad and see if you can see a steady stream of bubbles. If you do, then I'd suspect a leaking headgasket or a cracked head.
Hope this helps.
